항균, 항바이러스 및 탈취 효과를 가진 항균막 및 그 제조방법Antibacterial film having antibacterial, antiviral and deodorizing effects and its manufacturing method

It relates to an antimicrobial membrane having and a method for manufacturing the same.
최근에 들어 국민들의 건강보건의식이 높아짐에 따라 다양한 용도로 사용될 수 있는 항균성을 가지고 있는 소재에 대한 수요가 증대되고 있다. 특히, 대중이 다수 이용할 수 있는 공용물품이나 사용자의 손에 자주 접촉될 수 있는 핸드폰과 같은 소형전자기기의 경우에는 항균성을 가지는 재료를 이용하여 만들어지는 것이 최근의 추세이다.In recent years, as people's health awareness has increased, the demand for materials having antibacterial properties that can be used for various purposes is increasing. In particular, in the case of public goods that can be used by many people or small electronic devices such as mobile phones that can frequently come into contact with the user's hands, it is a recent trend to use materials having antibacterial properties.
또한, COVID-19, 신종인플루엔자와 같이 전염성 높은 유행성 질병이 급속히 전파됨에 따라 공포감으로 인하여 개인위생 의식이 더욱 강화되고 있을 뿐만 아니라 이를 충족시킬 수 있는 항균성 및 항바이러스성 소재에 대한 수요가 급증하고 있다.In addition, as highly contagious epidemic diseases such as COVID-19 and swine flu spread rapidly, not only personal hygiene awareness is being strengthened due to fear, but also the demand for antibacterial and antiviral materials that can meet this is rapidly increasing. .
구체적으로, 차량, 가정 등의 실내 등의 폐쇄된 공간이나, 침구, 학생들의 공부방, 아기방 등 보다 쾌적하고 깨끗하 게 유지되어야 하는 공간이나, 학원, 사무실, 병원, 요양시설, 숙박시설, PC방 등 많은 사람이 함께 쓰는 공간에는 바이러스, 곰팡이 등의 세균이 번식하는 것을 방지하는 항균 및 탈취가 보다 중요할 수 있다.Specifically, closed spaces such as vehicles and homes, spaces that need to be kept more pleasant and clean, such as bedding, students' study rooms, nurseries, academies, offices, hospitals, nursing facilities, accommodations, and PC rooms In a space shared by many people, antibacterial and deodorizing agents that prevent the propagation of bacteria such as viruses and molds may be more important.
이러한 환경적 요인에 따라 항균력을 가진 소재들이 일상 생활 많은 부분에서 활용되고 있다. 예컨대, 세균, 박테리아에 내성을 가진 항균성이 부여된 항균 필름들이 개발되어 출시되고 있으며, 일상 생활에서 인체와 접촉하는 거의 대부분의 물체나 공간에 부착된다. 현재 일반적으로 보급되는 필름은 구리나 은을 주 성분으로 하고 있으나, 이러한 항균 필름의 실질적인 항균 기능에 대해서는 여전히 의문이 남아 있다. 항균 필름을 부착하는 곳은 그만큼 여러 사람의 접촉이 잦은 위치이므로 빠르게 강력한 항균 및 항바이러스 효과를 달성할 수 있어야 한다. 그러나, 일반적으로 이용되는 구리나 은을 함유하는 필름은 일반적인 병원 균에 대해 24 시간 동안의 항균성만 보고되고 있으며, 그보다 더 빠른 시간 내 항균이나 항바이러스 효과를 달성할 수 있는지에 대해 보고된 바가 없다. 더욱이 이러한 필름들이 COVID-19 바이러스에 대해서는 99%에 달하는 항바이러스 효과를 달성할 수 있는지 충분히 검증된 바가 없다. 추가적으로, 구리를 이용한 다양한 형태의 항바이러스 및 항균용 조성물에 대한 개발이 시도되고 있으나, 조성물을 구성하는 용매 내에서 구리의 분산성 및 분상안정성이 낮다는 문제가 있었다. 용매 내에서 구리의 분산성 및 분산 안정성이 낮을 경우, 층분리 또는 침전물 형성의 문제가 발생되며, 이에 따라 항바이러스 및 항균 효과가 저하된다는 우려가 존재한다.According to these environmental factors, materials with antibacterial activity are being used in many parts of daily life. For example, antibacterial films with antibacterial properties resistant to germs and bacteria have been developed and released, and are attached to almost all objects or spaces that come into contact with the human body in daily life. Currently, generally distributed films contain copper or silver as a main component, but questions remain about the actual antibacterial function of these antibacterial films. Since the place where the antibacterial film is attached is a place where many people come into contact with it, it should be able to quickly achieve strong antibacterial and antiviral effects. However, generally used films containing copper or silver have been reported only for 24 hours of antibacterial activity against common pathogens, and there has been no report on whether antibacterial or antiviral effects can be achieved within a shorter period of time. . Moreover, it has not been sufficiently verified that these films can achieve an antiviral effect of up to 99% against the COVID-19 virus. Additionally, although development of various types of antiviral and antibacterial compositions using copper has been attempted, there has been a problem in that dispersibility and phase stability of copper in the solvent constituting the composition are low. When the dispersibility and dispersion stability of copper in the solvent are low, a problem of layer separation or precipitate formation occurs, and accordingly, there is a concern that antiviral and antibacterial effects are lowered.
이에, 다양한 물품에 부착 가능하여 항균, 항바이러스 및 탈취 효과를 발생시키는 항균막을 구현하기 위한 지속적인 연구 개발이 요구되고 있다.Accordingly, there is a demand for continuous research and development to implement an antibacterial film that can be attached to various articles and generates antibacterial, antiviral, and deodorizing effects.

Specifically, the nanoalloy composition included in the thin film layer 130 and the coating layer 140 may be a composition that generates an electromagnetic field by itself. The nanoalloy composition is generated based on an alloy of a diamagnetic component material selected from copper, gold, silver, and bismuth, and a ferromagnetic substance such as iron, Nitel, cobalt, and neodymium, or a paramagnetic component material such as platinum, and generates an electromagnetic field by itself. It can be characterized by doing. For example, the nanoalloy composition may be a composition including an alloy of diamagnetic copper and ferromagnetic iron, that is, a copper-iron alloy.

In this case, an electromagnetic field is generated by itself according to the principle that the electric field is changed by the change of the magnetic field of ferromagnetic components such as iron, nickel, and cobalt (based on Faraday's law related to the induction of the electric field and the magnetic field between corals). For example, each of the diamagnetic component and the paramagnetic component has a two-dimensional stacked structure in which layers are separated, and an electromagnetic field can be generated based on Faraday's law. In one embodiment, by adding additional additives such as Zn, Mg, K, P, Cl, Ca, I, Si, Ti, Al, etc. to cause a change in dielectric constant, the electromagnetic field generated from the antimicrobial membrane 100 can be changed or adjusted. can

일 실시예에 따르면, 구리는 미량동 작용에 기반한 항균 작용을 수행할 수 있다. 미량동 작용은 구리원자가 미생물의 대사작용을 교란시켜 바이러스나 미생물, 곰팡이 등을 살균하는 것으로, 박테리아의 핵산이 완전히 파괴되면서 돌연변이 뿐만 아니라 저항성 조차 완전히 제거하는 효과를 제공할 수 있다. 다시 말해, 구리 이온(또는 금속 이온)의 미량동 작용을 통해 균의 활성이 방해됨에 따라 항균 작용이 수행될 수 있다. According to one embodiment, copper may perform an antibacterial action based on microcosmic action. Microbial action is to sterilize viruses, microorganisms, fungi, etc. by disturbing the metabolism of microorganisms by copper atoms, and can provide the effect of completely removing not only mutations but also resistance as the nucleic acids of bacteria are completely destroyed. In other words, antibacterial action can be performed as the activity of bacteria is hindered through the action of copper ions (or metal ions) in small amounts.
전술한 바와 같이, 항균막(100)이 반자성체에 관련한 금속 이온(예컨대, 구리이온)을 포함하여 구성됨에 따라 항균 작용을 수행할 수 있다. 다만, 바이러스는 숙주 외부에서는 대사활동하지 않으므로, 구리의 미량동 작용에 의해서는 사멸되지 않을 수 있다. 다시 말해, 금속 이온을 통해 항균 작용은 수행될 수 있으나, 항바이러스 작용은 수행될 수 없다.As described above, as the antimicrobial film 100 is configured to include metal ions (eg, copper ions) related to the diamagnetic material, an antibacterial action may be performed. However, since the virus does not undergo metabolic activity outside the host, it may not be killed by the action of copper in trace amounts.

Specifically, the antimicrobial membrane 100 may generate an electromagnetic field by itself.

In this case, the nanoalloy composition is formed through a two-dimensional laminated structure separated between each component, and an electromagnetic field is generated based on the Faraday effect. In other words, an electromagnetic field is generated in the antimicrobial film 100 through the nanoalloy composition related to the alloy composition of the diamagnetic and paramagnetic or diamagnetic and ferromagnetic substances, and the virus can be killed through the resulting electrostatic force. That is, antiviral action can be performed as the virus is blocked by the electromagnetic field.
또한, 항균막(100)은 탈취 작용을 수행할 수 있다. 구체적으로, 항균막(100)의 코팅층(140)은 광촉매소자를 포함하여 구비될 수 있으며, 해당 코팅층(140)에 포함된 광촉매소자를 통해 탈취 효과를 발생시킬 수 있다. 광촉매 소자는 적정 에너지 이상을 갖는 빛 또는 파장에 대응하여 활성산소, 수신기 라디칼을 발생시키는 반도체적 성질을 갖는 소자를 의미할 수 있다. 광촉매 소자를 통해 발생된 활선산소와 수신기 라디칼의 강한 산화, 환원 작용에 의해 악취물질의 분해될 수 있다.In addition, the antibacterial film 100 may perform a deodorizing action. Specifically, the coating layer 140 of the antibacterial film 100 may include a photocatalytic element, and a deodorizing effect may be generated through the photocatalytic element included in the corresponding coating layer 140 . The photocatalytic device may refer to a device having semiconductor properties that generates active oxygen and receiver radicals in response to light or wavelengths having more than appropriate energy.

Here, the film refers to a film (or plate) having a certain level of transparency or more, and may be provided by being attached to an object or region that can directly contact the user's body. Also, for example, as the base layer 120 is composed of PP or Polyester, the antibacterial membrane 100 may be implemented in the form of a filter or clothing. Here, the filter is for filtering out foreign substances in the gas, and may refer to a membrane, layer, surface, or the like that cleanly filters intake air from an indoor ventilation system or an engine.
즉, 도 2에 도시된 바와 같이, 본 개시의 항균막(100)은 기재층(120)을 구성하는 소재에 따라, 다양한 분야에서 활용 가능하도록 구비될 수 있다. 예를 들어, 항균막(100)은 필름의 형태로 구비될 수 있으며, 불특성 다수의 이동이 빈번한 다양한 영역(예컨대, 철도, 지하철, 버스, 자동차 등의 손잡이)에 부착되거나 또는 건물 또는 자동차 창의 윈도우 필름으로 활용될 수 있다.That is, as shown in FIG. 2, the antimicrobial membrane 100 of the present disclosure may be provided to be utilized in various fields depending on the material constituting the base layer 120.

It can be used as a window film.

이러한, 점착층(110)은 점착제를 활용한 습식코팅을 통해 형성되는 것을 특징으로 할 수 있다. 구체적으로, 점착층(110)은 액체 상태의 점착제를 지지면에 도포하는 습식코팅 방식을 통해 형성될 수 있다. 여기서 지지면은 점착층(110)의 형성 과정에서 점착제를 일시적으로 지지하기 위해 구비되며, 점착층(110)의 형성 이후 이탈될 수 있다. The adhesive layer 110 may be characterized in that it is formed through wet coating using an adhesive.

마이크로 그라비아 코팅은, 코팅롤의 접촉각을 최소화하기 위하여 코팅롤의 반경을 소형화하여 롤 표면과의 접촉범위를 극소화 함으로 박막의 도료를 균일하게 도포하는 정밀 코팅 방식일 수 있다. 또한, 콤마 코팅은, 콤바 형태의 바를 이용하여 점착액(즉, 액체 상태의 점착제)을 도포하는 방식으로, 점착액의 점도가 높거나 도포 두께를 높일 때 활용되는 코팅 방식일 수 있다.Micro gravure coating may be a precision coating method that uniformly applies a thin film of paint by minimizing the radius of the coating roll to minimize the contact angle of the coating roll and minimizing the contact range with the roll surface. In addition, comma coating is a method of applying an adhesive liquid (ie, liquid-state adhesive) using a comba-shaped bar, and may be a coating method used when the viscosity of the adhesive liquid is high or the coating thickness is increased.
즉, 점착층(110)은 액체 상태의 점착제에 대한 점착 코팅(또는, 습식 코팅)을 통해 형성될 수 있으며, 생성된 점착층(110)을 통해 항균막(100)이 다양한 영역에 접촉 가능하게 구비될 수 있다.That is, the adhesive layer 110 may be formed through adhesive coating (or wet coating) of the liquid adhesive, and the antimicrobial film 100 can contact various areas through the generated adhesive layer 110. may be provided.

(S130) may be included. The thin film layer 130 may be formed of a nanoalloy composition including at least one of an alloy of a diamagnetic material and a ferromagnetic material or an alloy of a diamagnetic material and a paramagnetic material to generate an electromagnetic field.
자세히 설명하면, 박막층(130)을 형성하는 나노합금 조성물은, 반자성체 성분의 재료와 강자성체 성분의 재료의 합금 또는 반자성체 성분의 재료와 상자성체 성분의 재료의 합금 중 적어도 하나에 대한 분쇄를 통해 획득될 수 있다. 나노합금 조성물은, 구리, 금, 은, 비스무트 등에서 선택된 반자성체 성분과, 철, 니텔, 코발트, 네오디뮴 등 강자성체 또는, 백금 등 상자성체 성분 과의 합금에 기반하여 생성될 수 있다. 예를 들어, 나노합금 조성물은, 반자성체인 구리와 강자성체인 철의 합금 즉, 구리-철 합금에 관련한 나노분말을 포함하는 조성물일 수 있다. 전술한 나노합금 조성물에 대한 구체적인 기재는 예시일 뿐, 본 발명은 이에 제한되지 않는다.In detail, the nanoalloy composition forming the thin film layer 130 may be obtained by grinding at least one of an alloy of a diamagnetic component material and a ferromagnetic component material or an alloy of a diamagnetic component material and a paramagnetic component material. there is. The nanoalloy composition may be produced based on an alloy of a diamagnetic component selected from copper, gold, silver, bismuth, and the like, and a ferromagnetic component such as iron, Nitel, cobalt, and neodymium, or a paramagnetic component such as platinum. For example, the nanoalloy composition may be a composition including nanopowder related to an alloy of diamagnetic copper and ferromagnetic iron, that is, a copper-iron alloy. The specific description of the above-described nanoalloy composition is only an example, and the present invention is not limited thereto.
반자성체 성분의 재료와 상자성체 성분의 재료(또는 강자성체 성분의 재료)를 통해 합금 조성물로 구성하는 경우, 구리, 금, 은, 비스무트 등 전도성 금속물질(즉, 반자성체 성분)의 산화환원에 의한 전기장 변화에 의해 자기장이 변화되게 될 수 있다. 이 경우, 철, 니켈, 코발트 등 강자성체 성분의 자기장의 변화에 의해 전기장이 변화하는 원리(전기장과 자기장의 산호간 유도현상에 관련한 패러데이 법칙에 의거)에 의해 스스로 전자기장을 발생시키게 된다. 예컨대, 반자성체 성분과 상자성체 성분 각각이 층이 분리된 2차원 적층구조를 가지며, 패러데이 법칙에 의거하여 전자기장을 발생시킬 수 있다.When composed of an alloy composition through a material of a diamagnetic component and a material of a paramagnetic component (or a material of a ferromagnetic component), the electric field change due to the oxidation-reduction of conductive metal materials such as copper, gold, silver, and bismuth (ie, the diamagnetic component) The magnetic field can be changed by In this case, an electromagnetic field is generated by itself according to the principle that the electric field is changed by the change of the magnetic field of ferromagnetic components such as iron, nickel, and cobalt (based on Faraday's law related to the induction of the electric field and the magnetic field between corals). For example, each of the diamagnetic component and the paramagnetic component has a two-dimensional stacked structure in which layers are separated, and an electromagnetic field can be generated based on Faraday's law.
즉, 반자성체 성분과 상자성체 성분(또는 강자성체 성분)을 포함하여 구성되는 나노합금 조성물은, 스스로 전자기장을 발생시킬 수 있다. 다시 말해, 나노합금 조성물을 통한 증착으로 형성되는 박막층(130)은 스스로 전자기장을 발생시킬 수 있다.That is, the nanoalloy composition including the diamagnetic component and the paramagnetic component (or ferromagnetic component) may generate an electromagnetic field by itself. In other words, the thin film layer 130 formed by deposition through the nanoalloy composition may itself generate an electromagnetic field.
실시예에서, 나노합금 조성물은 용매 내에 구리-철 합금의 나노분말이 분산된 분삭액 형태로서, 용매 내에서 구리-철 합금의 나노분말의 분산성 및 분산안정성이 우수할 수 있으며, 이에 따라, 현저히 향상된 항바이러스 및 항균 효과를 구현할 수 있다. 구체적인 예를 들어, 나노합금 조성물은, 반자성체 성분의 재료인 구리와 강자성체 성분의 재료인 철 즉, 구리-철 합금에 기반하여 생성된 조성물을 의미할 수 있다.In an embodiment, the nanoalloy composition is in the form of a dispersion solution in which the nanopowder of the copper-iron alloy is dispersed in a solvent, and the dispersibility and dispersion stability of the nanopowder of the copper-iron alloy in the solvent may be excellent. Accordingly, Significantly improved antiviral and antibacterial effects can be realized. For example, the nanoalloy composition may refer to a composition created based on copper as a material of a diamagnetic component and iron as a material of a ferromagnetic component, that is, a copper-iron alloy.
보다 구체적으로, 나노합금 조성물은 나노분말, 용매 및 계면활성제를 포함할 수 있다.More specifically, the nanoalloy composition may include a nanopowder, a solvent, and a surfactant.
나노분말은, 반자성체 재료와 강자성체 재료 또는 반자성체 재료와 상자성체 재료 중 적어도 하나의 합금에 관련한 것일 수 있다. 예를 들어, 나노분말은, 구리-철 합금에 관련한 것으로, 구리와 철이 9 대 1 비율로 포함된 합금을 의미할 수 있다. 일 실시예에서, 구리의 비율이 적어지거나(예컨대, 구리의 비율이 전체 비율에서 80% 이하인 경우) 또는 현저하게 커지는 경우(예컨대, 구리의 비율이 전체 비율에서 99% 이상인 경우), 해당 나노분말을 통해 구현되는 나노합금 조성물의 항바이러스 및 항균 효과가 저하될 수 있다.The nanopowder may relate to an alloy of at least one of a diamagnetic material and a ferromagnetic material or a diamagnetic material and a paramagnetic material. For example, the nanopowder relates to a copper-iron alloy, and may refer to an alloy containing copper and iron in a ratio of 9:1. In one embodiment, when the copper ratio decreases (eg, when the copper ratio is 80% or less in the total ratio) or significantly increases (eg, when the copper ratio is 99% or more in the total ratio), the nanopowder Antiviral and antibacterial effects of the nanoalloy composition implemented through may be reduced.
나노분말은, 입자 크기가 미리 정해진 크기 이하인 나노분말을 의미할 수 있다. 예컨대, 나노분말은, 구리-철 합금을 1~100 나노미터의 크기로 분말화한 것을 의미할 수 있다. 전술한 나노분말의 크기에 관련한 구체적인 수치적 기재는 예시일 뿐, 본 발명은 이에 제한되지 않는다. 추가적인 실시예에 따르면, 나노합금 조성물은 나노분말이 분산된 분산액 형태이되, 용매에 나노분말이 200 내지 800 ppm의 농도를 통해 구비될 수 있다.The nanopowder may refer to a nanopowder having a particle size equal to or less than a predetermined size. For example, the nanopowder may mean a powdered copper-iron alloy to a size of 1 to 100 nanometers. The specific numerical description related to the size of the nanopowder described above is only an example, and the present invention is not limited thereto. According to a further embodiment, the nanoalloy composition may be in the form of a dispersion in which the nanopowder is dispersed, and the nanopowder may be provided in a solvent at a concentration of 200 to 800 ppm.
일 실시예에 따르면, 반자성체 성분의 재료는, 미량동 작용을 발생시키는 것을 특징으로 할 수 있다. 예컨대, 본 발명의 박막층(130)에 포함된 반자성체 성분은 구리를 의미할 수 있다.According to one embodiment, the material of the diamagnetic component may be characterized in that it generates a microcosmic action. For example, the diamagnetic component included in the thin film layer 130 of the present invention may mean copper.
미량동 작용은, 구리원자가 미생물의 대사작용을 교란시켜 바이러스나 미생물, 곰팡이 등을 살균하는 것으로, 박테리아의 핵산이 완전히 파괴되면서 돌연변이 뿐만 아니라 저항성 조차 완전히 제거하는 효과를 발생시킬 수 있다. 다시 말해, 본 발명의 박막층(130)은 구리를 포함하여 구성(즉, 구리-철 나노분말을 포함하여 구성)됨에 따라 미량동 작용을 통한 항균 작용을 수행할 수 있다. 도 4는 본 발명의 일 실시예와 관련된 구리를 통해 수행되는 항균 작용을 설명하기 위하여 예시적으로 도시한 도면이다.Microbial action is to sterilize viruses, microorganisms, fungi, etc. by disturbing the metabolism of microorganisms by copper atoms. As the nucleic acids of bacteria are completely destroyed, not only mutations but also resistance can be completely eliminated. In other words, as the thin film layer 130 of the present invention is composed of copper (ie, composed of copper-iron nanopowder), it can perform an antibacterial action through a micro copper action. 4 is a diagram exemplarily shown to explain an antibacterial action performed through copper related to an embodiment of the present invention.
구체적으로, 도 4를 참조하면, 박테리아 세포(200)는 구리 표면의 구리 이온(210)을 꼭 필요한 영양소로 인식하여, 구리 이온(210)을 체내로 흡수할 수 있다. 즉, 구리 이온(210)이 박테리아 세포(200)를 뚫고 내부로 침투하게 된다(S210). 박테리아 세포(200)의 체내로 침투한 구리 이온(210)은 세포막의 내부 및 외부 간의 전위차를 불안정하게 교란시키며, 이에 따라 박테리아 세포는 내부의 중요한 영양분과 수분을 잃게되어 점차 세포막이 파괴되게 된다(S220). 또한, 구리 이온(210)이 외부의 활성산소종(220)을 유인하여 박테리아 세포의 손상을 가속화시킬 수 있다(S230). 여기서 활성산소종은 화학적으로 활성화된 즉, 불안정한 산소를 포함하는 화학물질을 의미하는 것으로, 예컨대, 과산화수소와 같은 과산화물(peroxide), 초과산화물(superoxide), 수산화 라디칼(hydroxyl radical), 단일항 산소(singlet oxygen) 등을 포함할 수 있으나, 이에 제한되지 않는다. 활성산소종(220)은 산소분자로부터 유래된 여러 종류의 반응 분자와 자유라티칼을 포함할 수 있다. 라디칼과 연관된 산소 화합물들은 산소 호흡을 하는 생명체들에게 위험한 요인일 수 있다. 즉, 박테리아 세포(200)에 침투한 구리 이온(210)이 활성산소종(220)을 유인할 수 있으며, 이러한 활성산소종(220)에 의한 여러 불균형이 초래되어 박테리아 세포(200)의 손상을 가속화시킬 수 있다. 또한, 구리 이온은 게놈 및 플라스미드 DNA 분해를 수행하며, 세포 복제와 자가 증식을 차단하여 박테리아 세포의 세포 호흡과 신진대사를 방해할 수 있다(S240).Specifically, referring to FIG. 4 , the bacterial cells 200 may recognize the copper ions 210 on the copper surface as essential nutrients and absorb the copper ions 210 into the body. That is, the copper ions 210 pass through the bacterial cells 200 and penetrate into the inside (S210). The copper ions 210 penetrating into the body of the bacterial cell 200 unstablely disturb the potential difference between the inside and outside of the cell membrane, and thus the bacterial cell loses important nutrients and moisture inside, gradually destroying the cell membrane ( S220). In addition, copper ions 210 may attract external reactive oxygen species 220 to accelerate damage to bacterial cells (S230). Here, the active oxygen species refers to chemical substances that are chemically active, that is, include unstable oxygen, for example, peroxides such as hydrogen peroxide, superoxides, hydroxyl radicals, singlet oxygen ( singlet oxygen), etc., but is not limited thereto. The reactive oxygen species 220 may include various types of reactive molecules and free radicals derived from oxygen molecules. Oxygen compounds associated with radicals can be dangerous to oxygen-breathing organisms. That is, the copper ions 210 penetrating the bacterial cells 200 can attract the reactive oxygen species 220, and various imbalances caused by these reactive oxygen species 220 cause damage to the bacterial cells 200. can accelerate In addition, copper ions can degrade genomic and plasmid DNA, block cell replication and self-propagation, and interfere with cellular respiration and metabolism of bacterial cells (S240).
전술한 바와 같이, 구리 이온(또는 금속 이온)의 미량동 작용을 통해 균의 활성을 방해하여 항균 작용을 수행할 수 있다. 다시 말해, 세균이 대사작용으로 인해 구리 이온을 내부로 포함시키며, 이에 따라 세포막 파괴, 활성산소 발생에 의한 DNA, lipid 등의 파괴가 야기될 수 있다. 즉, 박막층(130)은 구리 이온을 포함하여 구성(즉, 구리-철 나노분말을 포함하여 구성)됨에 따라 미량동 작용을 통한 항균 작용을 수행할 수 있다.As described above, an antibacterial action can be performed by interfering with the activity of bacteria through the action of copper ions (or metal ions) in small amounts. In other words, bacteria include copper ions internally due to metabolism, which can cause destruction of cell membranes and destruction of DNA and lipids by generation of active oxygen. That is, as the thin film layer 130 includes copper ions (that is, includes copper-iron nanopowder), it can perform an antibacterial action through a micro copper action.
또한, 나노합금 조성물은 용매를 포함할 수 있다. 여기서 용매는, 나노분말이 분산되어지는 액을 의미할 수 있다. 용매는 분산된 분산액 형태로 형성될 수 있으며, 폴리에틸렌글리콜, 살리실산, 글리콜릭산, 저급 알코올 및 정제수를 포함할 수 있다. 일 실시예에서, 본 발명은 나노합금 조성물은 상기한 다섯 개의 물질을 모두 혼합하여 사용함으로서, 용매 내에서 나노분말의 분산성을 향상시키는 것을 특징으로 할 수 있다. 예를 들어, 총 용량을 기준으로 폴리에틸렌글리콜 25 ~ 45 중량%로 포함될 수 있으며, 살리실산이 3 ~ 7 중량%로 포함될 수 있으며, 글리콜릭산이 2 ~ 3 중량%로 포함될 수 있으며, 저급 알코올이 15 ~ 17 중량%로 포함될 수 있고, 그리고 잔량의 정제수를 포함하여 구성될 수 있다. 일 실시예에서, 저급 알코올은 에탄올일 수 있으나, 이에 제한되지 않는다. 추가적인 예를 들어, 저급 알코올은 메탄올을 통해 구성될 수도 있다.In addition, the nanoalloy composition may include a solvent. Here, the solvent may mean a liquid in which the nanopowder is dispersed. The solvent may be formed in the form of a dispersed liquid, and may include polyethylene glycol, salicylic acid, glycolic acid, lower alcohol, and purified water. In one embodiment, the nanoalloy composition of the present invention may be characterized by improving the dispersibility of the nanopowder in a solvent by using a mixture of all five materials. For example, based on the total capacity, polyethylene glycol may be included in 25 to 45% by weight, salicylic acid may be included in 3 to 7% by weight, glycolic acid may be included in 2 to 3% by weight, and lower alcohol may be included in 15 It may be included in ~ 17% by weight, and may be composed of the remaining amount of purified water. In one embodiment, the lower alcohol may be ethanol, but is not limited thereto. For a further example, the lower alcohol may be constituted via methanol.
또한, 나노합금 조성물은 계면활성제를 포함할 수 있다. 계면활성제는 분산안정성을 향상시키기 위한 것으로, 폴리비닐알코올(Poly vinylalcohol) 및 폴리비닐피롤리돈(Polyvinyl pyrrolidone)을 포함할 수 있다. 예컨대, 조성물을 구성하는 용매 내에서 구리의 분산성 및 분상안정성이 구리의 분산성 및 분산 안정성이 낮을 경우, 층분리 또는 침전물 형성의 문제가 발생되며, 이에 따라 항바이러스 및 항균 효과가 저하될 수 있다. 일 실시예에서, 계면활성제는, 폴리비닐알코올 및 폴리비닐피롤리돈을 1:9~10 중량비로 포함할 수 있다. In addition, the nanoalloy composition may include a surfactant. The surfactant is for improving dispersion stability, and may include polyvinyl alcohol and polyvinyl pyrrolidone. For example, if the dispersibility and dispersion stability of copper are low in the solvent constituting the composition, the problem of layer separation or precipitate formation may occur, and thus the antiviral and antibacterial effects may be lowered. there is. In one embodiment, the surfactant may include polyvinyl alcohol and polyvinylpyrrolidone in a weight ratio of 1:9 to 10.
본 발명의 계면활성제는 폴리비닐알코올 및 폴리비닐피롤리돈의 조합을 통해 구현되며, 분산안정성을 향상시킬 수 있음에 따라, 나노 분말에 대한 우수한 분산성과 분산안정성을 제공하여 항바이러스 및 항균성 효과를 극대화할 수 있다.The surfactant of the present invention is implemented through a combination of polyvinyl alcohol and polyvinylpyrrolidone, and as it can improve dispersion stability, it provides excellent dispersibility and dispersion stability for nanopowder, thereby providing antiviral and antibacterial effects. can be maximized.
추가적인 실시예에 따르면, 나노합금 조성물은 추가 첨가제를 더 포함할 수 있다. 구체적으로, 추가 첨가제는, 생리식염수, 완충제, 항상화제, 킬레이트제, 분산안정제, 안료, 염료, 노화방지제 및 방부제 중 적어도 하나를 포함할 수 있으나, 이에 제한되진 않는다. 구체적인 예를 들어, 추가 첨가제들은, Zn, Mg, K, P, Cl, Ca, I, Si, Ti, Al 등을 포함할 수 있다. 이러한 추가 첨가제는 나노합금 조성물의 유전율 변화를 야기킴으로써, 항균막(100)에서 발생되는 전자기장을 변환 또는 조정시킬 수 있다. 다시 말해, 추가첨가제를 통해 항균막(100)에서 발생되는 전자기장에 대한 조정이 가능해질 수 있다.According to a further embodiment, the nanoalloy composition may further include additional additives. Specifically, the additional additive may include, but is not limited to, at least one of physiological saline, a buffer, an antioxidant, a chelating agent, a dispersion stabilizer, a pigment, a dye, an anti-aging agent, and a preservative. For specific examples, additional additives may include Zn, Mg, K, P, Cl, Ca, I, Si, Ti, Al, and the like. These additional additives can change or adjust the electromagnetic field generated in the antimicrobial membrane 100 by causing a change in the dielectric constant of the nanoalloy composition. In other words, it may be possible to adjust the electromagnetic field generated from the antimicrobial membrane 100 through the additional additive.
일 실시예에 따르면, 나노합금 조성물은 향상된 투과율 및 열차단율을 가질 수 있다. 나노합금 조성물이 향상된 투과율 및 열차단율을 가짐에 따라, 해당 나노합금 조성물을 포함하여 구성되는 항균막(100) 또한 향상된 투과율 및 열차단율을 가질 수 있다. 항균막(100)은 예컨대, 필름의 형태로 구비되어 건물 또는 차량의 창문에 부착되어 향상된 투과율 및 열차단율을 통해 에너지 효율을 향상시키는 효과를 제공할 수 있다.According to one embodiment, the nanoalloy composition may have improved transmittance and thermal insulation rate. As the nanoalloy composition has improved transmittance and thermal barrier rate, the antimicrobial membrane 100 including the nanoalloy composition may also have improved transmittance and thermal barrier rate. The antibacterial membrane 100 may be provided in the form of, for example, a film and attached to a window of a building or vehicle to provide an effect of improving energy efficiency through improved transmittance and thermal insulation rate.
구체적으로, 나노합금 조성물은 전자기장에 의해 야기되는 표면 플라즈몬을 통해 근적외선을 반사시키고 가시광선을 투과시킴에 따라 향상된 투과율(VLT, Visible Light Transmittance) 및 열차단율(TESR, Total Sola Energy Rejection)을 갖는 것을 특징으로 할 수 있다. 표면 플라즈몬은, 금속 내의 자유전자가 집단적으로 진동하는 유사 입자를 의미한다. 자세히 설명하면, 박막층의 전자기장에 의한 표면 플라즈몬을 형성시켜 빛의 근적외선대 전자기장이 만나 표면 플라즈몬 공명(SPR, surface plasmon resonance)이 형성될 수 있다. 표면 플라즈몬 공명의 영향으로 국소적으로 매우 증가된 전기장을 발생시키게 된다. 이는 빛 에너지가 표면 플라스몬에 변환되어 금속의 나노 입자 표면에 축적된 것을 의미하며, 빛의 회절 한계보다 작은 영역에서 광 제어가 가능하도록 할 수 있다. 즉, 이러한 표면 플라즈몬 공명을 통해 열을 발생시키는 근적외선을 반사될 수 있으며, 가시광선은 투과됨에 따라, 투과율 및 열차단율을 향상될 수 있다.Specifically, the nanoalloy composition has improved transmittance (VLT, Visible Light Transmittance) and thermal rejection (TESR, Total Sola Energy Rejection) by reflecting near-infrared rays and transmitting visible rays through surface plasmons caused by electromagnetic fields. can be characterized. Surface plasmons refer to pseudo-particles in which free electrons in a metal oscillate collectively. In detail, surface plasmon is formed by the electromagnetic field of the thin film layer, and surface plasmon resonance (SPR) can be formed when the near-infrared electromagnetic field of light meets. Due to the surface plasmon resonance, a highly increased electric field is generated locally. This means that light energy is converted into surface plasmons and accumulated on the surface of metal nanoparticles, and light can be controlled in a region smaller than the diffraction limit of light. That is, near-infrared rays that generate heat may be reflected through the surface plasmon resonance, and as visible rays are transmitted, transmittance and heat rejection may be improved.
즉, 나노합금 조성물을 통해 구성되는 박막층(130)은 반자성체 성분(즉, 구리)의 재료를 포함하여 구성됨에 따라 항균 작용을 수행할 수 있으며, 스스로 전자기장을 발생시켜 항바이러스 작용을 수행하고, 그리고 향상된 투과율 및 열차단율을 제공할 수 있다. 일 실시예에서, 박막층(130)은, 구비 두께에 따라 투과율의 조정이 가능한 것을 특징으로 할 수 있다. 예컨대, 박막층(130)의 구비 두께에 클수록 투과율을 더욱 향상될 수 있다. That is, the thin film layer 130 composed of the nanoalloy composition can perform an antibacterial action as it is composed of a material of a diamagnetic component (ie, copper), generates an electromagnetic field by itself to perform an antiviral action, and It can provide improved transmittance and thermal insulation rate. In one embodiment, the thin film layer 130 may be characterized in that the transmittance can be adjusted according to the thickness of the thin film layer 130 . For example, as the thickness of the thin film layer 130 increases, transmittance may be further improved.
일 실시예에 따르면, 박막층(130)은 스퍼터링(sputtering) 또는 증착(evaporation) 방식으로 기재층(120)의 일면에 증착되는 것을 특징으로 할 수 있다. 박막층(130)은 금속에 관련한 나노합금 조성물을 통해 구성되는 것으로, 스퍼터링 공정을 통해 증착될 수 있다. 스퍼터링 공정은 진공상태에서 수행되는 증착 공정으로, 증착하고자 하는 물질(즉, 나노합금 조성물)과 막을 입힐 부분(즉, 기재층)에 전계를 가하고, 사이에 제4의 물질 상태인 플라즈마를 발생시켜 비활성 기체인 아르곤이온(Ar+)이 (-)극과 연결된 타겟(즉, 나노합금 조성물)쪽으로 이동하면서, 금속과 부딪쳐서 금속 입자가 튕겨서 나와 반대편에 있는 기재층에 쌓이게 유도하여 나노합금 조성물을 기재층(120)의 일면에 증착시키는 공정일 수 있다. 이러한 스퍼터링 방식의 공정을 통해 기재층(120)의 일면에 나노합금 조성물이 증착되어 박막층(130)이 단일 레이어 형태를 통해 형성될 수 있다.According to one embodiment, the thin film layer 130 may be characterized in that it is deposited on one surface of the base layer 120 by sputtering or evaporation. The thin film layer 130 is composed of a metal-related nanoalloy composition and may be deposited through a sputtering process. The sputtering process is a deposition process performed in a vacuum state. An electric field is applied to the material to be deposited (i.e., the nanoalloy composition) and the portion to be coated (i.e., the substrate layer), and plasma, a fourth material state, is generated between them. Argon ions (Ar+), an inert gas, move toward the target (i.e., the nanoalloy composition) connected to the (-) pole, collide with the metal, and cause the metal particles to bounce off and accumulate on the substrate layer on the opposite side, thereby forming the nanoalloy composition in the substrate layer. It may be a process of depositing on one side of (120). A nanoalloy composition is deposited on one surface of the base layer 120 through the sputtering process, so that the thin film layer 130 may be formed in a single layer form.

The nanoalloy composition can perform an antibacterial action through a trace copper action through a material of a diamagnetic component (ie, copper), an antiviral action through a self-generated electromagnetic field, and provide improved transmittance and thermal insulation rate. .
일 실시예에서 광촉매소자는, 나노합금 조성물을 통해 발생되는 전자기장을 통해 화학 반응(예컨대, 산화, 환원 반응)을 촉진시키는 것을 특징으로 할 수 있다. 다시 말해, UV 등 빛이 없는 조건에서도 광학 작용을 유도하는 광촉매역할을 수행할 수 있다. 광촉매소자는 전자기장에 의해 광촉매 반응 활성을 유도하여 항균, 항바이러스, 탈취 기능을 극대화시킬 수 있다.In one embodiment, the photocatalytic device may promote a chemical reaction (eg, oxidation or reduction reaction) through an electromagnetic field generated through the nanoalloy composition. In other words, it can act as a photocatalyst that induces an optical action even under conditions where there is no light such as UV. The photocatalytic device can maximize antibacterial, antiviral, and deodorizing functions by inducing a photocatalytic reaction activity by an electromagnetic field.
보다 구체적으로, 도 5를 참조하면, 광촉매소자란 적정 에너지 이상의 갖는 빛을 받게되면 활성산소, 수산기 라디칼(Hydroxyl Radical)을 발생시켜서 이들의 강한 산화, 환원 작용에 의해 악취물질의 분해 및 항균 작용을 발생시킬 수 있는 반도체적 성질을 갖는 물질을 의미할 수 있다. 반도체는 일정한 영역의 에너지가 가해지면 원자가 전자대(valence band)에서 전도대(conduction band)로 여기된다. 이때 전도대에서는 전자(e-)(20)들이 형성되게 되고 전자대에는 정공(h+)(30)이 형성되게 된다. 이렇게 형성된 전자(20)와 정공(30)은 강한 산화 또는 환원 작용에 의해 유해물질을 분해시키기 위한 반응을 일으키게 된다. 이와 같이, 광촉매의 특성을 갖는 소자로 이산화티탄(TiO2) 및 산화아연(ZnO)을 포함할 수 있으나, 이에 제한되진 않는다. 이산화티탄 또는 산화아연은 화학적 안정성과 반도체로서의 우수한 장점을 가질 수 있다. 예컨대, 이산화티탄은 약 3.0eV에서 이상의 에너지를 기반으로 광촉매로서의 기능을 수행할 수 있다.More specifically, referring to FIG. 5, the photocatalytic device generates active oxygen and hydroxyl radicals when receiving light having more than appropriate energy, and decomposes odorous substances and has an antibacterial action through their strong oxidation and reduction actions. It may refer to a material having semiconductor properties that can be generated. Semiconductors are excited from the valence band to the conduction band when a certain range of energy is applied. At this time, electrons (e−) 20 are formed in the conduction band and holes (h+) 30 are formed in the electron band. The electrons 20 and holes 30 thus formed cause a reaction to decompose harmful substances by a strong oxidation or reduction action. As such, elements having photocatalytic properties may include titanium dioxide (TiO 2 ) and zinc oxide (ZnO), but are not limited thereto. Titanium dioxide or zinc oxide may have chemical stability and excellent advantages as a semiconductor. For example, titanium dioxide may function as a photocatalyst based on energy above about 3.0 eV.
예컨대, 광촉매 소자인 이산화티탄은, 나노합금 조성물을 통해 발생되는 전자기장(10)에 의해 전자(20)와 정공(30)을 발생시키며, 전자와 정공 각각은 공기 중의 O2, H2O와 반응을 일으켜 표면에 수퍼옥사이드 음이온(O2-)(21)과 하이드록실기 라디칼(-OH)(31)로 된 2종 활성산소를 생성할 수 있다.For example, titanium dioxide, a photocatalytic element, generates electrons 20 and holes 30 by the electromagnetic field 10 generated through the nanoalloy composition, and each of the electrons and holes reacts with O 2 and H 2 O in the air. can generate superoxide anion (O 2 -) (21) and two types of active oxygen consisting of a hydroxyl radical (-OH) (31) on the surface.
하이드록실기 라디칼(31)은 높은 산화, 환원 전위를 가지고 있기 때문에 NOx, 휘발성 유기화합물(VOCs) 및 각종 악취 정화에 탁월할 수 있으며, 축산폐수, 오수, 공장폐수의 BOD, 색도 및 난분해성 오염물질, 환경 호르몬 등을 완벽히 제거할 수 있다. 뿐만 아니라, 하이드록실기 라디칼은 병원성 대장균, 황색포도상구균, O-157 등 각종 병원균과 박테리아를 99% 이상 살균하는 등 모든 대상물질을 산화시킬 수 있다.Since the hydroxyl radical (31) has a high oxidation and reduction potential, it can be excellent in purifying NOx, volatile organic compounds (VOCs) and various odors, and it can be excellent for livestock wastewater, sewage, factory wastewater BOD, color and recalcitrance pollution Substances, environmental hormones, etc. can be completely removed. In addition, hydroxyl radicals can oxidize all target substances, such as sterilizing over 99% of various pathogens and bacteria such as pathogenic Escherichia coli, Staphylococcus aureus, and O-157.
이러한 광촉매 소자는 태양에너지 또는 형광 빛에 의해서도 반응이 일어나며, "물체에 정착, 광분해, 재생"의 사이클에 의해 영속적인 기능을 발휘하므로 경제적일 수 있다. 또한, 반응 후의 부산물은 물과 CO2로 인체 및 환경에 무해한 물질이기 때문에 다양한 분야에 적용이 가능할 수 있다.Such a photocatalytic device can be economical because it reacts even with solar energy or fluorescent light, and exhibits a permanent function through a cycle of “fixation on an object, photolysis, and regeneration”. In addition, since the by-products after the reaction are water and CO 2 that are harmless to the human body and the environment, they can be applied to various fields.
일 실시예에 따르면, 코팅층(140)은 전체 용액 대비 용질의 농도가 0.01 내지 2wt%인 나노합금 조성물을 포함하여 구성될 수 있다. 이 경우, 코팅층(140)은 나노합금 조성물 100 중량부 대비 광촉매소자를 5 내지 500 중량부로 포함하여 구성되는 것을 특징으로 할 수 있다. 즉, 코팅층(140)은 용질(예컨대, 구리-철 합금에 관련한 나노분말)의 농도가 0.01 내지 2wt%인 나노합금 조성물을 통해 구성되며, 나노합금 조성물 대비 광촉매소자의 구비 비율은 1 : 0.2~500일 수 있다. 상술한 바와 같은, 코팅층(140)을 구성하는 나노합금 조성물 내에서의 용질의 농도 및 나노합금 조성물 대비 광촉매소자의 구비 비율은, 광촉매 기능을 극대화함으로써, 탈취, 투과율, 열차단율을 향상시키는 위한 최적의 비율일 수 있다.According to one embodiment, the coating layer 140 may include a nanoalloy composition having a solute concentration of 0.01 to 2 wt% relative to the total solution. In this case, the coating layer 140 may be characterized by comprising 5 to 500 parts by weight of the photocatalytic element based on 100 parts by weight of the nanoalloy composition. That is, the coating layer 140 is composed of a nanoalloy composition having a concentration of solute (eg, nanopowder related to a copper-iron alloy) of 0.01 to 2wt%, and the ratio of the photocatalytic element to the nanoalloy composition is 1:0.2 to 1:0.2. may be 500. As described above, the concentration of the solute in the nanoalloy composition constituting the coating layer 140 and the ratio of the photocatalytic element to the nanoalloy composition are optimal for improving deodorization, transmittance, and thermal insulation rate by maximizing the photocatalytic function. may be a ratio of
일 실시예에서, 코팅층(140)은 습식 코팅을 통해 박막층(130)의 일면에 코팅되며, 미리 정해진 두께 및 표면경도를 통해 구성될 수 있다. 예를 들어, 미리 정해진 두께는 1~10㎛일 수 있으며, 미리 정해진 표면 경도는 2~5H(Hardness)일 수 있다. 이 경우, 미리 정해진 두께 및 표면경도는 표면 플라즈몬 현상에 의해 광촉매 기능을 극대화시킴과 동시에, 표면 보호기능을 향상시키기 위한 최적 값일 수 있다. 전술한 코팅층의 두께 및 표면 경도에 대한 구체적인 수치적 기재는 예시일 뿐, 본 발명은 이에 제한되지 않는다. 구체적으로, 코팅층(140)은 박막층(130)을 기재로 하여 액체 상태의 조합물(즉, 나노합금 조성물과 광촉매 소자(예컨대, 이산화티탄)의 조합)을 롤투롤(Roll-to-Roll) 형태로 도포하여 진행함에 따라 생성될 수 있다. 예컨대, 박막층의 권출(언와인딩, Unwinding), 박막층의 표면전처리(Pre-treatment), 코팅(Coating), 건조(Drying), 권취(리와인딩, Rewinding) 등의 과정을 통해 코팅층(140)이 형성될 수 있다. 이 경우, 습식 코팅은, 그라비아 코팅, 마이크로 그라비아 코팅 또는 콤마 코팅 중 적어도 하나를 포함할 수 있으나, 이에 제한되지 않는다. 형성된 코팅층(140)은 나노합금 조성물과 광촉매 소자의 혼합에 의해 생성된 것으로, 금속의 재질을 포함하고 있어, 표면 강도가 우수할 수 있다. 다시 말해, 항균막(100)의 표피에 형성되는 코팅층(140)은 표면 보호 기능을 가질 수 있다.In one embodiment, the coating layer 140 is coated on one surface of the thin film layer 130 through wet coating, and may be configured through a predetermined thickness and surface hardness. For example, the predetermined thickness may be 1 to 10 μm, and the predetermined surface hardness may be 2 to 5H (Hardness). In this case, the predetermined thickness and surface hardness may be optimal values for maximizing the photocatalytic function and improving the surface protection function by the surface plasmon phenomenon. The specific numerical description of the thickness and surface hardness of the above-described coating layer is only an example, and the present invention is not limited thereto. Specifically, the coating layer 140 is a combination of a liquid state (ie, a combination of a nanoalloy composition and a photocatalytic element (eg, titanium dioxide)) using the thin film layer 130 as a base in a roll-to-roll form. It can be created as it is applied and progressed. For example, the coating layer 140 is formed through processes such as unwinding (unwinding) of the thin film layer, pre-treatment of the surface of the thin film layer, coating, drying, and winding (rewinding). It can be. In this case, the wet coating may include at least one of gravure coating, micro gravure coating, or comma coating, but is not limited thereto. The formed coating layer 140 is produced by mixing the nanoalloy composition and the photocatalytic element, and may have excellent surface strength because it includes a metal material. In other words, the coating layer 140 formed on the epidermis of the antimicrobial membrane 100 may have a surface protection function.
또한, 코팅층(140)의 광촉매 소자는 나노합금 조성물을 통해 야기되는 전자기장을 통해 화학 반응을 촉진시킴에 따라, 항균, 항바이러스, 탈취 기능을 극대화시킬 수 있다. 예컨대, 도 6의 (a) 도시된 바와 같이, 구리가 도핑(doping)된 광촉매소자(300)의 경우, 구리가 도핑되지 않은 광촉매 소자 보다 밴드갭이 감소함을 확인할 수 있다. 즉, 나노합금 조성물을 통해 광촉매 소자를 도핑하는 경우(즉, 구리가 dope된 이산화티탄)은, 광촉매 소자(즉, TiO2) 즉, 구리가 도핑되지 않은 광촉매 소자(310)의 밴드갭(311) 보다 감소된 밴드갭(301)을 가질 수 있다. 밴드갭 감소는 결과적으로, 전기적으로 전도성이 더 커짐을 의미할 수 있으며, 이에 따라 항바이러스 및 탈취 효과가 극대화될 수 있다. 또한, 도 6의 (b) 도시된 바와 같이, 광촉매 소자와 나노합금 조성물 간의 혼합물(즉, 구리가 도핑된 이산화티탄)은, 다중전자전달 현상(TiO2, Cu, Cu+, Cu2+) 이용한 효율 향상을 야기시킬 수 있다. 감소된 밴드갭으로 인해 가시광(visible light) 영역의 다중전자 전달을 위한 충분한 전자 생성이 가능함에 따라, 가시광을 비교적 효과적으로 흡수하여 빠르고 유기적인 산화(organic oxidation), 환원 반응을 야기시킬 수 있다. 다시 말해, 가시광 조사 하에서 계면전하이동전이(IFCT, Interfacial Charge Transfer)에 의하여 가전자대역에 있는 전자의 환원 반응이 촉진될 수 있다. 이에 따라, 가전자대역의 정공을 광촉매반응에 활용할 수 있다. 이러한, 코팅층(140)은 UV 등 빛이 없는 조건에서도 발생되는 전자기장을 통해 광학 작용을 유도하는 광촉매 역할을 수행하여 항균, 항바이러스 및 탈취 효과를 극대화시킬 수 있다.In addition, as the photocatalytic element of the coating layer 140 promotes a chemical reaction through an electromagnetic field generated through the nanoalloy composition, antibacterial, antiviral, and deodorizing functions can be maximized. For example, as shown in (a) of FIG. 6 , in the case of the photocatalytic device 300 doped with copper, it can be confirmed that the band gap is reduced compared to the photocatalytic device without copper doping. That is, when the photocatalytic element is doped through the nanoalloy composition (ie, copper-doped titanium dioxide), the photocatalytic element (ie, TiO 2 ), that is, the band gap 311 of the photocatalytic element 310 that is not doped with copper. ) may have a reduced band gap 301. As a result, a decrease in band gap may mean that electrical conductivity is increased, and thus antiviral and deodorizing effects may be maximized. In addition, as shown in (b) of FIG. 6, the mixture between the photocatalytic element and the nanoalloy composition (ie, titanium dioxide doped with copper) improves efficiency using multiple electron transfer phenomena (TiO2, Cu, Cu+, Cu2+). can cause As enough electrons can be generated for multiple electron transfer in the visible light region due to the reduced band gap, visible light can be relatively effectively absorbed to cause rapid organic oxidation and reduction reactions. In other words, the reduction reaction of electrons in the valence band may be promoted by Interfacial Charge Transfer (IFCT) under visible light irradiation. Accordingly, holes in the valence band can be utilized for the photocatalytic reaction. The coating layer 140 may maximize antibacterial, antiviral, and deodorizing effects by serving as a photocatalyst that induces an optical action through an electromagnetic field generated even under conditions where there is no light such as UV.
전술한 바와 같이, 항균막(100)은 항균, 항바이러스 및 탈취 효과를 제공할 수 있다. 정리하면, 도 7에 도시된 바와 같이, 항균막(100)은 하이드록실기 라디칼의 높은 산화, 환원 전위에 기반한, 휘발성 유기화합물(VOCs) 질소산화물(NOx), 황산화물(SOx) 및 포름알데히드와 같은 유해물질 제거를 통해 공기정화 효과를 제공할 수 있다. 또한, 항균막(100)은 아세트알데히드, 암모니아, 황화수소 등의 악취를 흡착분해여 탈취 효과를 제공할 수 있다. 또한, 항균막(100)은 반자성체 성분의 재료(즉, 구리)를 통해 미량동 작용을 통해 살모넬라, 0157, 황색포도사상균, 대장균, 곰팡이 등의 살균 또는 부패방지에 관한 항균 효과를 제공할 수 있다. 또한, 항균막(100)은 빛을 받으면 물을 끌어당기는 성질을 활용하여 self-cleaning 효과를 제공하는 등 친수 효과를 제공할 수 있다. 또한, 항균막(100)은 유기물질 분해를 통해 표면에 오염의 방지하는 효과를 제공할 수 있다.As described above, the antimicrobial membrane 100 may provide antibacterial, antiviral and deodorizing effects. In summary, as shown in FIG. 7, the antimicrobial membrane 100 is based on the high oxidation and reduction potential of hydroxyl radicals, volatile organic compounds (VOCs) nitrogen oxides (NOx), sulfur oxides (SOx) and formaldehyde It can provide an air purification effect through the removal of harmful substances such as In addition, the antibacterial membrane 100 may provide a deodorizing effect by adsorbing and decomposing odors such as acetaldehyde, ammonia, and hydrogen sulfide. In addition, the antimicrobial film 100 can provide an antibacterial effect related to sterilization or anti-corruption of Salmonella, 0157, Staphylococcus aureus, Escherichia coli, mold, etc. . In addition, the antibacterial film 100 may provide a hydrophilic effect such as providing a self-cleaning effect by utilizing a property of attracting water upon receiving light. In addition, the antimicrobial film 100 may provide an effect of preventing contamination on the surface through decomposition of organic substances.
이러한 항균막(100)은 대상 부재에 도포, 접착 또는 결속되어 일부 층을 형성함으로써, 항바이러스 및 항균 효과를 구현할 수 있다. 이 경우, 대상 부재는 모든 물품을 의미할 수 있다. 예를 들어, 대상 부재는, 부직포, 섬유시트, 액정, 디스플레이, 모니터, 키보드, 종이, 금속 등을 포함할 수 있으나, 이에 제한되지 않는다.The antibacterial film 100 may implement antiviral and antibacterial effects by forming a partial layer by applying, adhering, or binding to a target member. In this case, the target member may mean all articles. For example, the target member may include non-woven fabric, fiber sheet, liquid crystal, display, monitor, keyboard, paper, metal, etc., but is not limited thereto.
예를 들어, 항균막(100)은 사용자의 피부와 접하는 제품을 대상 부재로 하여 접착되어 구비될 수 있다. 구체적인 예를 들어, 항균막(100)은 기저귀, 물티슈, 크린징 티슈, 생리대, 깔창 등의 사람 피부와 접하는 대상 부재에 접촉하여 구성될 수 있다. 종래의 피부와 접하는 제품은, 곰팡이 또는 세균이 발생하는 것을 방지하기 위하여 방부제가 포함될 수 있다. 이러한 방부제는 휘발성을 가진 알코올계 화학물질이며 특유의 냄새가 발생할 수 있다. 따라서 상기 방부제 특유의 냄새를 제거하기 위한 별도의 인공향을 사용하고 있으며, 이 경우 사용자의 신체에도 좋지 않은 영향을 미칠 수 있다. 다만, 항균막(100)은 별도의 화학물질을 포함하지 않으므로, 사용자의 신체 건강에도 효과적이며, 항균, 항바이러스 및 탈취 효과를 제공할 수 있다.For example, the antibacterial film 100 may be provided by being adhered to a product in contact with the user's skin as a target member. For example, the antibacterial membrane 100 may be configured by contacting a target member such as a diaper, wet tissue, cleansing tissue, sanitary napkin, or insole that comes in contact with human skin. Conventional skin contact products may contain preservatives to prevent mold or bacteria from occurring. These preservatives are alcohol-based chemicals with volatility and may generate a characteristic odor. Therefore, a separate artificial fragrance is used to remove the peculiar smell of the preservative, and in this case, it may adversely affect the user's body. However, since the antimicrobial film 100 does not contain a separate chemical substance, it is effective for the user's physical health and can provide antibacterial, antiviral and deodorizing effects.
다른 예를 들어, 항균막(100)은 필터를 대상 부재로 하여 접착되어 구비될 수 있다. 즉, 항균막(100)은 복합공조기(예컨대, 냉난방기, 전열교환기, 가습기, 공기청정기 등)의 필터 또는 사용자가 착용하는 마스크의 필터의 일면에 부착되어 구비될 수 있다. 이 경우, 세균의 발생처와 서식처가 되어 실내 공간의 2차 오염원이 될 수 있는 필터에 대하여 항균, 항바이러스 및 탈취 효과를 제공할 수 있다.For another example, the antimicrobial membrane 100 may be provided by being adhered to a filter as a target member. That is, the antibacterial film 100 may be provided by being attached to one surface of a filter of a combined air conditioner (eg, air conditioner, total heat exchanger, humidifier, air purifier, etc.) or a filter of a mask worn by a user. In this case, antibacterial, antiviral, and deodorizing effects can be provided to the filter, which can become a source and habitat of bacteria and become a secondary pollutant in the indoor space.
또 다른 예를 들어, 항균막(100)은 건물 또는 차량의 창문을 대상 부재로 하여 접착되어 구비될 수 있다. 이 경우, 창문에 대한 점착은 점착층(110)을 통해 이뤄질 수 있다. For another example, the antimicrobial film 100 may be provided by being adhered to a window of a building or vehicle as a target member. In this case, adhesion to the window may be achieved through the adhesive layer 110 .
일 실시예에 따르면, 항균막(100)은 향상된 투과율 및 열차단율을 가질 수 있다. 나노합금 조성물이 향상된 투과율 및 열차단율을 갖는 경우, 해당 나노합금 조성물을 포함하여 구성되는 항균막(100)은 필름의 형태로 구비되어 건물 또는 차량의 창문에 부착되어 에너지의 효율을 향상시킬 수 있다.According to one embodiment, the antimicrobial membrane 100 may have improved transmittance and thermal barrier rate. When the nanoalloy composition has improved transmittance and thermal insulation rate, the antimicrobial membrane 100 comprising the nanoalloy composition is provided in the form of a film and is attached to a window of a building or vehicle to improve energy efficiency. .
구체적으로, 나노합금 조성물을 포함하는 항균막(100)이 윈도우 필름 형태로 구성되는 경우, 가시광선 투과율 및 열차단율을 향상시킬 수 있으며, 필름의 제조 공정상의 편의성을 제공하고 그리고, 필름의 두께를 최소화하는 효과를 제공할 수 있다. 항균막(100)이 윈도우 필름 형태로 구비됨에 따라 제공될 수 있는 다양한 효과에 대한 설명은, 도 8 및 도 9를 참조하여 이하에서 후술하도록 한다.Specifically, when the antimicrobial membrane 100 including the nanoalloy composition is configured in the form of a window film, it is possible to improve visible light transmittance and heat shielding rate, provide convenience in the manufacturing process of the film, and reduce the thickness of the film. It can provide a minimizing effect. A description of various effects that can be provided as the antimicrobial membrane 100 is provided in the form of a window film will be described below with reference to FIGS. 8 and 9 .
도 8의 (a)는 종래의 일반적인 윈도우 필름의 예시적인 단면도를 도시하며, 도 8의 (b)는 본 발명의 항균막(100)의 예시적인 단면도를 도시한다. 또한, 도 9는 종래의 일반적인 윈도우 필름 본 발명의 항균막 각각에 관련한 에너지 효율을 설명하기 위한 예시도를 도시한다.Figure 8 (a) shows an exemplary cross-sectional view of a conventional general window film, Figure 8 (b) shows an exemplary cross-sectional view of the antimicrobial film 100 of the present invention. In addition, Figure 9 shows an exemplary diagram for explaining the energy efficiency related to each of the antimicrobial membranes of the conventional general window film of the present invention.
종래의 윈도우 필름(101)은, 도 8의 (a)에 도시된 바와 같이, 제1점착층(111), 제1기재층(121), 제1박막층(131) 및 제1코팅층(141)을 포함할 수 있다. 이 경우, 제1점착층(111)은 본원 발명의 점착층(110)에 대응하는 하는 것으로, 점착제를 통한 습식 코팅을 통해 구성될 수 있다.As shown in (a) of FIG. 8, the conventional window film 101 includes a first adhesive layer 111, a first substrate layer 121, a first thin film layer 131, and a first coating layer 141. can include In this case, the first adhesive layer 111 corresponds to the adhesive layer 110 of the present invention and may be formed through wet coating using an adhesive.
또한, 일 실시예에 따르면, 종래의 윈도우 필름의 제1기재층(121)과 항균막(100)의 기재층은 동일한 소재를 통해 구성될 수 있다. 예컨대, 각 필름의 기재층은 PET로 구성될 수 있으나, 필수적인 것은 아니다.Also, according to one embodiment, the first base layer 121 of the conventional window film and the base layer of the antimicrobial membrane 100 may be made of the same material. For example, the base layer of each film may be composed of PET, but this is not essential.
다만, 이 경우, 본 발명의 기재층(120)은 1PLY(즉, 한 겹)을 통해 구성되는 것을 특징으로 할 수 있다. 일반적인 윈도우 필름의 기재층(즉, 제1기재층)의 경우, 열을 견디기 위해 2PLY(즉, 두 겹) 이상으로 구성될 수 있다. 반면, 본 발명의 항균막은 향상된 투과율 및 열차단율을 가짐에 따라 1PLY를 통해 구성될 수 있다. 이는, 시공 상의 편의성을 제공할 뿐만 아니라, 전반적인 막 또는 필름의 두께를 최소화한다는 장점이 있다.However, in this case, the base layer 120 of the present invention may be characterized in that it is configured through 1PLY (ie, one layer). In the case of a base layer (ie, the first base layer) of a general window film, it may be composed of 2PLY (ie, two layers) or more to withstand heat. On the other hand, the antimicrobial membrane of the present invention can be configured through 1PLY as it has improved transmittance and thermal barrier rate. This has the advantage of not only providing convenience in construction, but also minimizing the overall thickness of the film or film.
또한, 본 발명의 항균막(100)은 종래의 일반적인 윈도우 필름(101) 보다 얇은 박막층 형성하는 것을 특징으로 할 수 있다. 구체적으로, 항균막(100)의 박막층(130)은 단일 레이어로 구성됨에 따라 종래의 일반적인 윈도우 필름(101)의 제1박막층(131) 보다 얇은 두께를 통해 구비될 수 있다.In addition, the antimicrobial film 100 of the present invention may be characterized by forming a thin film layer thinner than the conventional general window film 101. Specifically, since the thin film layer 130 of the antimicrobial film 100 is composed of a single layer, it may be provided through a thickness thinner than that of the first thin film layer 131 of the conventional general window film 101.
종래의 일반적인 윈도우 필름(101)의 제1박막층(131)은 복수의 소재를 통한 증착을 기반으로 다중 레이어(Multi layer)를 형성하는 것을 특징으로 하는 반면, 본 발명의 항균막(100)은, 기재층(120)의 일면에 액체 상태의 나노합금 조성물이 스퍼터링 방식의 공정을 통해 단일 레이어 형태로 박막층(130)을 형성될 수 있다. 나노합금 조성물은 전자기장에 의해 야기되는 표면 플라즈몬을 통해 근적외선을 반사시키고 가시광선을 투과시킴에 따라 향상된 투과율 및 열차단율을 갖는 것을 특징으로 할 수 있다. 표면 플라즈몬은, 금속 내의 자유전자가 집단적으로 진동하는 유사 입자를 의미한다. 자세히 설명하면, 박막층의 전자기장에 의한 표면 플라즈몬을 형성시켜 빛의 근적외선대 전자기장이 만나 표면 플라즈몬 공명(SPR, surface plasmon resonance)이 형성될 수 있다. 표면 플라즈몬 공명의 영향으로 국소적으로 매우 증가된 전기장을 발생시키게 된다. 이는 빛 에너지가 표면 플라스몬에 변환되어 금속의 나노 입자 표면에 축적된 것을 의미하며, 빛의 회절 한계보다 작은 영역에서 광 제어가 가능하도록 할 수 있다. 즉, 이러한 표면 플라즈몬 공명을 통해 열을 발생시키는 근적외선을 반사될 수 있으며, 가시광선은 투과됨에 따라, 투과율 및 열차단율을 향상될 수 있다.While the first thin film layer 131 of the conventional general window film 101 is characterized by forming multi-layers based on deposition through a plurality of materials, the antimicrobial film 100 of the present invention, The thin film layer 130 may be formed in a single layer form on one side of the base layer 120 through a sputtering process of a nano-alloy composition in a liquid state. The nanoalloy composition may be characterized as having improved transmittance and heat rejection as it reflects near infrared rays and transmits visible rays through surface plasmons caused by electromagnetic fields. Surface plasmons refer to pseudo-particles in which free electrons in a metal oscillate collectively. In detail, surface plasmon is formed by the electromagnetic field of the thin film layer, and surface plasmon resonance (SPR) can be formed when the near-infrared electromagnetic field of light meets. Due to the surface plasmon resonance, a highly increased electric field is generated locally. This means that light energy is converted into surface plasmons and accumulated on the surface of metal nanoparticles, and light can be controlled in a region smaller than the diffraction limit of light. That is, near-infrared rays that generate heat may be reflected through the surface plasmon resonance, and as visible rays are transmitted, transmittance and heat rejection may be improved.
예컨대, 종래의 윈도우 필름(101)의 경우, 단열성 또는 내구성을 위하여 TiO2를 증착시켜 하나의 레이어를 형성하고, SiO2를 통해 다음 레이어를 증착시키고, Ag를 통해 또 다음 레이어를 증착하는 등 복수의 소재를 순차적으로 증착하여 다중 레이어를 형성할 수 있다. 반면, 본 발명의 항균막(100)은 반자성체 성분과 강자성체 성분의 합금을 통해 야기되는 나노합금 조성물의 특성으로 인해 해당 나노합금 조성물을 통해 하나의 레이어 형성함으로써, 기재층(120)을 구성할 수 있으므로, 두께 측면에서 유리할 수 있다.For example, in the case of the conventional window film 101, TiO 2 is deposited to form one layer, SiO 2 is deposited on the next layer, Ag is deposited on the next layer, and a plurality of materials are deposited for insulation or durability. may be sequentially deposited to form multiple layers. On the other hand, the antimicrobial membrane 100 of the present invention can constitute the base layer 120 by forming one layer through the nanoalloy composition due to the characteristics of the nanoalloy composition caused by the alloy of the diamagnetic component and the ferromagnetic component. Therefore, it may be advantageous in terms of thickness.
또한, 본 발명의 항균막(100)의 코팅층(140)은 액체 상태의 조합물(즉, 나노합금 조성물과 광촉매 소자(예컨대, 이산화티탄)의 조합)을 롤투롤(Roll-to-Roll) 형태로 도포되는 습식 코팅을 통해 형성될 수 있다. 즉, 코팅층(140)은 일반적인 제1코팅층(141)과 달리 나노합금 조성물과 광촉매 소자를 포함하여 구성됨에 따라, 전자기장을 발생시키고, 해당 전자기장을 통해 광학 작용을 유도하는 등 항균, 항바이러스 및 탈취 효과를 극대화시킬 수 있다. 다시 말해, 코팅층(140)은 UV 등 빛이 없는 조건에서도 광학 작용을 유도하는 광촉매 역할을 수행하여 항균, 항바이러스 및 탈취 효과를 극대화시킬 수 있다.In addition, the coating layer 140 of the antimicrobial membrane 100 of the present invention is a combination of a liquid state (ie, a combination of a nanoalloy composition and a photocatalytic element (eg, titanium dioxide)) in a roll-to-roll form.

In addition, the conventional general window film 101 causes discoloration and deterioration over time, but the antimicrobial film 100 of the present invention may have a low degree of deterioration through a heat reflection mechanism.
또한, 종래의 일반적인 윈도우 필름(101)은 항균, 항바이러스 및 탈취 등 별도의 추가적 기능을 제공하지 못하는 반면, 본 발명의 항균막(100)은 전자기장을 통한 항바이러스 효과, 반자성체 성분의 재료(예컨대, 구리)를 통한 항균 효과 및 높은 산화, 환원 전위에 기반한 탈취 효과 등을 추가적으로 제공할 수 있다.In addition, the conventional general window film 101 does not provide additional functions such as antibacterial, antiviral, and deodorizing, whereas the antibacterial film 100 of the present invention has an antiviral effect through an electromagnetic field, a material of a diamagnetic component (such as , copper) can provide additional antibacterial effects and deodorizing effects based on high oxidation and reduction potentials.
