Description

다기능성 망 및 이의 제조방법Multifunctional network and its manufacturing method
본 출원은 다기능성 망 및 이의 제조방법에 관한 것으로서, 보다 상세하게는 촉매를 이용하여, 다기능성 망의 메쉬에 나노와이어를 부착한 다기능성 망 및 이의 제조방법에 관한 것이다.The present application relates to a multifunctional network and a method for manufacturing the same, and more particularly, to a multifunctional network and a method for producing the nanowire attached to the mesh of the multifunctional network using a catalyst.
망은 메쉬타입의 기재로서, 네트 또는 스크린으로 지칭될 수 있으며, 다양한 용도로 사용되고 있다. 방충망, 공기정화필터용 스크린, 구조물의 강성 증진을 위한 충진망, 외부충격으로부터 충격을 흡수하여, 자재를 보호하기 위한 충격흡수망, 전자기파 차폐를 위한 EMI Shielding 재료, 전극소재 등 다양한 분야에 적용된다.The net is a mesh type substrate, which may be referred to as a net or a screen, and is used for various purposes. It is applied to various fields such as insect screens, screens for air purification filters, packing networks for enhancing the rigidity of structures, shock absorbing nets to protect materials by absorbing shocks from external shocks, EMI shielding materials for shielding electromagnetic waves, and electrode materials. .
이러한 분야 중 방충망에 대한 수요도 현재 상당히 높다. 건물에 설치된 창은 실내에서 실외를 관망할 수 있도록 하고, 실내에 자연채광이 이루어지도록 하는 기능 외에도 오염된 실내의 공기를 환기시켜 주기 위한 것으로, 이러한 창은 일정한 크기의 창틀 프레임에 미닫이 또는 여닫이 형태로 설치되고, 실내공기를 환기시킬 경우에는 창문을 개방시키게 되는데, 이 경우 개방된 창문을 통해 짧은 시간 내에 실내공기를 환기시킬 수 있다.Among these areas, the demand for insect screens is also quite high at present. In addition to the ability to view the indoors and outdoors in the room, and to provide natural light to the indoors, the windows installed in the building are used to ventilate the contaminated indoor air. When installed, and to ventilate the indoor air to open the window, in this case through the open window can be ventilated indoor air in a short time.
하지만, 환기가 이루어지는 동안 열려진 창문을 통해, 파리나 모기, 나방과 같은 벌레나 해충이 실내로 들어올 수 있다. 이를 방지하기 위하여, 방충망을 설치한다. 방충망은 일반적으로 방충망은 파리나 모기, 나방과 같은 벌레나 해충이 실내로 들어오지 못하도록 창문이나 출입문 등에 설치하는 그물을 말한다. 이러한 방충망은 나일론과 같은 합성수지, 그라스 화이바(유리섬유), 금속 등과 같은 다양한 재질로 제조된다.However, through ventilation, open windows can allow insects and pests such as flies, mosquitoes and moths to enter the room. To prevent this, install a screen. Insect screens are generally nets that are installed on windows or doors to prevent insects and insects such as flies, mosquitoes and moths from entering the room. These screens are made of various materials such as synthetic resins such as nylon, glass fibers (glass fibers), and metals.
통상적인 방충망은 가로와 세로 방향으로 와이어가 일정간격으로 배열되어 일정 크기의 격자가 형성된 메쉬망으로 형성되며, 메쉬망에 형성된 통공은 벌레나 해충이 통과하지 못할 정도의 크기를 갖는다.Conventional insect screen is a wire mesh is formed at a predetermined interval in the horizontal and vertical directions are formed as a mesh mesh having a certain size, the through-holes formed in the mesh network has a size enough to pass through the bugs or pests.
그러나 종래의 기술에 따른 방충망은 통공의 크기보다 작은 크기의 황사 먼지나 꽃가루, 미세 먼지 등을 차단하는 데에는 부적합하다.However, the insect screen according to the prior art is not suitable for blocking yellow dust, pollen, fine dust and the like smaller than the size of the through-holes.
미세먼지, 외부로부터의 소음, 매연, 스모그, 황사 또는 꽃가루가 여과 없이 실내로 유입되어 실내공기를 오염시키는 문제가 있고, 겨울철에 창문을 열어 환기를 시킬경우에는 차가운 실외공기가 실내로 유입되어 실내온도를 떨어뜨리고, 이로 인해 떨어진 실내온도를 상승시키기 위해 난방장치를 가동시킴에 따른 추가적인 에너지 손실이 발생하는 문제가 있다.Fine dust, noise from the outside, soot, smog, yellow dust or pollen enters the room without filtration and contaminates the indoor air.In case of opening the window in winter to ventilate, the cold outdoor air flows into the room. There is a problem in that an additional energy loss occurs by lowering the temperature, thereby causing the heating device to increase the room temperature.
이러한 문제점을 해결하기 위하여, 몇가지 제안된 기술이 있었으며, 그 중 하나로서, 대한민국 등록특허 10-1598756에서 '미세먼지 차단용 필터'를 개시하고 있으나, 이 기술은 탈부착이 가능한 필터를 방충막에 부착하는 것으로서, 장치를 추가적으로 부착하여야 하는 번거로움이 존재한다.In order to solve this problem, there have been some proposed techniques, and as one of them, Korean Patent No. 10-1598756 discloses a 'dust filter for fine dust', but this technique attaches a detachable filter to the screen. There is a hassle to additionally attach the device.
최근에는 황사 먼지와 같은 미세 오염물질을 차단할 수 있는 환경방충망이 제안되고 있다. 그러나, 이와 같은 환경방충망은 해충의 침입차단에는 효과를 발휘할 수 있으나 여전히 초미세먼지를 제거하는 데는 한계가 있다.Recently, environmental insect screens that can block fine contaminants such as yellow dust have been proposed. However, such an environmental insect insect net can exert an effect on blocking the infestation of pests, but there is still a limit to remove ultrafine dust.

본 출원의 상세한 설명을 위하여, 도 1을 포함하여, 본 출원을 설명한다. 도 1 내지 도 3에 도시한 바와 같이, 본 출원의 일 실시예에 따른 방충망(1)은 메쉬 부재(10), 메쉬 부재(10)의 표면에 부착된 촉매부(20) 및 촉매부(20)에 부착된 나노와이어(30)를 포함한다.For detailed description of the present application, the present application will be described, including FIG. 1. As shown in Figures 1 to 3, the insect screen 1 according to an embodiment of the present application is the mesh member 10, the catalyst portion 20 and the catalyst portion 20 attached to the surface of the mesh member 10 Nanowires 30 attached thereto).
메쉬 부재(10)는 그물망과 같은 구조를 갖는 구조체로써, 통기성이 우수한 구조체를 의미한다. 다만, 이에 한정되는 것은 아니다. 도 1 내지 3에는 단면이 정사각형으로 도시하였으나, 이에 한정되는 것은 아니다.The mesh member 10 is a structure having a structure such as a net, and means a structure having excellent breathability. However, the present invention is not limited thereto. 1 to 3, the cross section is shown as a square, but is not limited thereto.
또한, 메쉬 부재(10)의 격자의 평균 크기는 0.5 내지 5.0 mm인 것이 바람직하다. 다만, 이에 한정되는 것은 아니다. 격자의 평균 크기가 크면 통기성이 우수하나, 미세 먼지나 초미세 먼지 또한 용이하게 통과할 수 있다.Moreover, it is preferable that the average size of the grating | lattices of the mesh member 10 is 0.5-5.0 mm. However, the present invention is not limited thereto. A large average size of the grating provides good ventilation, but fine dust and ultra-fine dust can also pass through easily.
또한, 다양한 소재를 포함하는 메쉬 부재가 본 출원에 적용될 수 있다. 다만, 메쉬 부재(10)는 금속재 및 폴리머재로 이루어진 그룹으로부터 선택된 적어도 하나를 포함하는 것이 바람직하다. 예시로서, 스테인레스 스틸 및 PET를 포함한다.In addition, a mesh member including various materials may be applied to the present application. However, the mesh member 10 preferably includes at least one selected from the group consisting of metal materials and polymer materials. By way of example, stainless steel and PET are included.
촉매부(20)는 메쉬 부재(10)에 부착된다. 도 3에 도시한 촉매부(20)는 하나의 예시일 뿐, 다양한 형태로 메쉬 부재(10)에 부착될 수 있다(도 2에는 촉매부 미도시). 후술하는 나노와이어(30)가 메쉬 부재(10)에 직접적으로 부착되기 어려운 경우가 많다. 촉매부(20)는 나노와이어(30)가 성장하는 개시점이 될 수 있다.The catalyst unit 20 is attached to the mesh member 10. The catalyst unit 20 shown in FIG. 3 is just one example, and may be attached to the mesh member 10 in various forms (not shown in FIG. 2). It is often difficult for the nanowire 30 to be described later to adhere directly to the mesh member 10. The catalyst unit 20 may be a starting point at which the nanowires 30 grow.
또한, 촉매부(20)는 나노와이어(30)를 성장시킬 수 있는 소재라면 그 종류를 특별히 한정하는 것은 아니지만 전이금속(transition metal) 및 귀금속(noble metal) 및 이들의 산화물로 이루어진 그룹으로부터 선택된 적어도 하나를 포함하는 것이 바람직하다.In addition, the catalyst 20 is not particularly limited as long as it is a material capable of growing the nanowire 30, but at least selected from the group consisting of transition metals and noble metals and oxides thereof. It is preferable to include one.
이러한 예시로서, Sc, V, Cr, Mn, Fe, Co, Ni, Cu, Y, Nb, Mo, Ru, Rh, Pd, Ag, Cd, Hf, Ta, Re, Os, Ir, Pt 및 Au로 이루어진 군에서 선택되는 적어도 하나를 포함할 수 있다.By way of example, Sc, V, Cr, Mn, Fe, Co, Ni, Cu, Y, Nb, Mo, Ru, Rh, Pd, Ag, Cd, Hf, Ta, Re, Os, Ir, Pt and Au It may include at least one selected from the group consisting of.

Through the size of this range, the nanowire 30 and the mesh member 10 can be firmly adhered. If the diameter is smaller than 2 nm, when the electrostatic attraction is applied when the nanowire-grown catalyst is attached to the fiber in the process described below, the trapping efficiency to the fiber may be drastically reduced, and the diameter of the catalyst portion is larger than 200 nm. In this case, nanowires may not grow well, or only coarse nanowires having a diameter of a tube larger than 200 nm may be generated and may not be suitable for application to insect screens.

The aerosol catalyst deposition method and the dip coating method are not particularly limited. However, the conditions or processes may be limited to the purpose of adhering the catalyst unit 20 to the mesh member 10 as intended in the present application. There is a number.
나노와이어(30)는 촉매부(20)에 부착된다. 도 2 및 도 3에 도시한 나노와이어(30)는 하나의 예시일 뿐, 다양한 형태로 촉매부(20)에 부착될 수 있다. 즉, 나노와이어의 제1 단부는 촉매부(20)에 부착되어 고정된다. 그러나, 반대쪽 단부인 제2 단부는 유동할 수 있어, 나노와이어(30)가 외부의 힘에 의하여 유연한 움직임을 갖을 수 있다.The nanowires 30 are attached to the catalyst unit 20. The nanowires 30 shown in FIGS. 2 and 3 are just examples, and may be attached to the catalyst unit 20 in various forms. That is, the first end of the nanowires is attached to and fixed to the catalyst unit 20. However, the second end, which is the opposite end, may flow, such that the nanowires 30 may have flexible movement by external forces.

In addition, the nanowires 30 may include Ag, Cu, C, Si, Ag 2 O, CuO, SiO 2 , TiO 2 , ZnO, WO 3 , MgO, Ti-MgO, Zn-MgO, W-MgO, and alloys thereof. At least one selected from the group consisting of tissues.
또한, 나노와이어(30)의 평균 직경은 5 내지 500 nm이고, 평균 길이는 0.5 내지 500 ㎛인 이다.In addition, the average diameter of the nanowire 30 is 5 to 500 nm, the average length is 0.5 to 500 ㎛.
또한, 나노와이어(30)는 화학기상증착법에 의하여, 촉매부(20)에 부착될 수 있다.In addition, the nanowires 30 may be attached to the catalyst unit 20 by chemical vapor deposition.
공기가 필터를 통과할 때, 입자는 몇 가지 메커니즘을 통해 유선(streamline)을 벗어나 필터 표면과 충돌하여 포집된다. 미세입자의 주요 포집 메커니즘은 확산(diffusion), 차단(interception), 관성충돌(inertial impaction), 중력침강(gravitational settling), 그리고 정전기력(electrical forces) 등이다.As air passes through the filter, the particles are trapped by colliding with the filter surface out of the streamline through several mechanisms. The major capture mechanisms of microparticles are diffusion, interception, inertial impaction, gravitational settling, and electrical forces.
본 출원에서, 미세입자 필터링하는 방법은 흘러가는 공기 내에 포함된 먼지 등의 입자에 인위적으로 외력을 가해주거나, 공기의 흐름 가운데에 장애물(obstacle) 즉, 나노와이어를 위치함으로써 결과적으로 공기 중에 포함되어 있는 미세입자를 분리해낼 수 있다.In the present application, the method for filtering fine particles is included in the air by artificially applying external force to particles such as dust contained in flowing air, or by placing an obstacle, ie, nanowire, in the middle of the air flow. The fine particles present can be separated.
기체 속에 부유하고 있는 미세입자들은 브라운 운동을 하게 되는데, 유동이 물체 주위를 흘러갈 때, 브라운 운동에 의해 유선을 벗어나 물체 에 도달하게 되는 입자는 물체에 부착되게 된다. 브라운 운동은 작은 크기의 입자일수록 더 활발하게 일어나므로, 이 원리는 초미세 먼지를 제거하는 가장 중요하게 작용하는 메커니즘일 수 있다.The fine particles suspended in the gas undergo Brownian motion. When the flow flows around the object, the particles that reach the object through the Brownian motion and reach the object are attached to the object. Since Brownian motion is more active with smaller particles, this principle may be the most important mechanism for removing ultra-fine dust.
비록 미세먼지의 궤도가 유선(streamline)으로부터 벗어나지 아니할지라도, 만약에 유선이 나노와이어 표면으로부터 입자의 반경보다 내부에 있을 때에는 입자가 여전히 포집된다. 실제의 유한한 크기를 가지는 입자는 브라운운동을 하지 않더라도 차단(interception) 효과에 의해서 포집 될 수 있다.Although the trajectory of the fine dust does not deviate from the streamline, the particle is still collected if the streamline is inside the radius of the particle from the nanowire surface. Real finite particles can be captured by the interception effect even without Brownian motion.
또한, 미세먼지의 유선은 나노와이어 근처에서 곡선을 이룬다. 유한한 질량을 가지고 흐름에 따라 이동하는 입자는 그들이 지니는 관성때문에 유선이 곡선인 경우 유선을 정확하게 쫓아가지 못한다. 만약 유선의 곡률이 심하고 입자의 질량이 크다면, 입자는 유선으로부터 매체의 표면으로 이탈하여 충돌하게 되며, 이를 통하여 미세 먼지를 포집 할 수 있다.In addition, the fine dust streamline curves near the nanowires. Particles that move with flow with finite mass do not correctly follow the mammary gland when the mammary gland is curved because of their inertia. If the curvature of the streamline is severe and the mass of the particle is large, the particles will collide and escape from the streamline to the surface of the medium, thereby collecting fine dust.
이러한 다양한 원리에 의하여, 다양한 크기의 먼지를 용이하게 포집할 수 있다.By these various principles, it is possible to easily collect dust of various sizes.
