Description
본 발명은 흡방습능이 우수하고 부착강도가 우수한 건축마감용 수용성 도료 조성물 및 이를 이용한 도장방법에 관한 것이다.The present invention relates to a water-soluble paint composition for architectural finishing having excellent moisture absorptive and desorptive ability and excellent adhesion strength, and a painting method using the same.
건축마감재란 시멘트 콘크리트, 뿐만 아니라 목재, MDF, 석고보드 등으로 이루어진 건축물의 내벽, 바닥면, 외벽의 표면에 부착되어 외관적 미려함이나 단열, 방수 등의 기능을 수행하기 위하여 사용되는 통상의 건축 내외장 자재를 말한다. 시멘트 콘크리트에서는 암모니아 등 유독성 가스가 방출되기도 하며, 건축마감재 접착하기 위한 접착제는 용매 대부분이 두통과 호흡기 질환 등 건강에 해를 미치는 포름알데히드와 톨루엔, 자일렌 등의 휘발성 유기화합물(VOC)을 포함하고 있다.A building finishing material is a typical building material that is attached to the surface of the inner wall, floor, or outer wall of a building made of cement concrete, wood, MDF, gypsum board, etc. refers to exterior materials. Toxic gases such as ammonia are released from cement concrete, and most of the solvents used in adhesives for bonding building finishing materials contain formaldehyde, toluene, and volatile organic compounds (VOC) that are harmful to health, such as toluene and xylene. there is.
이에 따라 최근 주거공간 건축물의 마감용 재료로 친환경 소재에 대한 관심이 어느 때보다 높아져 건축마감용 재료로 바이오 세라믹, 천연 광물 등을 혼합한 친환경 무기재료를 사용하고 있으나, 무기물을 다량 혼합함으로 인해 도료의 장시간 보관시 침전이 발생하기 쉽고 도장시 작업성이 떨어지는 문제가 있었다.As a result, interest in eco-friendly materials has increased more than ever as a finishing material for residential buildings, and eco-friendly inorganic materials mixed with bioceramics and natural minerals are used as building finishing materials. When stored for a long time, precipitation is easy to occur, and workability is poor during painting.
또한, 핵심 무기물인 흡방습 재료를 과다 투입함으로 인해 도막의 강도가 약하고, 부착성과 부착강도가 떨어지며, 도막의 건조 후에도 무기물이 손에 묻어나는 문제가 있었다. 따라서 도료 조성물 내 무기물의 함량을 낮추면서도 흡방습, 항균, 탈취 등 물성을 유지하며 부착강도가 우수한 건축마감 도장용 도료 조성물의 개선이 필요한 실정이다.In addition, due to excessive input of a moisture absorption and desorption material, which is a key inorganic material, the strength of the coating film is weak, adhesion and adhesion strength are reduced, and inorganic materials remain on the hand even after the coating film is dried. Therefore, there is a need to improve a paint composition for architectural finishing painting having excellent adhesion strength while maintaining physical properties such as moisture absorption and desorption, antibacterial, and deodorization while lowering the content of inorganic substances in the paint composition.
본 발명에서는 항균, 탈취 및 흡방습 효과가 우수한 다공성 금속유기구조체(Metal Organic Framework, MOF)를 무기 분말의 주 성분으로 첨가함으로써, 전체 무기물의 첨가량을 줄여 도막의 강도와 부착강도를 높이고 도막의 건조 후에도 무기 분말이 묻어나지 않는 수용성 도료 조성물을 제공하고자 한다.In the present invention, by adding a porous metal organic framework (MOF), which has excellent antibacterial, deodorizing, and moisture absorption and desorption effects, as the main component of the inorganic powder, the total amount of inorganic substances added is reduced to increase the strength and adhesion strength of the coating film and dry the coating film. It is an object of the present invention to provide a water-soluble coating composition in which inorganic powder does not remain even after use.

Specifically, the acrylic compound is methyl methacrylate (MMA), dimethylaminoethyl methacrylate (DMAEMA), diethylaminoethyl methacrylate (DEAEMA), normal isopropyl acrylamide (NIPAM), acrylomolepine ( ACMO), N,N-dimethylacrylamide (DMAA), N,N-diethylacrylamide (DEAA), acrylamide (AAM), N-butoxymethylacrylamide (N-BMAA), I-butoxymethyl Acrylamide (I-BMAA), N-hydroxyethylacrylamide (N-HEAA), N-methylolmethacrylamide (N-MMAA), butyl acrylate (BAM), acrylic acid, methacrylic acid, methyl acrylate , ethyl acrylate, propyl acrylate, isopropyl acrylate, n-butyl acrylate, isobutyl acrylate, n-amyl acrylate, isoamyl acrylate, n-hexyl acrylate, ethylhexyl acrylate, 2-hydroxy Roxymethyl acrylate, hydroxyethyl acrylate, hydroxypropyl acrylate, lauryl acrylate, propyl methacrylate, isopropyl methacrylate, n-butyl methacrylate, isobutyl methacrylate, n-amyl methacrylate acrylate, isoamyl methacrylate, n-hexyl methacrylate, 2-ethylhexyl methacrylate, hydroxyethyl methacrylate, hydroxypropyl methacrylate, lauryl methacrylate, and mixtures thereof can be selected from the group.
또한, 본 발명의 아크릴 화합물은 반복단위에 아민기를 포함할 수 있으며, 중합되는 아크릴 화합물 중 아민기를 갖는 비율이 10% 이상인 것이 바람직하며, 상한은 60% 이하일 수 있다. 아민기가 도입된 아크릴 화합물을 필수적으로 반복단위로 포함함에 따라, 본 발명의 도료 조성물은 도장 후의 외관, 내스크래치성, 경도, 내약품성을 향상시킬 수 있다. In addition, the acrylic compound of the present invention may include an amine group in a repeating unit, and the ratio of having an amine group in the polymerized acrylic compound is preferably 10% or more, and the upper limit may be 60% or less. As the acrylic compound into which an amine group is introduced is essentially included as a repeating unit, the paint composition of the present invention can improve appearance after painting, scratch resistance, hardness, and chemical resistance.
아민기는 이온화하여 수분산성을 높일 수 있으며, 후술할 바인더 수지의 일 구성요소인 산을 통해 암모늄 등의 양이온 형성 후 수분산을 통해 수용성 아크릴 수지를 형성할 수 있다. 또한, 아민기는 유기물과 무기물 사이의 반응을 유도하고 화학적 결합을 형성하여 도막의 결합강도를 증가시키며, 이를 통해 부착강도와 도막강도를 향상시킬 수 있다. The amine group may be ionized to increase water dispersibility, and a water-soluble acrylic resin may be formed through water dispersion after formation of cations such as ammonium through an acid, which is a component of a binder resin to be described later. In addition, the amine group induces a reaction between the organic material and the inorganic material and forms a chemical bond to increase the bonding strength of the coating film, thereby improving the adhesion strength and the coating film strength.
상기 아크릴 화합물은 해리된 카제인에 의해 상호 연결됨으로써 복합체 간의 가교 및/또는 결합성이 개선될 수 있다. 그 결과 목재, 시멘트 콘크리트 뿐만 아니라 철재와 같이 상대적으로 수성 도료의 부착성이 미흡한 소재에도 강한 접착성을 나타낼 수 있다.The acrylic compounds may be interconnected by the dissociated casein, thereby improving cross-linking and/or binding properties between the complexes. As a result, it can show strong adhesion not only to wood and cement concrete, but also to materials that have relatively poor adhesion to water-based paints, such as steel.
상기 아크릴계 고분자 화합물은 pH가 조절되어 해리된 카제인의 존재 하에서 아크릴 단량체를 중합시켜 형성될 수 있다. 열중합개시제는 본 발명이 속하는 기술분야에서 공지된 개시제라면 제한 없이 사용할 수 있다. 예를 들어, 과산화황산암모늄, 과산화황산칼륨과 같은 공지의 유기과산화물 개시제를 이용하여 중합을 개시할 수 있으며, 구체적으로 벤조일 퍼옥시드, 디부틸 퍼옥시드, t-부틸퍼옥시벤조에이트, t-부틸퍼옥시(2-에틸헥사노에이트), AIBN(아조비스이소부티로니트릴) 또는 이들의 혼합물을 사용할 수 있다. 또한 상기 아크릴 단량체를 검화시킨 후 중합을 개시하면 카제인과의 혼합성이 개선되어 복합체의 형성이 보다 용이할 수 있다.The acrylic polymer compound may be formed by polymerizing acrylic monomers in the presence of casein dissociated by adjusting the pH. As the thermal polymerization initiator, any initiator known in the art to which the present invention pertains may be used without limitation. For example, polymerization may be initiated using a known organic peroxide initiator such as ammonium peroxide sulfate or potassium peroxide sulfate. Specifically, benzoyl peroxide, dibutyl peroxide, t-butylperoxybenzoate, t-butyl Peroxy(2-ethylhexanoate), AIBN (azobisisobutyronitrile) or mixtures thereof may be used. In addition, when the polymerization is initiated after saponification of the acrylic monomer, the mixing property with casein is improved, and thus the formation of the complex may be facilitated.
카제인이 결합된 아크릴계 고분자 화합물 복합체는 카제인 농도가 1 내지 5 중량%일 수 있다. 카제인 농도가 상기 범위를 벗어나면 충분한 접착성을 부여할 수 없거나, 조성물이 겔화되어 도료로 적용하기 어려울 수 있다.The casein-bound acrylic polymer compound complex may have a casein concentration of 1 to 5% by weight. If the casein concentration is out of the above range, sufficient adhesiveness may not be imparted, or the composition may be gelated, making it difficult to apply it as a paint.
상기 복합체는 pH가 4 내지 5일 수 있다. 상기 조성물의 pH가 상기 범위를 벗어나면 복합체 조성물이 형성되지 않을 수 있다. 보다 구체적으로, 카제인은 pH 3.5 내지 5.5의 범위에서 용해도가 낮은 특성을 나타내는데 이러한 조건 하에서 아크릴 단량체를 중합시켜야 아크릴계 중합체 고분자 간에 해리된 카제인이 결합된 복합체를 제조할 수 있다. 상기 범위를 벗어나는 조건에서 중합을 수행하면 카제인이 용액화되어 아크릴계 고분자와 카제인의 상호작용이 발생하지 않을 수 있다.The complex may have a pH of 4 to 5. If the pH of the composition is out of the above range, a complex composition may not be formed. More specifically, casein exhibits low solubility in the range of pH 3.5 to 5.5, and acrylic monomers must be polymerized under such conditions to prepare a complex in which casein dissociated between acrylic polymers is bound. When polymerization is performed under conditions outside the above range, casein is liquefied, and interaction between the acrylic polymer and casein may not occur.
상기 복합체는 25℃점도가 300 내지 1,000cps일 수 있다. 점도가 상기 범위를 벗어나면 도료가 건조되기 전에 쉽게 흐르거나, 도료의 도포가 어려울 수 있다.The composite may have a viscosity of 300 to 1,000 cps at 25 °C. If the viscosity is out of the above range, the paint may flow easily before drying, or it may be difficult to apply the paint.
본 발명의 바인더 수지는 산을 포함하며, 이는 바인더 수지의 수용성을 제고하기 위함이다. 산은 1가 산이 바람직하며, 구체적으로는 초산, 질산, 염산, 및 이들의 혼합물로 이루어진 군으로부터 선택될 수 있고, 바람직하게는 초산일 수 있다. 상기 산은 상술한 아민기를 이온화하여 수분산시키는 역할을 할 수 있으며, 그 함량이 상기 범위를 초과할 경우 경화 반응 속도가 느려지고, 반면에 상기 범위 미만일 경우 액상이 불투명해지는 문제가 발생할 수 있다.The binder resin of the present invention contains an acid, which is to improve the water solubility of the binder resin. The acid is preferably a monovalent acid, and specifically, may be selected from the group consisting of acetic acid, nitric acid, hydrochloric acid, and mixtures thereof, preferably acetic acid. The acid may play a role of ionizing and dispersing the above-described amine group, and when the content exceeds the above range, the curing reaction rate slows down, whereas when the content is below the above range, the liquid phase may become opaque.
바인더 수지의 무기용제는 물, 알코올, 케톤 등을 포함할 수 있고, 친환경성 및 작업성의 측면에서 물을 사용하는 것이 바람직하다. 본 발명에서는 유기용제 대신 물을 사용함으로써 인체에 해로운 휘발성 유기화합물(VOCs)을 배제할 수 있어 친환경적이며, 유기물 혼합 시 급격한 발열반응을 제어할 수 있는 장점이 있다.The inorganic solvent of the binder resin may include water, alcohol, ketone, etc., and it is preferable to use water in terms of environmental friendliness and workability. In the present invention, by using water instead of an organic solvent, it is environmentally friendly because it can exclude volatile organic compounds (VOCs) harmful to the human body, and has the advantage of being able to control a rapid exothermic reaction when organic substances are mixed.
또한, 본 발명의 바인더 수지 무기용제로 물을 사용할 경우, 상기 물은 복령 및 후박나무 천연추출물을 포함할 수 있다. 천연추출물은 물과 0.1:1 내지 0.4:1의 중량비로 혼합되어 바인더 수지에 사용될 수 있다. 물 중량 대비 0.1 미만일 경우에는 천연추출물의 효과가 미미하며, 0.4 초과의 경우에는 도료 조성물의 분산성과 점도의 문제가 나타날 수 있다. 본 발명에서는 복령 및 후박나무 천연추출물을 첨가함으로써 항균, 항염증, 항산화 등의 작용를 통해 피부에 직접적으로 닿을 수 있는 도막에 하기 효과들을 부여하고자 한다. In addition, when water is used as the inorganic solvent for the binder resin of the present invention, the water may include natural extracts of Bokryeong and Zucchini tree. The natural extract may be mixed with water in a weight ratio of 0.1:1 to 0.4:1 and used for the binder resin.

도료 조성물의 무기 분말은 바인더 수지 전체 중량 대비 제올라이트 10 내지 20 중량부, 규조토 10 내지 30 중량부 및 다공성 금속유기구조체(MOF) 20 내지 50 중량부를 포함할 수 있다.The inorganic powder of the coating composition may include 10 to 20 parts by weight of zeolite, 10 to 30 parts by weight of diatomaceous earth, and 20 to 50 parts by weight of a porous metal organic structure (MOF) based on the total weight of the binder resin.
제올라이트는 공극구조와 고유의 물성 및 기능성의 특성을 이용하여 복합적 기능을 구비하는 수단으로 이용되는데, 상세히 살펴보면 넓은 표면적을 가지는 3차원 세공(Pore)구조를 통기성의 흡음구조 형성에도 적합하게 적용하여 우수한 방음 효과를 기대하는 수단과, 촉매제 및 이온교환 기능, 항 박테리아 기능을 적용하는 수단과, 3차원 세공(Pore)구조를 이용한 도막의 조습 작용으로 이용하는 수단과, 암모니아 등 생활냄새를 흡착 탈취하는 수단으로 사용될 수 있다.Zeolite is used as a means to have multiple functions by using the pore structure and its unique physical properties and functional properties. Looking in detail, a 3-dimensional pore structure with a large surface area is suitably applied to the formation of a breathable sound-absorbing structure, resulting in excellent A means for expecting a soundproofing effect, a means for applying a catalyst, an ion exchange function, and an antibacterial function, a means for using a 3-dimensional pore structure to control the humidity of a coating film, and a means for adsorbing and deodorizing life odors such as ammonia. can be used as
상기 제올라이트는 결정격자 구조 내에 규소(Si), 알루미늄(Al), 은(Ag) 원자를 함유하는 물질뿐 아니라, 규소, 알루미늄, 은에 대한 치환 원소를 함유하는 물질을 포함한 것일 수 있다. 즉, 제올라이트는 표면에 은(Ag) 이온 성분이 치환되어 포함되거나 비결정질의 실리카알루미나-제올라이트 복합체일 수 있다. 이러한 금속성 제올라이트의 입경은 1 내지 5 ㎛ 범위일 수 있다.The zeolite may include a material containing silicon (Si), aluminum (Al), and silver (Ag) atoms in a crystal lattice structure, as well as a material containing substitution elements for silicon, aluminum, and silver. That is, the zeolite may include a silver (Ag) ion component substituted on the surface or may be an amorphous silica alumina-zeolite composite. The particle diameter of this metallic zeolite may range from 1 to 5 μm.
이러한 제올라이트는 하기의 두가지 방법으로 항균 또는 항바이러스 효과를 구현할 수 있다. 첫번째 방법으로, 제올라이트 부근에 세포성 물질인 세균이나 곰팡이 등이 위치하면, 금속이온 성분이 쉽게 해리되어 분산에 의해 세균과 곰팡이의 세포막에 도달하고, 이 세포막의 단백질에 흡착됨과 동시에 세포의 구조 파괴를 일으켜 세균과 곰팡이 등의 에너지대사를 불능으로 만들어 균 자체를 사멸시킨다. 두번째 방법으로, 활성산소(Active oxygen)에 의한 살균 작용이 있다. 구체적으로, 세라믹 무기질 소재인 제올라이트를 담체로 하여 제조되고 SiO2, Al2O3 등의 금속 산화물로 구성되어 있기 때문에, 골격 구조에 결합되어 있는 산소들이 부분적으로 활성산소로 전환된다. 이 활성산소는 항균 금속과 마찬가지로 세균이나 곰팡이의 세포막 등의 단백질 층에 흡착되어 강력한 살균효과를 나타낸다.These zeolites can implement antibacterial or antiviral effects in the following two ways. In the first method, when bacteria or fungi, which are cellular materials, are located near zeolite, metal ion components are easily dissociated and reach the cell membranes of bacteria and fungi by dispersion, and are adsorbed to proteins of the cell membranes and destroy the cell structure at the same time. causes the energy metabolism of bacteria and fungi to become inoperable and kills the bacteria themselves. As a second method, there is a sterilization action by active oxygen. Specifically, since it is manufactured using zeolite, which is a ceramic inorganic material, as a carrier and is composed of metal oxides such as SiO 2 and Al 2 O 3 , oxygen bound to the skeleton structure is partially converted into active oxygen. Like the antibacterial metal, this active oxygen is adsorbed on the protein layer of the cell membrane of bacteria or fungi and exhibits a strong sterilization effect.
제올라이트 내에 치환되어 포함되는 실리카 및/또는 알루미나 외에, 무기 분말은 개별적으로 실리카 또는 알루미나 분말을 각각 1 내지 10 중량부 더 포함할 수 있다.In addition to the silica and/or alumina substituted and included in the zeolite, the inorganic powder may further include 1 to 10 parts by weight of silica or alumina powder individually.
실리카(SiO2)는 도막의 난연성을 증가시키기 위한 소광제로 그 자체로서 첨가될 수 있으며, 이때 실리카 나노세라믹 입자의 평균 입경은 500 내지 2000 nm 범위인 것이 바람직하다. 또는 1 내지 5 nm의 은나노 입자를 결합한 은나노-실리카 복합체(Silver-Silica Composite)로 첨가될 수도 있다. 은나노-실리카 복합체는 빛이 없는 조건에서도 촉매 기능을 발휘하여 항균 및 탈취 기능을 가지며, 빛이나 열에너지를 흡수할 경우 촉매 효과가 더욱 증대될 수 있다. Silica (SiO 2 ) may be added as a matting agent for increasing the flame retardancy of the coating film, and in this case, the average particle diameter of the silica nanoceramic particles is preferably in the range of 500 to 2000 nm. Alternatively, it may be added as a silver nano-silica composite in which silver nanoparticles of 1 to 5 nm are combined. The silver nano-silica composite exhibits a catalytic function even in the absence of light and has antibacterial and deodorizing functions, and the catalytic effect can be further increased when light or thermal energy is absorbed.
알루미나(Al2O3)는 높은 경도를 가지며 강도 및 내식성이 뛰어나다. 또한 높은 열적 안정성으로 인해 피착물의 온도 상승을 방지하여 수축, 팽창을 감소시키며 중성화/염화를 방지하여 도장의 내구성을 장기간 유지시킬 수 있다. 이러한 효과는 알루미나 나노세라믹 입자의 평균입경을 500 내지 1500 nm 범위로 첨가할 때 나타나며, 초미립자 분말이 건조 중에 도막의 표면으로 부상하여 치밀하고 경도가 높은 도막을 형성할 수 있다.Alumina (Al 2 O 3 ) has high hardness and excellent strength and corrosion resistance. In addition, due to its high thermal stability, it is possible to maintain the durability of the paint for a long period of time by preventing the temperature rise of the adherend, reducing shrinkage and expansion, and preventing neutralization/chlorination. This effect appears when the average particle diameter of alumina nanoceramic particles is added in the range of 500 to 1500 nm, and ultrafine particle powder floats to the surface of the coating film during drying to form a dense and high hardness coating film.
규조토는 도막 표면에 다공성을 부여하고 광택을 조절하며 크랙을 방지하는 역할을 한다. 규조토는 10 내지 30 중량부 포함될 수 있으며, 10 중량부 미만일 경우 도막 표면의 다공성이 불충분하여 항균 및 항바이러스 기능이 열위해질 수 있고, 광택 조절 및 크랙 방지 효과가 불충분할 수 있다. 반면, 30 중량부 초과하는 경우 크랙 방지에 악영향을 줄 수 있다.Diatomaceous earth provides porosity to the surface of the coating film, controls gloss, and prevents cracks. Diatomaceous earth may be included in an amount of 10 to 30 parts by weight, and if less than 10 parts by weight, the porosity of the surface of the coating film may be insufficient, resulting in inferior antibacterial and antiviral functions, and insufficient gloss control and crack prevention effects. On the other hand, if it exceeds 30 parts by weight, crack prevention may be adversely affected.
본 발명에서는 항균, 탈취 및 흡·방습 효과가 우수한 다공성 금속유기구조체(Metal Organic Framework, MOF)를 무기 분말의 주 성분으로 첨가함으로써, 상술한 나머지 무기 분말들의 첨가량을 줄여 도막의 강도와 부착강도를 높이고 도막의 건조 후에도 무기 분말이 묻어나지 않는 것을 특징으로 한다.In the present invention, by adding a porous metal organic framework (MOF), which has excellent antibacterial, deodorizing, and moisture absorption and desorption effects, as a main component of the inorganic powder, the strength and adhesion of the coating film are increased by reducing the addition amount of the remaining inorganic powders described above.

It may be added in a compounding ratio (weight ratio) of 2 to 1:4.

The phosphorus zeolite imidazolate framework (ZIF) has both large and small cavities. As such, the oxide product (Co 3 O 4 ) of ZIF-67 has permanent porosity, and carbon dots (CDs) and copper (Cu) can be deposited as a catalytically active material based on it.
ZIF-67 구조의 코발트 산화물(Co3O4)은 공침법을 이용하여 질산코발트 6수화물(Co(NO3)2·6H2O) 및 Hmim(1-Hexyl-3-methyl-imidazolium)으로부터 얻어지는 ZIF-67 금속유기구조체를 하소하여 다공성 Co3O4을 합성할 수 있다. 구체적으로 상기 공침법은 질산코발트 6수화물 및 Hmim을 각각 메탄올에서 용해시킨 후 혼합 및 교반하고, 상기 혼합용액을 20시간 이상 반응시킨 후 침전물을 원심분리하고 세척 및 건조하여 ZIF-67 금속유기구조체를 얻을 수 있다. 얻어진 ZIF-67 구조의 코발트 산화물(Co3O4)은 12면체이며, 평균 크기가 0.5 내지 2.5 ㎛ 범위일 수 있다.Cobalt oxide (Co 3 O 4 ) of ZIF-67 structure is obtained from cobalt nitrate hexahydrate (Co(NO 3 ) 2 6H 2 O) and Hmim (1-Hexyl-3-methyl-imidazolium) using a co-precipitation method.

(Cu 2+ ) can be incorporated into the ZIF-67 structure. Subsequently, Cu/ZIF-67 may be prepared by heat treatment at 400 to 500° C. to reduce copper ions (Cu 2+ ). At this time, the amount of the Cu nanoparticles combined by deposition may be 5 to 15% by weight, preferably 8 to 12% by weight, considering the yield of the manufacturing method and antibacterial / deodorizing ability.
Cu/ZIF-67는 미세 다공성 구조 내에 항균능을 갖는 구리 원자를 결합시킴으로써, 구리의 첨가로 인한 색상의 변화 등 도막 외관의 변화를 방지하면서도 항균/탈취능을 부여할 수 있다.Cu/ZIF-67 can provide antibacterial/deodorizing properties while preventing changes in the appearance of the coating film, such as color change due to the addition of copper, by binding copper atoms having antibacterial properties in the microporous structure.
CDs/ZIF-67은 상기 제조된 ZIF-67 구조의 코발트 산화물(Co3O4) 12면체를 탄소점(CDs)과 에탄올에서 혼합한 후 초음파 분산 처리하여 증착시키고, 이후 건조를 통해 CDs/ZIF-67를 얻을 수 있다. 여기에서, CDs/ZIF-67에 증착 결합되는 탄소점은 질소 도핑 탄소점(N-doped CDs)일 수 있다. 질소 도핑 탄소점은 키토산(CS)과 아크릴아미드(AAM)를 탄소점의 전구체 역할로 하여 열수 탄화(hydro-thermal carbonization)에 의해 합성할 수 있다. 키토산 및 아크릴아미드의 질량비는 1:15 내지 1:25 범위일 수 있으며, 증착 결합된 탄소점(CDs)의 양은 제조법의 수율을 고려할 때 5 내지 10 중량%일 수 있다.CDs/ZIF-67 was deposited by mixing the cobalt oxide (Co 3 O 4 ) dodecahedron of the above-prepared ZIF-67 structure with carbon dots (CDs) and ethanol, and then ultrasonically dispersing, and then drying the CDs/ZIF.
