Description
본 발명은 2층 구조의 하이브리드 투명 전극 및 그 제조 방법에 관한 것으로, 구체적으로는 프린팅 공정을 사용하여 투명 전극을 나노 입자층 및 나노선 층의 2개 층으로 구성된 하이브리드 구조를 갖는 투명 전극 제조 방법에 관한 것이다.
The present invention relates to a hybrid transparent electrode having a two-layer structure and a method of manufacturing the same, and specifically, to a transparent electrode manufacturing method having a hybrid structure composed of two layers of a nanoparticle layer and a nanowire layer by using a printing process. It is about.
이동성이 강조되는 유비쿼터스 정보화 시대에 진입하면서 평판 디스플레이의 핵심소재인 투명전극 관련 산업의 중요성이 부각되고 있다. As the ubiquitous informatization era, which emphasizes mobility, the importance of the transparent electrode-related industry, which is a key material for flat panel displays, has emerged.
투명전극은 지금까지 대전방지막, 열반사막, 면발열체, 광전변환소자 및 각종 평판디스플레이에 사용되어 왔고, 최근에는 LCD 및 평판디스플레이의 수요가 TV 등 대형기기와 휴대전화, 전자수첩 등의 휴대용 소형기기를 중심으로 확대되면서 공급물량이 급속히 증가하고 있는 추세다.Transparent electrodes have been used in antistatic films, heat reflecting films, surface heating elements, photoelectric conversion elements and various flat panel displays. In recent years, the demand for LCDs and flat panel displays has been largely demanded for large devices such as TVs and portable small devices such as mobile phones and electronic notebooks. As supply centers expand, supply is increasing rapidly.
ITO를 투명 전극으로 사용하기 위해서는 무색/고투과도/고전도도가 필수적으로 요구된다는 문제가 있지만, 현재까지 ITO에 버금가는 물리적/전기적 특성을 갖춘 물질은 개발되지 못하고 있는 실정이나, 대표적인 희금속인 인듐 사용량을 감소시키기 위한 연구가 진행중이다.
In order to use ITO as a transparent electrode, there is a problem that colorless / high transmittance / high conductivity is indispensable.However, materials with physical and electrical properties comparable to those of ITO have not been developed until now, but the amount of indium, which is a representative rare metal, is used. Research is underway to reduce this risk.
일반적으로 투명전극을 구성하는 방법 중 하나인 ITO 기상 증착 후 포토리소그래피(Photolithography)/에칭(Etching) 공정은 스퍼터링 공정에서 다량의 인듐을 소모하는 대표적인 공정으로, 챔버 내벽에 인듐이 필요없이 코팅되어 낭비되고, 스퍼터링시 타겟 사용율이 30% 정도에 불과하고 이를 재활용함에 따라 효율이 저하되며, 오염물이 발생한다는 단점을 갖는다.
In general, the photolithography / etching process after ITO vapor deposition, which is a method of forming a transparent electrode, is a representative process that consumes a large amount of indium in a sputtering process. In addition, the target use rate of sputtering is only about 30%, and the efficiency is reduced by recycling it, and has the disadvantage of generating contaminants.
투명전극을 구성하는 또 다른 방법인 잉크젯 프린팅(Inkjet printing)은 나노급 ITO 분말 또는 졸(sol)/겔(gel) 형태로 존재하는 ITO 잉크/페이스트를 제조하여 이를 직접 패턴의 형상으로 기판에 도포하는 기술로써, 포토리소그래피 및 에칭 공정 없이 직접 패턴을 형성하므로 공정이 간단해지고 비용이 적게 들어가며, 에칭되어 소모되는 ITO의 양을 줄일 수 있다는 장점을 가지나, 투명 전극이 ITO 입자만으로 구성되기 때문에 전기 저항을 낮추는데 한계가 있다. 또한, 잉크/페이스트의 직접 패터닝 이후 약 300~500의 불활성/환원 분위기에서 후열처리 공정이 필요하기 때문에, 기판의 열적 손상을 피할 수 없게 된다.
Inkjet printing, another method of constructing a transparent electrode, prepares ITO ink / paste in the form of nano-grade ITO powder or sol / gel and directly applies it to the substrate in the form of a pattern. As a technology to directly form a pattern without photolithography and etching process, the process is simpler, less expensive, and the amount of ITO consumed by etching is reduced, but since the transparent electrode is composed of only ITO particles, electrical resistance There is a limit to lowering. In addition, since the post-heating process is required in an inert / reducing atmosphere of about 300 to 500 after the direct patterning of the ink / paste, thermal damage of the substrate cannot be avoided.
이러한 문제를 해결하기 위해 안출된 방법이, 기판상에 금속선을 코팅하여 금속선층을 형성한 후 금속선 층 내에 금속 입자를 함침함으로써 도1에 도시된 바와 같이, 금속선 층 내에 금속 입자를 혼합하는 방법으로, 이는 이종 물질이 한 층 내에 섞여 있어 금속 입자 분포의 균일성이 저하될 수 있고, 금속 입자의 이동 등으로 인해 투명전극의 장기적인 신뢰성이 저하되는 문제점이 있다.
The method devised to solve this problem is to coat the metal wire on the substrate to form a metal wire layer, and then impregnate the metal particles in the metal wire layer, as shown in FIG. 1, to mix the metal particles in the metal wire layer. This is because heterogeneous materials are mixed in one layer, thereby decreasing the uniformity of distribution of metal particles, and deteriorating long-term reliability of the transparent electrode due to movement of metal particles.
