Abstract

CuNWs(Copper nanowires) are attracting attention as a transparent electrode material because of their excellent electrical conductivity, high mechanical flexibility, and cost-effectiveness. However, since copper nanowires are easily oxidized, there is a disadvantage that properties of the transparent electrode may be deteriorated due to this, and researches are being conducted to improve this. Accordingly, in this review, various methods and studies to prevent oxidation and improve stability of copper nanowire transparent electrodes by using coating materials such as carbon-based materials, metals, and conductive polymers are introduced. Through this, we intend to provide solutions to solve the problem of development and oxidation of copper nanowire-based technology.

구리 나노와이어(CuNW)는 전기 전도도가 우수할 뿐만 아니라 높은 기계적 유연성과 비용 효율성 등의 장점이 있다. 그러나 구리 나노와이어는 산화가 쉽게 일어나기 때문에 투명 전극의 특성까지도 저하될 수 있다는 단점 또한 존재한다. 따라서, 이러한 문제점을 해결하기 위한 연구들이 진행되고 있다. 이에 본 고에서는 탄소 기반 물질, 금속, 전도성 고분자 등의 코팅용 소재를 활용하여 구리 나노와이어 투명전극의 산화를 방지하고 안정성을 향상시키기 위한 다양한 방법과 연구를 소개한다. 이를 통해 구리 나노와이어 기반 기술의 발전과 산화에 대한 문제를 해결할 수 있는 방안들을 제공하고자 한다.
