초록
정보.통신 분야의 발전에 따라 기존의 전자 기기들은 평면성을 벗어나 투명.유연하고 깨지지 않는 특성이 요구되고 있다. 이러한 부가적인 특성을 갖춘 기기들의 제조를 위해서는 전극의 투명성과 유연성을 동시에 갖고 있어야 하지만, 현재 가장 대표적으로 이용되는 투명전극인 ITO (Indium Tin Oxide)는 유연하지 못하다는 단점과 자원적인 한계를 갖고 있다. 이에 따라 ITO의 한계를 극복하기 위해 다양한 물질들을 이용한 대체 재료 개발이 활발히 연구되고 있으며 대체 물질들의 복합화를 통해 더 향상된 물성을 발현시키기 위한 연구가 진행되고 있다. 본 총설에서는 ITO의 한계를 극복하고 투명전극으로서의 응용 가능한 대체 물질들에 대한 연구 현황을 정리하였다.
Flexibility of a transparent device has been required in accordance with miniaturization and mobilization needs in recent industry. The most representative material used as a transparent electrode is indium tin oxide (ITO). However, a couple of disadvantages of ITO are the exhaustion of natural resource of indium and its inflexibility due to inorganic substance. To overcome the limit of ITO, a variety of alternative materials have been researched on development of transparent electrodes and its properties through composite materials. In this review, we classify some of emerged materials with their general studies.
