Abstract

전기도전입자는 전기크롬물질로 도포되는 전기도전성의 비금속입자를 구비한다. 그러한 전기도전입자는 전기적으로는 도전성이나 필수적으로 이온적으로 절연성의 복합층을 마련하는데 유용한 중합체 현탄액내에 제공될 수 있다.
복합층(3a)는 이온도전층(4)이 전기크롬물질과 접촉하고 있는 전기크롬 표시장치용의 적층에서 사용될 수 있다. 이온도전층과 전기크롬물질의 계면에 전압을 인가함으로써 전기크로효과가 발생된다. 바람직한 전기도전입자는 안티모니도프 주석산화물의 층과 폴리아닐린 또는 폴리피롤과 같은 전기크롬물질의 층으로 도포되는 이산화티탄늄 입자를 구비하고 있다. 바람직한 현탄액과 적층에서 전기도입자는 광투과성 중합체 매트릭내에 분산되어 있다.
본 발명의 물질은, 예를 들어 프린트 방법에 의해 가요성 표시장치를 매우 빠른 속도로 제조할 수 있게 하여 준다.
