Abstract
Benzyl viologen was synthesized and the electrochromic properties was examined. At an applied voltage of 2.6 V the electrocoloration was appeared but electrooptical response abruptly decreased after a certain period of time. It was a cause that the quality of the ITO film was degraded, e.g. the conductivity of the ITO film reduced from the original value. The ITO surfaces under some different conditions were observed by XRD and SEM.
Benzyl viologen의 전기 변색특성을 조사했다. 인가전압 2.6 V에서는 강한 전기변색 응답성을 나타내지만 반복 내구성이 뛰어나지 못하다. 이러한 현상은 전기 변색소자의 투명 유리전극인 ITO막이 전장하에서 손상을 입기 때문이라는 것을 알 수 있었다. 전압인가 전후의 ITO막의 면저항, XRD, SEM 결과로 부터 ITO막이 마모됨이 입증되었다.
