Photovoltaic Properties of Polyaniline Film

聚苯胺膜的光电流响应辜志俊，陈衍珍（化学系固体表面物理化学国家重点实验室）聚苯胺是重要导电聚合物。近年来，国内外对聚苯胺的电聚合、导电机理、结构特性和氧化还原性能等进行广泛的研究，对聚苯胺的光电流响应的研究也有所报道￣［１～３］。本文研究酸性溶液中，...

polyaniline film can produce photocurrent in acid solution under illumi-nation with visible light.At different potential,polyaniline film electrode induces reversiblechange of photoanodic and photocathodic current.This speciality involves transformation ofPand n type semiconductor structure of polyaniline film. Fe (CN)I￣(1-) and Cu￣(2+) ionscan dope into polyaniline film and participate in the photovoltaic effect.The speciality,re-sponse time,intensity and transitional potential of photocurrent change greatly.
