| 摘 要： | 用现场椭圆偏振技术在330-700nm波长范围内研究了从酸性水溶液中电聚合而成的聚苯胺膜的电变色反应。膜的还原态(-0.2V)在390-400nm、氧化态(0.55V)在500-530nm出现椭圆谱峰;从还原态(黄色)到氧化态(绿色)的电变色反应要经历一个中间态,其谱峰出现在466-470nm。

| Abstract: | The electrochromism of polyaniline films, which is prepared by electropolymer-ization from aniline in acidic aqueous solution onto platinum,is investigated in 330-700nm through in-situ ellipsometric technique. The results indicate that the ellipsometric peak of the reduced state(-0. 2V) of the film appears at 390-400nm and the oxidized state(0. 55V) at 500-530nm. The elec-trochromic reaction from the reduced "yellow" state to the oxidized "green" state is suggested via intermediate state whose ellipsometric peak appears at 466-470nm. |
