摘要
取 W粉、H2 O2 和无水乙醇混合于烧杯中 ,电磁搅拌 3 h,得淡黄色 WO3浊液 ,室温下将饱和溶液恒电流( 3 m A / cm2 )电解一定时间 ,于导电玻璃上电沉积 WO3薄膜 ,发现此水化薄膜的变色行为反常 ,无须正负通电变色 .在通负电变色后 ,只要断电 ,立即自动恢复无色状态。
Selecting proper electrical density, WO 3 thin film was electrodeposited on conducting glass using particular method. The results showed that the electrochromic behavior of WO 3 thin film was anomalous. after electrochromic under negative electricity, If electricity was cut off, the WO 3 thin film recovered transparent in no time, and thus have wide prospect.
