摘要
合成了兼具离子电导性和电致变色性能的聚合物固体电解质(PVSEO_(21))。以其为基材的固态ECD具有双面显示功能,驱动电压>1.5V,着色和消色响应时间0.6和1.1秒(+2.0～—2.0V),开路记忆半衰期约5小时,着色后的最大吸收波长549nm,能可逆地显示蓝紫色和淡黄色。
A novel kind of polymeric solid electrolyte, PVSEO_(21), possessing both ion conductivity and electrochromism, was synthesized. PVSEO_(21)-based solid ECD was characterized by double-side displaying property. The driving voltage was greater than 1.5V. Response time for coloring and bleaching was 0.6s and 1. 1s, respectively. The half memory life under open circuit was about 5 hours. The maximum absorption wavelength of its coloring state located at 549 nm,and it could display the color from bluish violet to pale yellow reversibly.
