Abstract: A novel kind of polymeric solid electrolyte, PVSEO21, possessing both ion conductivity and electrochromism, was synthesized. PVSEO21-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.

Key words: polymeric solid electrolyte, ion conductivity, electrochromism, polyether, bipyridine
