Abstract

A new all-solid-state electrochromic device (SED) employing prussian blue and WO3 particulate film with poly (vinyl chloride) (PVC) gel electrolyte has been fabricated. A reversible color change between blue and colorless was observed when an appropriate potential was applied repeatedly to the SED. When the potential cycled more than 1000 times, less than 2% of the electrochromic characteristics were lost.
