All-solid-state electrochromic device of electrodeposited WO3 and prussian blue film with PVC gel electrolyte

Abstract

An all-solid-state electrochromic device (SED) employing electrodeposited WO3 and prussian blue film with poly(vinyl chloride) (PVC) gel electrolyte that has high conductivity (10−3 S/cm) at room temperature has been fabricated. The SED has been found to have excellent electrochromism and memory characteristics. A reversible color change between blue and colorless was observed when an appropriate potential was applied repeatedly to the electrochromic display device. © 1998 John Wiley & Sons, Inc.
