A solid‐state electrochromic device based on polyaniline, prussian blue and an elastomeric electrolyte

Abstract

Advantages of solid‐state electrochemical devices are the ease of production, no possibility of leakage, and no electrolyte evaporation. One result of the search for such a device is the electrochromic display sketched in the Figure, which uses polyaniline and Prussian Blue as the active electrochromic materials and an elastomer containing Li‐ClO 4 as the solid‐state electrolyte. magnified image
