All solid electrochromic windows were assembled by using an anodically coloring poly(aniline N-butylsulfonate) ion conducting polymer electrolyte, and a cathodically coloring tungsten trioxide. Ion conducting polymers were prepared via photo cross-linking reactions of poly(ethylene glycol)-modified methacrylates with tri(propylene glycol) diacrylate in the presence of a photo initiator and LiClO4. Cyclic life and the color contrast of the all solid state window were enhanced by the introduction of styrene and butylmethacrylate, and H+-conducting Nafion into the electrolyte. Lifetime tests show that the electrochromic window could support more than 2 × 103 cycles, of 60 sec duration.
