ABSTRACT:
An electrochromic device is provided having an electrochromic conducting polymer layer in contact with a flexible outer layer. A conductive reflective layer is disposed between the electrochromic conducting polymer and a substrate layer. A liquid or solid electrolyte contacts the conductive reflective layer and a counter electrode in the device. A liquid electrolyte may comprise, for example, a mixture of sulfuric acid, poly(vinyl sulfate), and poly(anethosulfonate). A solid electrolyte may comprise, for example, a mixture of sulfuric acid, poly(vinyl sulfate), poly(anethosulfonate), and poly(vinyl alcohol). The electrochromic conducting polymer layer may comprise, for example, poly(diphenyl amine), poly(4-amino biphenyl), poly(aniline), poly(3-alkyl thiophene), poly(phenylene), poly(phenylene vinylene), poly(alkylene vinylenes), poly(amino quinolines), or poly(diphenyl benzidine) and one or more dopants such as poly(styrene sulfonate), poly(anethosulfonate), poly(vinyl sulfate), p-toluene sulfonate, trifluoromethane sulfonate, and poly(vinyl stearate).
