Abstract
Polymeric coating materials used to protect electrochromic devices from environmental and mechanical damage are provided. The protective polymeric coating materials are physically, chemically and optically compatible with the electrochromic cell layers of electrochromic devices. The polymeric coating materials are polymers having generic polymer back-bones selected from the group of polyimides, polybenzimidazoles, polybenzothiazoles, polybenzoxazoles, poly(phenylene ethers), polyquinolines, polycarbonates, and polysulfones.
