ELECTROCHROMIC CELL WITH IMPROVED ELECTROLYTE SYSTEM

摘要

27,845 ELECTROCHROMIC CELLS WITH IMPROVED ELECTROLYTE SYSTEM Electrochromic devices are described having a layer of electrochromic material, e.g. WO3, in contact with a layer of organic electrolyte resin, with electrodes for changing electrochromic properties of the device by reversibly applying electric fields across said layers. The electrolyte resin layer comprises a hydrophilic layer of homopolymer of poly(2-acrylamido-2-methyl-propanesulfonic acid) and in some preferred embodiments may further comprise a thinner layer of less hydrophilic electrolyte resin between the homopolymer and electrochromic layers.
