Study of electrochromic devices with nanocomposites polymethacrylate hydroxyethylene resin based electrolyte

Abstract

This paper reports the application of a polymethacrylate hydroxyethylene resin based electrolyte in electrochromic (EC) devices. The electrolyte is characterized by electrochemical impedance spectroscopy, visible spectroscopy, TGA, DSC, and DRX and tested as an ionic conductor in an EC device with the following configuration: Substrate/IZO/WO₃/Polymer Electrolyte/(CeO₂)TiO₂/IZO/Substrate. The electrolyte presents an ionic conductivity of 10⁻⁷ S/cm at room temperature and TGA analysis show that electrolyte is thermally degraded at 200°C. The EC device based on this polymethacrylate hydroxyethylene resin electrolyte system shows memory effect and exhibits an excellent optical density. Copyright © 2011 John Wiley & Sons, Ltd.
