摘要
A gelatin-based electrolyte has been developed and characterized by impedance spectroscopy and thermal analysis. These electrolytes are promising materials to be applied in electrochromic devices because gelatine is a material available in nature, it is cheap, easy to handle and to prepare. In this study the characterization of a solid-state electrochromic device based on gelatin is reported and results obtained suggest that this electrolyte is very attractive for electrochemical device applications. Gelatin-based electrolytes were successfully used in the assembly of prototype electrochromic devices (ECDs) and exhibited good optical density. The ECD display incorporating gelatine I and gelatine II samples presented in the visible region an average transmittance above 68% in the bleached state. After coloration the structure assembled with gelatine I composition presented an average transmittance in the visible wavelength region above 21% and 36% for gelatin II. (C) 2009 Elsevier B.V.
