Abstract
The application of solid polymer electrolytes as dual-function electrolyte/adhesive components in electrochromic devices and the preliminary characterization of the resulting prototype displays is described in this paper. An asymmetric device configuration, represented schematically as glass/ZnO:Ga2O3/WO3/polymer electrolyte/ZnO:Ga2O3/glass, was chosen. Electrolytes with compositions of n between 3 and 10, where n represents the molar ratio of poly(trimethylene carbonate), p(TMC), ((C = O) OCH2CH2CH2O), units per guest lithium ion, were prepared by solvent casting. The electrochromic switching performance was characterized as a function of salt type and salt concentration. The average transmittance in the visible region of the spectrum was above 63% for all the bleached samples characterized. After coloration the structures assembled with both p(TMC)(n)LiClO4 and p(TMC)(n)LiBF4 presented an average transmittance in the visible wavelength region above 39%.
