QM 35553 Solid State Electrochromic Devices An electrochromic device which comprises two conductive electrodes separated by a solid electrolyte and an electrochromic material capable of reversible electrochromic interaction with activating electrons and/or ions furnished to it by, or by it to, the rest of the device under the influence of an electrical potential applied across the electrodes, characterised in that the solid electrolyte in the device comprises: a) a matrix of optionally cross-linked main polymer chains, having side-chains linked to the main polymer chains, which side chain comprise polar groups, b) an ionised ammonium or alkali metal salt dissolved in the matrix and/or liquid, and c) an optional polar aprotic liquid dispersed in the matrix, and a process for the preparation thereof.
