ABSTRACT:
An electrochromic glass of a size suitable to be used with advantage in automobile or building applications, made from two sheets of glass and as external walls, two transparent conductor layers and two electrodes as the system's active elements and an electrolyte polymer. The active electrode is made of tungsten oxide, whereas the active electrode is made of vanadium oxide or a suitable mixture of vanadium oxide and molybdenum oxide. The electrolyte polymer is obtained by dissolving lithium perchlorate in a suitable solution of propylene carbonate and polymethylmethacrylate. A suitable reference electrode keeps the system under control. The complex formed as above is capable of rapidly becoming dark or transparent under the action of an electric field.
