Construction of smart window for saving energy

Transparent, conductive and uniform carbon nanotube (CNT) films have been prepared and used as electrodes of the electrochromic devices of polythiofen. polythiofen films on both (CNT) and the widely used Tungsten oxide (WO3) electrodes showed similar electrochemical and spectroelectrochemical properties. However, (CNT) electrodes exhibited much higher electrochemical stability than WO3 in aqueous acidic electrolytes. The performances of the electrochromic devices with (CNT) electrodes exhibited slight decrease upon voltage switching while those of the devices with WO3 electrodes decreased drama-cally. A.er 2/// cycles, the electrochromic devices with (CNT) electrodes showed much larger optical contrast and shorter switching time than those of the devices with WO3 electrodes.
