Abstract
An attempt has been made to investigate the electrochromic properties of polycarbazole (PCARB) films. Both the electrochemical current respo nse and optical transmittance of an electrochromic cell fabricated usi ng PCARB electrochemically deposited on an indium tin oxide (ITO) glas s as an anode and platinum as a cathode have been experimentally measu red, Current transients observed for colouration and decolouration of PCARB films have been analysed to delineate the mechanism of switching reaction in these semiconducting PCARB films. The response times in v arious media range from 87 to 208 ms and the life cycle of such PCARB electrodes is about 10(4) cycles.
