Abstract

The electrochemical and photoelectrochemical behaviors of polythiophene nanowires prepared by templated electrodeposition in supercritical fluids were investigated. The polythiophene nanowires prepared showed sharp and strong capacitive redox waves in its cyclic voltammogram and excellent photocurrent responsivity in its cyclic voltammogram under photo-irradiation. These were better results compared to those obtained by the use of polythiophene films deposited on the flat disc electrode. This is mainly due to the fact that surface area of nanowires are much larger than that of flat films.
