Abstract

Both the PANI(polyaniline) film and TiO 2_PANI composite film on the PATP(p_aminothiophenol)/Au substrate were obtained under different preparation condition by electrochemical methods, and their photoelectrochemical performances were also studied.The results showed that the photoelectrochemical performances of the films depend deeply on the comditions of preparation.The self_assembling of PATP favors the adhesion of PANI.The partially_oxidized PANI has a greater photoelectrochemical response than that of the reduced PANI and oxidized PANI.There is an optimum of film thickness for the photoelectrochemical performance of PANI film.Heat treating is in favor of the photoelectrochemical performance of TiO 2,but decreases the photocurrent response of PANI film.There is an optimal temperature for the photoelectrochemical performance of TiO 2_PANI composite film.Optimizing the preparation condition can improve the photoelectrochemical performances of both the PANI film and TiO 2_PANI composite film.
