The emeraldine base form of polyaniline (PANI) can be doped by a photo-induceddoping method. In this method a copolymer of vinylidene chloride and methyl acrylate(VCMAC) was used as photo acid generator which can release proton when it is exposedto ultraviolet light (λ= 254 nm). The structure of PANI-VCMAC system before and afterirradiation was characterized by elemental analysis, IR, XPS, and SEM images. Resultsobtained indicate that the photo-induced doping characteristics, such as doping position and type of charge carriers,are similar to that of PANI doped with HCl.The poor room-temperature conductivity (～10-5S/cm) of PANI-VCMAC system after irradiation may be due to low doping degree (～pH=3)and the difference in morphology as compared with PANI-HCl film.
