A new doping method for conductive polymers was investigated. Using a photo acid generator (PAG) as a doping precursor gave the carrier concentration control and thereby good electrical conductivity of the polymers after UV exposure. By this photo doping method with PAGs, a homogeneous film of conductive polymer could be prepared without aggregation and de-doping at the film. It was also effective for composite materials comprised of conductive polymers and CNT to perform much higher conductivity compared to non-doping material. The composite materials showed a good power factor as an organic thermoelectric material.
