Abstract

A series of polyaniline (PANI) with different HCl/aniline and DBSA/aniline molar ratio was synthesized in this paper. The structure of PANI was characterized using IR spectroscopy. The effect of pH, thermal stability and photothermal conversion properties of PANI were investigated. The results showed that the IR spectrum presented typical absorption peaks of PANI-ES. The pH had a big influence on the optical property of PANI. The PANI had high thermal stability in all HCl/aniline molar ratio. The molar ration of DBSA/aniline can influence the photothermal conversion of PANI, whereas the doped PANI showed better photo thermal conversion efficiency than that of dedoped PANI.
