Electrochemical properties of dodecylbenzenesulfonic acid doped polyaniline film in various organic electrolyte solutions

Summary form only given. For an electroactive polyaniline the microstructure formation of the film and the role of surfactant in electrochemical redox process were investigated by cyclic voltammetry, ac impedance spectroscopy and x-ray diffraction pattern. Polyaniline doped with surfactant was prepared by emulsion polymerization in the presence of dodecylbenzene sulfonic acid (PAn-DBSA). Electrochemical reversibility, cyclic stability, capacitance, and redox reactivity were studied in various organic electrolyte solutions containing LiClO/sub 4/ and their properties were explained by the mobility of Li/sup +/ cations for charge neutrality in the film. According to the results of X-ray diffraction patterns, the electrochemical redox process changed the microstructure of PAn-DBSA film and the DBSAs were stacked in double layer structure in tile film.
