Microcosmic Structure of Doped Polyaniline Synthesized by Emulsion Polymerization

Abstract

Abstract: Using dodecylbenzene sulphonic acid(DBSA) as emulsifier and doping agent, polyaniline(PAn) emulsion was polymerized in a wateroil twophase system, a PAn with high solubility and conductivity was obtained. The structure of the product was studied by using XRD and TEM. The results showed that, the conductive PAn polymerized by this method displayed a higher crystallinity. Afibril micromorphology was observed by the transmission electron microscopy. The effect of macromolecular conformation of PAn on the absorption spectra was discussed.

Key words: Conductive polymer, Polyaniline, Emulsion polymerization, Doping
