摘要: 在众多的导电聚合物中,聚苯胺(PAn)被认为是最具应用前景的导电聚合物[1].本征态PAn的电导率约10-13S/cm数量级,呈电绝缘性.当用质子酸对PAn掺杂后,电导率达到5~10S/cm,可实现从绝缘体到导体的转变.

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.
