摘　　要：在导电聚合物中,聚苯胺(PANI)由于具有很高的导电性、热稳定性、容易制备等性质而受到了格外的关注。但由于PANI分子链骨架的刚性较强,分子间相互作用力大,导致其溶解、加工性能较差,对其实际应用造成了极大限制。为了改善提高聚苯胺的溶解性和加工性能,大量的研究人员对PANI展开了深入的研究。本文介绍了采用乳液聚合法和反相乳液聚合法合成聚苯胺,;介绍了聚苯胺苯环上和氨基氮上取代或改性两大类衍生物,分析了聚苯胺及其衍生物的结构,对其研究和应用作了简要综述。。Among the conducting polymers,polyaniline（PANI）attracted great interest because of its reasonably good conductivity,stability,easy preparation and so on.However,it was difficult to dissolve and process because of the rigidity of the its molecular chain and strong intermolecular interaction,which limited its practical application.Therefore,many potential applications of PANI still remain unexploited.Efforts were taken to improve the processability and dissolution of PANI.The synthesis of PANI by the emulsion/inverted emulsion polymerization pathway was discussed,and the research and application of PANI ramification including benzene ring and amino nitrogen substituted PANI were introduced.The structural characteristics of PANI ramification were analyzed.
