摘　　要：采用种子乳液聚合的方法制备了聚(苯乙烯-丙烯酸丁酯-丙烯腈)/聚苯胺(P(St-BA-AN)/PANI)核壳结构复合微球,对复合微球的形貌、结构、电性能和热性能进行了研究.结果表明,种子微球的粒径、形貌以及掺杂剂的种类对核壳结构复合物的电导率均有影响,并且其电导率随着苯胺加入量的增加而提高.TGA测试结果表明,在380℃以下P(St-BA-AN)/PANI复合物的热稳定性好于PANI.Poly（styrene-butyl acrylate-acrylonitrile）（P（St-BA-AN）） latex particles were successfully coated with polyaniline（PANI） by seeded emulsion polymerization.Morphology,structure,electrical and thermal properties of P（St-BA-AN）/PANI composites were studied.Conductivity of the core/shell composites was affected by morphology and diameters of P（St-BA-AN） seed microspheres,and type of doping agents.Data also indicated that conductivity of composites increased with increasing aniline content.TGA test found that the composites were stable at 380℃,indicating improved thermal stability.
