摘　　要：采用过硫酸铵(APS)为氧化剂,在十二烷基苯磺酸(DBSA)微胶束中用化学氧化法制备纳米棒状和球形聚苯胺;DBSA既起乳化剂也起掺杂剂的作用,并用红外光谱(FT-IR)、紫外光谱(UV-vis)、X-射线衍射(XRD)和扫描电镜(SEM)对合成的聚苯胺进行了表征。不同的聚苯胺后处理方式对制备的聚苯胺/水性环氧树脂复合涂层电导率和聚苯胺分散有明显的影响;研究了这些涂膜的耐盐水性能。该复合涂料的表面电导率最大值为10-5S/cm,其他性能满足使用要求。Rod shaped and spheric polyaniline （PANI） were prepared with ammonium persulfate （APS） as oxidant in micellar solution of dodecylbenzene sulfonic acid （DBSA） by chemical oxidative polymerization. DBSA was used to play both the roles of emulsifier as well as doping agent. The PANI were characterized by FTIR, UV - vis, XRD and SEM. The after - treatment method of PANI showed a significant effect on the morphology of PANI dispersed in waterborne epoxy matrix and conductivity of the hybrid coatings. The salt water resistance of the composite coatings was studied. The maximum value of the conductivity reached 10^-5 S/cm, and the other chemical and physical properties can meet the requirement.
