摘　　要：采用原位乳液聚合法制备了盐酸与十二烷基苯磺酸（DBSA）共掺杂聚苯胺／MWNTs复合材料。利用FTIR、TEM和TG等对复合材料的形貌和性能进行了表征。TEM结果表明苯胺共聚物包覆于碳纳米管表面，包覆厚度为10-20nm。复合材料在DMF、THF和氯仿中的溶解性大幅度提高，在520-750℃的热稳定性明显提高，包覆率为15．16％，电导率从聚苯胺的10^-7S／cm增大到10^-3S／cm。The MWNTs/polyaniline composites were prepared via in-situ emulsion polymerization using hydrochloric acid and dodecylbenzene sulfonic acid as dopants. The FTIR spectra, TEM and TGA were used to characterize the morphology and performance of the composites. The TEM results show that the surface of MWNTs are coated by polyaniline composites and the thickness of the coating layer is 10-20nm. The solubility is increased in DMF, THF and chloroform. The thermal stability of the composite is highly improved at 520-750℃ and the encapsulation rate is 15. 16 %. The conductivity of the sample is increased from 10^-7S/cm to 10^-3S/cm.
