中文摘要：

采用复合乳化剂微乳液法合成了导电聚苯胺（PANI）,以碳纸负载PANI为工作电极,考察了十二烷基苯磺酸钠（SDBS）和聚乙二醇辛基苯基醚（TX-100）的配比及复合乳化剂（E）和氧化剂（APS）用量对复合乳化剂微乳液法合成PANI的电化学性能的影响;通过对产物电导率和产率的对比分析,印证了PANI的电化学性能.结果表明,当SDBS与TX-100的质量比为1∶2,E与苯胺（An）单体的质量比为5∶3,APS与An的摩尔比为6∶5时,PANI的循环伏安峰电流、腐蚀电位和电导率均高于单组分乳化剂SDBS或TX-100微乳液法制备的PANI.

英文摘要：

The polyaniline（PANI） was prepared by microemulsion polymerization in the presence of compo-site emulsifier.The effects of the mass ratio of sodium dodecylbenzenesulfonate（SDBS） to Triton X-100（TX-100） and the amount of composite emulsifier（E） and oxidant（APS） on the electrochemical properties of PANI were discussed via cyclic voltammogram（CV） using the carbon paper loaded PANI as working electrode,and the characterization result of the electrochemical properties of the PANI was also proved by the contrast analysis of the conductivity and yield of PANI.The experimental results shows that when the mass ratios of SDBS to TX-100 and E to anilin（An） are 1∶2 and 5∶3,the molar ratio of APS to An is 6∶5,the properties of the PANI are the best;besides,the peak current of CV,the corrosion potential and conductivity of product are higher than those of the PANI synthsized by microemulsion polymerization in the presence of single emulsifier（SDBS or TX-100）.
