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)的配比及其复合乳化剂(E)和氧化剂(APS)用量对复合乳化剂微乳液法合成PANI电化学性能(循环伏安、塔费尔)的影响;通过对产物电导率和产率的对比分析,印证了PANI电化学性能表征结果的有效性。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1.2时,PANI的各项性能指标达到最好,且产物的循环伏安峰电流、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。

Abstract: The polyaniline(PANI) was prepared by microemulsion polymerization in the presence of composite emulsifier. The effects of the mass ratio of sodium dodecylbenzenesulfonate (SDBS) to Triton X-100(TX-100) and the amout of composite emulsifier(E) and oxidant(APS) on the electrochemical properties(cyclic voltammogram, tafel) 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 showed that when the mass ratio of SDBS to TX-100 and E to anilin(An) was 1/2 and 5/3, the molar ratio of APS to An was 1.2, the properties of the PANI were the best; besides, the peak current of CV, the corrosion potential and conductivity of product were higher than PANI synthsized by microemulsion polymerization in the presence of single emulsifier (SDBS or TX-100).
