Abstract

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).
