Conductive polyaniline (PANI) was prepared by sanding method for the first time. The effects of sanding speed, reaction time, the concentration of HCl, sodium dodecyl benzene sulfonate (SDBS) and ammonium persulfate (APS) on the redox performance and conductivity of PANI were discussed by cyclic voltammetry and standard four-probe method, and the structure of PANI was characterized by FT-IR. The results indicated that the optimal properties of PANI were achieved when the sanding speed was 400 r/min, the reaction time was 2 h, the molar ratio of HCl to An was 4∶1, the molar ratio of SDBS to An was 1∶1 and the molar ratio of APS to An was 0.8∶1. The structure and electrochemical properties of PANI prepared by sanding method were very close to PANI synthesized by emulsion method. But the production cost and the environmental advantage of sanding method was significant due to the reaction time was only one third of emulsion method and the total amount of water was only one half of emulsion method.

Key words: polyaniline (PANI), sanding method, electrochemical property
