英文摘要：

The p-toluenesulfonic acid（TSA） doped nano-fibrous polyaniline（PANI） film was synthesized by pulse galvanostatic method（PGM）. The electrochemical activity and capacitance property of the PANI-TSA film were fine when it was prepared under the condition of ton ：toff of 30 ms ： 70 ms, average pulse current density of 0.5 mA/cm^2 and concentration ratio above 4 between TSA and aniline. A specific capacitance of 1 036 F/g could be obtained at discharge current density of 0.5 mA/cm^2. The electrochemical activity of the PANI-TSA film was fine in a wide pH range, the thermal stability was fine under 160 ℃. The SEM observation found that the nano-fibrous PANI doped with TSA had a length of about 1 - 2 μm and a diameter of about 150 nm.
