采用循环伏安法在不锈钢网上合成了导电聚苯胺(PANI)。研究了合成扫速分别为5,10,20,50,100mV/s时聚苯胺电极的性能。结果表明,扫速为5mV/s时生成的聚苯胺膜孔隙最小,比表面积最大,电阻最小,具有最好的电容性能,在0.1A/g和1A/g充放电电流密度下,其比容量分别达860F/g和485F/g。
Cyclic voltammetry (CV) was used to deposit polyaniline (PANI) electrode on stainless steel mesh and the performance of various PANI film deposited with scanning rates of 5, 10, 20, 50 and 100 mV/s were conducted. The results show that the PANI electrode grown with 5 mV/s has the largest specific surface area and the lowest resistance and the best electrochemical performance among those electrodes. When the charge-discharge current density is 0.1 A/g, the specific capacitance can reach 860 F/g. And when the current increase to 1 A/g, the specific capacitance is about 485 F/g.
