The electrochemical deposition of the composites polyaniline (PANI):polypyrrole (PPy)/activated carbon (AC) and polyaniline (PANI): 3, 4-polyethylenedioxythiophene (PEDOT)/AC films is carried out in this work. The electrochemical character of the fabricated samples is investigated via cyclic voltammetry (CV), galvanostatic charge-discharge (GCD) and electrochemical impedance spectroscopy (EIS) using a three-electrode setup. The values of the specific capacitance of the composites PANI:PPy/AC and PANI:PEDOT/AC at a current density of 1 Ag are evaluated as 586 Fg and 611 Fg, respectively. The values of energy density are 40 Whkg and 2094 Wkg, whereas power density is recorded as 44 Whkg and 2160 Wkg for respective composites PANI:PPy/AC and PANI:PEDOT/AC. Moreover, the respective composites appeared to retain cyclic stabilities of 92% and 90%. This study points to the potential of the prepared composites for application as electrodes in supercapacitors.
本工作开展了聚苯胺（PANI）：聚吡咯（PPy）/活性炭（AC）和聚苯胺（PANI）：3,4 - 聚乙撑二氧噻吩（PEDOT）/AC复合薄膜的电化学沉积。采用三电极装置，通过循环伏安法（CV）、恒电流充放电（GCD）和电化学阻抗谱（EIS）研究了制备样品的电化学特性。在电流密度为1 Ag时，复合材料PANI:PPy/AC和PANI:PEDOT/AC的比电容值分别评估为586 F/g和611 F/g。对于复合材料PANI:PPy/AC和PANI:PEDOT/AC，能量密度值分别为40 Wh/kg和2094 Wh/kg，而功率密度分别记录为44 W/kg和2160 W/kg。此外，相应的复合材料似乎分别保持了92%和90%的循环稳定性。该研究指出了所制备的复合材料作为超级电容器电极应用的潜力。
