| Description | 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 $Ag^{−1}$ are evaluated as 586 $Fg^{−1}$ and 611 $Fg^{−1}$, respectively. The values of energy density are 40 $Whkg^{−1}$ and 2094 $Wkg^{−1}$, whereas power density is recorded as 44 $Whkg^{−1}$ and 2160 $Wkg^{−1}$ 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. |
