GCD curves of PEDOT/GO (a) electropolymerized at 1.2 V and 10 min with different concentrations of GO (0.5 mg/mL, 1.0 mg/mL, 1.5 mg/mL, and 2.0 mg/mL), (b) electropolymerized at 1.2 V containing 1.0 mg/mL GO with different electropolymerization times (1 min, 5 min, 10 min, 15 min, and 30 min), (c) electropolymerized at 1.2 V and 10 minutes containing 1.0 mg/mL GO with different current densities (1.0 A/g, 2.0 A/g, 3.0 A/g, 4.0 A/g, and 5.0 A/g).
