Fig. 4. Supercapacitor characterization. (a) Comparative CVs of carbon, PANI and carbon–PANI (composition S3) samples at a scan rate of 5 mV s–1. (b) Comparison of the specific capacitance performances of carbon, PANI and carbon–PANI nanocomposites (S1–S5) at various time intervals. (c) Variation of capacitance with scan rate for carbon, PANI and carbon–PANI nanocomposite (composition S3) samples.
