a SEM of pure PANI fibers (PANI-F). b SEM of GO and PANI composites with GO weight percentage of 10% (PAGO 10). c SEM of GO and PANI composites with GO weight percentage of 50% (PAGO 50). d SEM of GO and PANI composites with GO weight percentage of 80% (PAGO 80). e Cyclic voltammograms recorded in 2 M H2SO4 by using different composites coated with glassy carbon electrode as working electrode, a Pt sheet as counter electrode, and a AgCl/Ag electrode as reference electrode. The scan rate is 100 mV/s; f Charge/discharge cycling curves of different composite electrodes at a current density of 0.1 A/g. Reprinted with permission from [41].
