Abstract

Polyaniline nanofibers were used to produce a flexible supercapacitor electrode with a specific capacitance of 235 F g⁻¹. Cycle life and energy density were enhanced after encapsulating the polyaniline nanofiber electrode in Nafion. A specific capacitance of 195 F g⁻¹ was obtained over 10,000 charge–discharge cycles.

A fully flexible, stand alone capacitor comprising two polyaniline nanofiber based electrodes and a PVDF separator was constructed. An initial specific capacitance of 125 F g⁻¹ (100 mV s⁻¹) was obtained. This decreased to 95 F g⁻¹ over 10,000 cycles.
