Layered polyaniline/graphene film from sandwich-structured polyaniline/graphene/polyaniline nanosheets for high-performance pseudosupercapacitors

Abstract

Binder-free layered graphene/polyaniline composite supercapacitor film was prepared by an environmentally friendly route. It exhibited 384 F g⁻¹ at 0.5 A g⁻¹ and 84% capacitance retention over 1000 cycles.
