Functionalization of wet-spun graphene films using aminophenol molecules for high performance supercapacitors

Abstract

Aminophenol isomer functionalized graphene film electrodes are fabricated with wet-spinning technology for supercapacitors. According to the different electrochemical mechanisms of aminophenol isomers on graphene, we optimize the conditions of o-aminophenol combined graphene, achieving a high specific capacitance of 636 F g⁻¹ and excellent cycling stability of 97% after 16 000 cycles.
