Facile Synthesis of Conducting Hydrogels Based on Polyaniline Fiber and Graphene Oxide for Application in all-solid-state Supercapacitors

摘要

A new conducting hydrogel based on graphene oxide (GO) and polyaniline (PANi) fibers was facilesynthesized (denoted as GO/SA/PANi) for application in flexible all-solid-state supercapacitor device.Taking advantage of the synergistic effects of the components and synthesis strategies, the conductinghydrogels showed high mechanical stability and conductivity (16.8 S/m). Furthermore, thesupercapacitor based on GO/SA/PANi exhibited high area specific capacitance (2.3 F/cm 2 at 0.5mA/cm 2 ). This study not only represents a novel conducting hydrogel for application in all-solid-statesupercapacitor with high performance, but also provides a new method for enhancing capacitance andmechanical stability of conducting hydrogels.
