✦ Synopsis

Abstract

Graphene oxide (GO) nanosheets are readily reduced by aniline above room temperature in an aqueous acid medium, with the aniline simultaneously undergoing oxidative polymerization to produce the reduced graphene oxide‐polyaniline nanofiber (RGO‐PANi) composites. The resulting RGO‐PANi composites and RGO (after dissolution of PANi) were characterized by XPS, XRD analysis, TGA, UV–visible absorption spectroscopy, and TEM. It was also found that the RGO‐PANi composites exhibit good specific capacitance during galvanostatic charging–discharging when used as capacitor electrodes. magnified image

Graphene oxide (GO) is reduced and functionalized with primary amine by a one-pot solvothermal process using ethylene glycol as solvent and ammonia water as nitrogen precursor at 180 °C for 10 h. The reaction is featured by nucleophilic substitution of -COOH and C-O-C groups by the ammonia radicals.
