▎ 摘　　要

NOVELTY - A three-dimensional structured graphene oxide-polyaniline composite is obtained by dissolving aniline monomer in chloroform, forming an organic phase, dispersing graphene in an aqueous solution of sulfuric acid, obtaining an aqueous phase, providing a substrate at interface of upper organic phase and upper aqueous phase, soaking the substrate, performing insulation treatment, providing a counter electrode and a reference electrode, performing electrochemical deposition, placing resultant in an ice bath and processing at 0-2 degrees C and 0.02-2 mA/cm2 for 10-50 minutes. USE - Three-dimensional structured graphene oxide-polyaniline composite is used as capacitor electrode material. ADVANTAGE - The three-dimensional structured graphene oxide-polyaniline composite has excellent capacitance and cycle stability, and can be manufactured by simple and environmentally-friendly process. DETAILED DESCRIPTION - A three-dimensional structured graphene oxide-polyaniline composite is obtained by dissolving 110-250 parts mass aniline monomer in chloroform, forming an organic phase, dispersing 1-10 parts mass graphene in an aqueous solution of sulfuric acid having concentration of 1 mol/L, obtaining an aqueous phase, providing a substrate at interface of upper organic phase and upper aqueous phase, soaking the substrate, performing insulation treatment, providing a counter electrode and a reference electrode, performing electrochemical deposition, placing resultant in an ice bath and processing at 0-2 degrees C and 0.02-2 mA/cm2 for 10-50 minutes.
