DETAILED DESCRIPTION - Preparing graphene oxide-polyaniline composite electrode material with three-dimensional structure, involves dissolving aniline monomer in chloroform to form an organic phase. The graphene oxide is dispersed in sulfuric acid to form an aqueous phase. A substrate is arranged at the interface of the organic phase of the upper aqueous phase of the upper layer. One side of the substrate is immersed in the lower organic phase and is subjected to an insulating treatment, and the other side of the substrate is immersed in the organic phase. The upper later of aqueous phase is used in the ice bath under the condition of electrochemical constant current method, and the reaction system of the organic phase of the upper layer of the upper aqueous phase is used as the working electrode. The counter electrode and the reference electrode are arranged in the upper aqueous phase. The graphene-polyaniline composite electrode material is co-deposited on the substrate.
