▎ 摘　　要

NOVELTY - Preparing polyaniline nanowire-graphene oxide/graphene composite material comprises (i) taking graphite paper as an anode and stainless steel as cathode, performing electrochemical peeling in an oxidizing electrolyte to obtain graphite paper with surface layer containing graphene oxide or taking graphite paper as an anode and stainless steel as cathode and performing electrochemical peeling in the non-oxidizing electrolyte to obtain the graphene-containing graphite paper on the surface; and (ii) taking graphite paper containing graphene oxide or graphene on the surface layer as the anode and stainless steel as the cathode and performing electrochemical deposition in an acidic electrolyte containing aniline. The oxidizing electrolyte comprises at least one of nitric acid, sulfuric acid and/or perchloric acid. The non-oxidizing electrolyte comprises at least one of sulfuric acid, phosphoric acid, sodium hypophosphite, sodium dihydrogen phosphate and/or sodium sulfate. USE - The method is useful for preparing polyaniline nanowire-graphene oxide/graphene composite material is useful as cathode material for seawater batteries or zinc ion batteries (all claimed). ADVANTAGE - The method: generates polyaniline nanowires in situ by electrochemical deposition with high density and uniform diameter distribution; and prepares composite material as cathode material for seawater batteries or zinc ion batteries without separation to obtain seawater or zinc ion batteries with high energy density. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for polyaniline nanowire-graphene oxide/graphene composite material, prepared as mentioned above.
