NOVELTY - Preparation of composite material involves dissolving three-dimensional (3D) graphene oxide in deionized water and ultrasonically stirring for 10 minutes to obtain aqueous phase 3D graphene oxide solution, dissolving purified aniline in chloroform to form an oil phase, mixing oil phase and aqueous phase, reacting at 0-5 degrees C for 24 hours by interfacial polymerization to obtain oil-water interface with appearance of dark green solution, filtering, washing, drying at 60 degrees C for 12 hours to obtain graphene oxide/polyaniline nanowire composite material, dissolving nanowire composite material in deionized water and stirring in potassium permanganate and manganese (II) sulfate solution for 5 minutes to obtain mixture, transferring to autoclave and reacting to 180 degrees C for 4 hours, cooling to obtain mixed solution, adding sodium hydroxide solution to mixed solution, ultrasonically processing for 5 minutes, reacting at 180 degrees C for 2 hours, cooling, washing with deionized water, and drying. USE - Preparation of composite material. DETAILED DESCRIPTION - The mass ratio of purified aniline to three-dimensional graphene oxide is 0.1-4:1.
