NOVELTY - The preparation of polypyrrole nanowire array/graphene sheet/manganese oxide composite material, involves (1) dissolving three-dimensional graphene oxide in deionized water, ultrasonically reacting for 10 minutes to obtain aqueous phase, (2) dissolving purified pyrrole in chloroform to obtain oil phase, mixing with aqueous phase, carrying out interfacial polymerization at 0-5 degrees C for 24 hours, filtering, washing and drying at 60 degrees C for 12 hours to obtain graphene oxide/polypyrrole nanowire composite material, (3) dissolving graphene oxide/polypyrrole nanowire composite in deionized water, adding potassium permanganate solution and manganese(II) sulfate solution, stirring, ultrasonically reacting for 5 minutes, heating at 180 degrees C for 4 hours and cooling to obtain mixed solution, (4) adding sodium hydroxide solution to mixed solution, ultrasonically reacting for 2 hours at 180 degrees C, cooling, washing with deionized water and drying. USE - Preparation of polypyrrole nanowire array/graphene sheet/manganese oxide composite material. DETAILED DESCRIPTION - The mass ratio of purified pyrrole and three-dimensional graphene oxide is (0.1-4):1. The mass ratio of manganese(II) sulfate and sodium hydroxide is 3:5. The mass ratio of manganese(II) sulfate and potassium permanganate is 9:1. The mass ratio of manganese oxide and three-dimensional graphene oxide is (0.05-0.5):1. The mass ratio of manganese dioxide and trimanganese tetroxide is 1:1.
