NOVELTY - Preparation of graphene-three-dimensional polypyrrole skeleton sponge involves washing nickel foam with absolute ethanol, acetone, and deionized aqueous solution, drying, cutting cleaned nickel foam to required size, placing it in working electrode of 0.3 M sodium perchlorate solution, and 5% pyrrole solution, using platinum wire as counter electrode, and calomel electrode as reference electrode, taking out electroplated polypyrrole-nickel foam black compound, washing with deionized water, removing unoxidized pyrrole monomer on surface, cleaning compound after placing in 1 M iron(III)chloride solution for etching, washing with deionized water, and drying at room temperature. USE - Preparation of graphene-three-dimensional polypyrrole skeleton sponge. ADVANTAGE - The preparation method is simple.
