Preparation method for polyaniline-coated graphene loaded copper-nickel solid solution composite material

The invention discloses a preparation method for a polyaniline-coated graphene loaded copper-nickel solid solution composite material, and belongs to the technical field of electrode materials of supercapacitors. The invention solves the technical problem that the graphite oxide is not suitable for being used as the electrode material of the supercapacitor due to the defects of low specific capacitance value and the like. Firstly, a graphene/copper-nickel solid solution composite material is prepared by adopting a microwave method, and a polyaniline/graphene/copper-nickel solid solution core-shell type composite material is prepared by adopting an in-situ polymerization method. The graphene, the copper-nickel solid solution and the polyaniline in the polyaniline/graphene/copper-nickel solid solution composite electrode material prepared by adopting the in-situ polymerization method have a synergistic effect; when the doping amount of the graphene/copper-nickel solid solution is 20 wt%of polyaniline, the speci
