Surface nano-nickel particle modified graphene nano material and preparation method thereof

The invention discloses a surface nano-nickel particle modified graphene nano material and a preparation method of the nano material, belonging to the field of nano material preparation technology. The preparation method can be used for preparing surface nano-nickel particle modified graphene by the steps of preparation of graphite oxide, preparation of graphene oxide and pretreatment. According to the invention, the surface nano-nickel particle modified graphene is prepared by a chemical plating method, so that the particle size and the crystal form of surface nano-nickel particles can be effectively controlled, and the graphene oxide part can be reduced when metal particles are deposited; and graphene sheet layers are prevented from being stacked again by the deposition of nickel particles on the surface of the graphene; and the graphene has excellent soft magnetism so as to be magnetized under the minimal additional magnetic field.
