The invention discloses copper coated grid-type graphene, and further discloses a preparation method of the copper coated grid-type graphene. The preparation method comprises the steps that 1, the surfaces of graphene nanosheets are desensitized and inactivated, and the graphene nanosheets are punched in a vacuum punching bin of a transmission electron microscope, so that grids are formed; 2, trisodium citrate, sodium tetraborate and EDTA are added into a copper sulfate solution, and the pH value is adjusted to obtain a main salt mixed solution; 3, a catalyst, a reducing agent and a buffer agent are added into the main salt mixed solution, and the pH value is adjusted to obtain a mixed plating solution; 4, the grid-type graphene nanosheets are placed in the mixed plating solution, then, anadditive is added, the pH value is controlled to be 10-15, magnetic stirring, ultrasonic dispersion and filtration are conducted, and the grid-type graphene nanosheets are taken out; the grid-type graphene nanosheets are washed with deionized water to be neutral, drying is conducted, and the copper coated grid-type graphene is prepared. By means of the method, the plating effect and the electrical conductivity are obviously improved.
