NOVELTY - Immersion method for preparing graphene/copper composite material, where solid carbon source is loaded on copper surface, involves preparing flaky copper powder particles by adding atomized copper powder and steel balls to a ball mill jar, filling alcohol for wet grinding, and vacuum drying, dissolving poly(methyl methacrylate)(PMMA) in dimethylformamide or acetone solution, immersing sheet-like copper powder in the mixed solution, carrying out hydrothermal or suction filtration, drying, and thermally reducing PMMA-copper powder in reduction tube furnace. USE - Immersion method for preparing graphene/copper composite material, where solid carbon source is loaded on copper surface (claimed). ADVANTAGE - The method ensures preparation of graphene/copper composite materials with different matrix by simple process. DETAILED DESCRIPTION - Immersion method for preparing graphene/copper composite material, where solid carbon source is loaded on copper surface, involves preparing flaky copper powder particles by adding atomized copper powder and steel balls in mass ratio of 1:15 to a ball mill jar, filling alcohol for wet grinding for 4 hours, and vacuum drying, dissolving poly(methyl methacrylate) (PMMA) in dimethylformamide or acetone solution, immersing sheet-like copper powder in the mixed solution, stirring for 6 hours, evaporating to dryness, carrying out hydrothermal reaction or suction filtration and drying to obtain a uniform loaded PMMA/copper composite powder, carrying out thermal reduction of PMMA/copper composite material by loading PMMA-copper powder into reduction tube furnace, and maintaining at a temperature of 1000 degrees C under reducing atmosphere of hydrogen.
