▎ 摘　　要

NOVELTY - The method involves adding oxidation graphene to non-proton and organic solvent to obtain a graphene dispersion. Copper powder or copper fiber is added to the graphene dispersant liquid, stirring to obtain uniform dispersion liquid. The dispersion solution is added by the oxidation graphene and the copper powder and copper fiber into the high-temperature reaction vessel, heating the reaction vessel out of the solvent to form a network structure, wrapping the copper solution or the copper fiber in the network. The organic solvent is removed in the composite material, sintering under an inert atmosphere to obtain the graphene -copper foam material. The sintered composite foam material is subjected to one-handed reduction and graphene reduction treatment. A high-conductivity graphene network structure is obtained. USE - Method for preparing graphene of composite porous copper foam. ADVANTAGE - The method enables playing the role of powder forming by the three-dimensional graphene network, at the same time, improving the porosity of the composite foam copper material, preventing excessive sintering, and greatly improving the corrosion resistance of the foam copper. DESCRIPTION OF DRAWING(S) - The drawing shows a scanning electron microscope graphene of the composite porous copper foam.
