NOVELTY - Manufacture of structure-controllable three-dimensional graphene porous material involves constructing (AA) a CAD mold having a three-dimensional porous structure, preparing porous metal structure having corresponding shape by additive manufacturing technique, heating at 900-1500?C under protective atmosphere of an inert gas for 4-24 hours, cooling to room temperature, performing sand blasting and ultrasonic washing to obtain a metal template (BB), growing a graphene film (CC), preparing etching agent, dissolving the metal template by fluxing at 60-90 degrees C, washing and drying. USE - Manufacture of structure-controllable three-dimensional graphene porous material (claimed). ADVANTAGE - The three-dimensional graphene porous material having precise shape is produced quickly. DETAILED DESCRIPTION - Manufacture of structure-controllable three-dimensional graphene porous material involves constructing a CAD mold having a three-dimensional porous structure, preparing a porous metal structure having corresponding shape by an additive manufacturing technique, heating at 900-1500?C under protective atmosphere of an inert gas for 4-24 hours, cooling to room temperature, performing sand blasting and ultrasonic washing to obtain a metal template, growing a graphene film on the metal template by chemical vapor deposition method, preparing 1-3 mol/L etching agent, dissolving the metal template by fluxing at 60-90 degrees C, washing and drying. The metal structure is formed using metal powder having average particle diameter of 5-50 mu m and containing nickel, copper, iron and cobalt.
