NOVELTY - Preparing graphene reinforced phase comprises e.g. placing copper foil in a reaction chamber, growing graphene on copper foil by chemical vapor deposition method, where graphene is in monolayer microchip state to obtain graphene/copper structures on copper foils, removing copper foil and placing a piece of copper foil to obtain graphene/copper in ferric chloride solution, removing copper foil from corrosion to obtain ferric chloride and copper(II) chloride solutions, and floating graphene microflake in solution and then adding dispersing agent into the solution of graphene microplate. USE - The method is useful for preparing graphene reinforced phase.
