High-flux graphene-metal complex and preparation method thereof

The invention provides a high-flux graphene-metal complex and a preparation method thereof. The complex comprises a metal wire, wherein the outer side of the metal wire is coated with graphene; the metal wire forms a three-dimensional macroscopic body which can be bent or stereoscopically processed, and has the porosity of 90 to 95 percent; the preparation method of the high-flux graphene-metal complex comprises the following steps: firstly forming a dense graphene layer on the surface of a metal wire mesh; then producing a cylindrical structure part; or producing the metal wire mesh into thecylindrical structure part and then forming the dense graphene layer on the surface of the metal wire mesh; after stopping reaction, taking out the graphene-metal wire complex. According to the high-flux graphene-metal complex and the preparation method thereof, the graphene grows on the surface of the metal wire mesh in situ, the structure is firm and the utilization period is prolonged for by 2times; a lot of oil can be
