The invention relates to a graphene-based novel material and a chemical vapor deposition preparation technology thereof, in particular to graphene foam with a three dimensional fully connected network and a macroscopic quantity preparation method thereof. The method is suitable for a mass preparation of the graphene foam with high qualities. Three dimensional connected graphene can grow by catalytic cracking of carbon source gases on the surface of a three dimensional porous metal through the chemical vapor deposition technology, and a porous foam-shaped graphene three dimensional macroscopic body can be obtained after a porous metal base is removed by dissolving subsequently. According to the graphene foam with the three dimensional fully connected network and the macroscopic quantity preparation method thereof, a simple template replication method is used for preparing the three dimensional connected graphene macroscopic body, and the method has the advantages that the operation is simple and convenient, the rate of production is high, and the adjustment and control of the structure are easy. The graphene foam forms the fully connected network in a seamless connection mode, has a low density, a high porosity and specific surface area and excellent capabilities of charge conduction and heat conduction and establishes a foundation for applications of graphene in fields of electric conduction, thermally conductive composite materials, electromagnetic shielding, wave absorbing, catalysis, sensing and energy storage materials and the like.
