The research of graphene and its composites is an important frontier and hot topic in materials science. Aimed at its defects in structural design, controlled preparation and comprehensive performance utilization, this project study preparation, structural control and adsorption properties of graphene / carbon foam composite, which is based on the application prospect in adsorption field of mesophase pitch based carbon foam and the excellent adsorption performance of graphene. Graphene is prepared by oxidation-reduction method and assembled into three-dimensional network structure, then this structure is intermixed with mesophase pitch to prepare graphene / carbon foam composites. The design and control theories of three-dimensional graphene network structure are established, the matching problem of graphene network structure and carbon foam matrix is solved, the influence of graphene / carbon foam composite organization and structure on the adsorption properties is revealed, the adsorption mechanism of graphene / carbon foam composite in multiphase medium aimed at heavy metals, organic pollutants and atmospheric pollutants is established. Through the synergistic effect between three-dimensional graphene network structure and foam carbon, the adsorption performance of carbon foam is greatly improved, which is of great theoretical significance and practical value for promoting the wide application and environmental protection of graphene and its new functional carbon materials.
