摘要：
Graphene has a variety of excellent properties, however, it is easy to aggregate to restack into graphite by π-π stacking and van der Waals force. In order to solve the stacking problem and improve the applicability of graphene materials, graphene and its derivatives have been combined with magnetic nanoparticles to obtain new functional materials with high performance. Based on the recent internal and international research works, the preparation methods of magnetic graphene nanocomposites such as hydrothermal, solvothermal, chemical grafting and microwave-assisted methods are summarized. The application of magnetic graphene composite materials in the separation and enrichment of environmental samples, catalysis, corrosion resistance of coatings, wave-adsorbing material and energy area are introduced. Some problems of magnetic graphene composite materials, such as the tendency to agglomeration of magnetic particles, the verification of its biological safety and the reduction of adsorption sites led by graphene oxide reduction are pointed out. At present, the preparation technology of graphene (oxide) is improving and the most important research in the future is the surface modification of magnetic graphene, which can make the surface of graphene have more adsorption sites, and also lead to the more uniform morphology and distribution of magnetic nanoparticles on graphene surface, being conducive to the stable play of the functional properties of magnetic graphene. © 2022, Chemical Industry Press Co., Ltd.
