Abstract

The invention relates to a graphene/rare earth fluoride nanoscale composite material and an intercalation stripping synthesis method thereof. The graphene/rare earth fluoride nanoscale composite material is prepared from raw materials of a rare earth salt solution, expandable graphite, a surfactant solution and a fluorine source solution. The intercalation stripping synthesis method of the graphene/rare earth fluoride nanoscale composite material comprises the following steps of 1, taking the raw materials, 2, mixing the rare earth salt solution and the expandable graphite, and adding the surfactant solution and the fluorine source solution into the mixture with heating and stirring to obtain a substance A, and 3, washing the substance A, and then carrying out vacuum drying and calcination. The graphene/rare earth fluoride nanoscale composite material has the advantages that rare earth nanoscale crystal particles are inserted between the graphene sheet layers successfully and have consistent shapes and sizes of 2 nanometers to 50 micrometers; and the graphene/rare earth fluoride nanoscale composite material has peculiar physical, chemical and mechanical properties. The intercalation stripping synthesis method of the graphene/rare earth fluoride nanoscale composite material has the advantages of simple process, low cost, simple production equipment, high production safety, and good feasibility for industrialized production.

Description

technical field [0001] The invention relates to a graphene / rare earth fluoride nanocomposite material and a synthesis method thereof. Background technique [0002] Graphene has sp 2 A two-dimensional carbon atom crystal of hybrid orbitals, which is currently the thinnest material in the world - a material with a thickness of one atom. Graphene has excellent crystallinity and unique electronic, thermodynamic, and mechanical properties, and can be applied to many advanced materials and devices, such as thin film materials, energy storage materials, liquid crystal materials, mechanical resonators, etc. Therefore, more and more scholars are involved in the research on the synthesis and properties of graphene composites. At present, the synthesized graphene / inorganic nanocomposites mainly include graphene / silicon dioxide, graphene / titanium dioxide, graphene / noble metal and graphene / tungsten carbide. [0003] The synthesis method of graphene nanocomposites is mainly to composit...
