More Information
Summary:The invention provides a method for preparing a graphene material and the obtained graphene material. The method comprises the following steps: carrying out melt blending and cooling molding on a graphite material and a high-molecular polymer, stretching a molded composite material by utilizing stretching equipment, melting and stirring the deformed composite material, and then cooling and molding. Repeating the melting and stretching processes for multiple times to obtain a compound; and treating the compound with a solvent to obtain the graphene material, the solvent is dissolved in the high-molecular polymer; the method for preparing the graphene material through stripping in a multi-time stretching mode is simple and easy to operate, and the prepared graphene material shows specific high thermal conductivity, high electrical conductivity and excellent mechanical properties of graphene, can be used as a precursor of a thermal management material, and can also be used as a carrier or filler to be widely app
