Abstract

The invention provides a preparation method of a graphene material and the graphene material. The preparation method comprises the following steps: providing a base material; filling the base materialwith graphene to form a graphene composite; adding a doping material for blocking a conductive path among graphene to the graphene composite, wherein the doping material and graphene are arranged atan interval in at least one direction of the graphene composite. In the embodiment, the doping material is added to the graphene composite, as the doping material and graphene are arranged at an interval in at least one direction of the graphene composite, the doping material can block the conductive path of the graphene, the conductivity of the graphene composite can be reduced, and the application range of the graphene composite is expanded.

Description

technical field [0001] The invention relates to the field of thermally conductive materials, in particular to a method for preparing a graphene material and the graphene material. Background technique [0002] In the prior art, the thermal conductivity of thermally conductive products is improved by adding graphene to the base material. Due to the good electrical conductivity of graphene itself, it has a certain impact on the insulation performance of heat-conducting products, thus limiting its application scenarios. Contents of the invention [0003] The object of the present invention is to provide a preparation method of graphene material and graphene material, so as to solve the problem in the prior art that the application scenarios of graphene material are limited due to the conductive properties of graphene. [0004] In order to achieve the above object, an embodiment of the present invention provides a method for preparing a graphene material, comprising: [0005...
