Graphene heat conduction film, preparation method thereof and thermal interface material
The invention relates to the technical field of heat conduction materials, and particularly discloses a graphene heat conduction film, a preparation method thereof and a thermal interface material. The preparation method of the graphene heat-conducting film specifically comprises the following steps: coating a porous substrate with graphene oxide mixed slurry, and performing carbonization and graphitization to obtain the graphene heat-conducting film, the graphene oxide mixed slurry comprises graphene oxide with different oxidation degrees. The thermal interface material at least comprises a first graphene heat-conducting film, a second graphene heat-conducting film and a nanoparticle layer which is stacked between the first graphene heat-conducting film and the second graphene heat-conducting film and used for anchoring the first graphene heat-conducting film and the second graphene heat-conducting film, and an adhesive is also arranged between the first graphene heat-conducting film and the second graphene heat-conducting film. The graphene in the prepared graphene heat-conducting film is arranged in the longitudinal direction, has good heat-conducting and electric-conducting performance in the longitudinal direction, and can effectively solve the problem of longitudinal heat conduction of an interface.
