Preparation method and application of three-dimensional pleated graphene heat-dissipating slurry

The invention relates to the field of nanotechnology, in particular to a preparation method and application of a three-dimensional pleated graphene heat-dissipating slurry. The three-dimensional pleated graphene heat-dissipating slurry is prepared according to the following steps: enabling thin graphene to form porous graphene aggregate by using a solvent, heating the porous graphene aggregate, rapidly cooling the aggregate after completion of heating to obtain a three-dimensional pleated graphene block, crushing the three-dimensional pleated graphene block to obtain three-dimensional pleatedgraphene, and compounding the three-dimensional pleated graphene with a monomer of a polymer to obtain the heat-dissipating slurry. Through use of the three-dimensional pleated graphene as a componentof heat-dissipating coating, pleats formed by a graphene material effectively increase the surface area of a composite material and can effectively improve the heat-dissipating efficiency, so that the graphene heat-dissipatin
