1. A laminated graphene heat sink comprising:
a base plate and a plurality of fins extending from the base plate;
wherein the base plate and the fins comprise a plurality of layers of graphene film reaching from a bottom surface to a top surface of the heat sink, each layer of graphene film being separated from an adjacent layer of graphene film by an adhesive layer, and each layer of graphene film having an anisotropic thermal conductivity, and
wherein each adhesive layer further comprises a first layer of nanoparticles arranged at a surface of a first graphene film and a second layer of nanoparticles arranged at a surface of a second graphene film adjacent to the first graphene film, wherein the nanoparticles are embedded in the adhesive.
