NOVELTY - Manufacturing a graphene based heat sink involves providing (100) a first graphene film, providing (102) a second graphene film, arranging (104) a layer of nanoparticles on a surface of the first and second graphene film, where the nanoparticles are configured to improve an adhesion strength between the first and second graphene films, arranging (106) an adhesive on the first graphene film, attaching (108) the second graphene film to the first graphene film by adhesive and the layer of nanoparticles, forming (110) a laminated graphene film comprising a predetermined number of graphene film layers by repeating the steps of arranging a layer of nanoparticles and arranging an adhesive and attaching a graphene film, where the laminated graphene film is formed to have an anisotropic thermal conductivity. USE - Method of manufacturing a graphene based heat sink. ADVANTAGE - The method enables to vertically align graphene to increase the usability of thermal interface materials with high out-of-plane thermal conductivity. The heat sink has configurable properties and utilizes the very high in-plane thermal conductivity of a graphene film guide the heat in a direction away from the base plate which in use is placed in contact with the object to be cooled.
