Abstract
Method of manufacturing a vertically aligned laminated graphene based thermally conductive film. The method comprising: attaching first and second graphene film using a layer of nanoparticles and an adhesive; forming a layered film comprising a predetermined number of graphene film layers by repeating the steps of arranging a layer of nanoparticles, arranging an adhesive and attaching a graphene film; and laminating the layered film by applying pressure and heat to cure the adhesive, thereby forming a laminate film; cutting the laminate film at an angle in relation to a surface plane of the film to form the vertically aligned laminated graphene based thermally conductive film.
Claims11
A vertically aligned laminated graphene based thermally conductive film comprising:
- a plurality of layers of graphene film reaching from a bottom surface to a top surface of the thermally conductive film, each layer of graphene film comprising a layer of nanoparticles arranged on the graphene film and each layer of graphene film being separated from an adjacent layer of graphene film by an adhesive layer arranged on the layer of nanoparticles, the nanoparticles being configured to improve an adhesion strength between adjacent graphene films, and
- wherein each layer of graphene film is tilted with respect to a surface plane of the thermally conductive film.
