Title: METHOD FOR MANUFACTURING A GRAPHENE BASED THERMALLY CONDUCTIVE FILM
Abstract:
There is provided a method for manufacturing a graphene based film, GBF. The method comprises: providing graphene oxide sheets in an aqueous suspension; providing a substrate; providing the suspension on the substrate; heating the suspension on the substrate to form a graphene based film by means of self assembly; detaching the graphene based film from the substrate; performing thermal annealing of the graphene based film at a temperature in the range of 2800-3300°C in an inert ambient; and pressing the graphene based film at a pressure in the range of 50-300 MPa.
