USE - The method is useful for manufacturing a vertically aligned laminated graphene based thermally conductive film, where the film is useful in thermal interface material (claimed). ADVANTAGE - The method: provides the film, which exhibits improved in-plane thermal conductivity, hence provides high thermal transport both in the vertical direction as well as in a selected direction in the plane of the film; is capable of controlling the flexibility and tensile strength of the resulting thermally conductive film by controlling the ratio between adhesive and graphene film; and prevents crack formation and damage of film.
