NOVELTY - A graphene composite thermal gasket comprises multilayer graphene foam film and adhesive arranged along thickness direction of the film. The multilayer graphene foam film is added in an amount of 50-95 wt.%. USE - Graphene composite thermal gasket. ADVANTAGE - The thermal conductive gasket has low density, high thermal conductivity in the thickness direction and low thermal resistance. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for preparation of the graphene composite thermal gasket, which involves stacking graphene foam film layer by layer into mold, applying pressure to make the film adhere tightly, coating adhesive glue on the obtained pressed graphene thermal conductive foam film to obtain a block, solidifying and forming, cutting into sheets along the stacking direction, dipping the cut sheet into dipping glue, taking out, hot pressing the taken out sheet, trimming the edges of the formed sheet, and removing the adhesive area on the edge.
