NOVELTY - Graphene film, which is not calendered, and graphene film has airtight bubble structure.. USE - Used as graphene film. ADVANTAGE - The graphene film reinforced heat-conducting composite film can carry out specific requirements except the heat conducting requirement for different polymer environments, such as flexible application, absorbing/radiating application, mechanical enhancement. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are also included for: (1) A graphene film reinforced thermally conductive composite film comprising layers of graphene film and the graphene film has through the graphene film several through holes on the upper and lower surfaces of the through holes are filled with polymers. (2) A graphene film-enhanced thermally conductive flexible substrate comprising graphene film, graphene film having a structure that runs through the graphene film Several through holes on upper and lower surfaces of the device, through holes are filled with polymers, and the polymers comprises silicone rubber, silicone glue, epoxy resin, polyvinyl alcohol, polyurethane, polyvinyl butyral, and/or carboxymethyl celluloses. (3) A phase change material for enhancing endothermic graphene film, comprising one layer of the graphene film, graphene film having a structure that runs through the Several through holes on the upper and lower surfaces of the graphene film, the through holes are filled with a polymer, and the polymer is liquid paraffin. (4) A graphene film reinforced thermally conductive sealing material, comprising graphene film, graphene film has several through holes running through the upper and lower surfaces of the graphene film, through hole is filled with a polymer, and the polymer includes silicone rubber, silicone glue, epoxy resin, polyvinyl alcohol, polyurethane, polyvinyl butyral, and/or carboxymethyl cellulose.
