▎ 摘　　要

NOVELTY - The film (1) has a heat-transfer layer (11) provided with graphene micro particles and binder resin. A plastic film (12) is adhered to a surface of the heat-transfer layer. Mass ratio of the binder resin and the graphene micro particles in the heat-transfer layer is 0.001-0.1.The graphene micro particles of heat-transfer layer are arranged in the plastic film in parallel. Surface resistance of the heat-transfer layer is 5 ohms/square. Diameter of the graphene micro particles is 5-100 micro meters. Thickness of the plastic film is 20-100 micrometers. USE - Thermal radiation film for radiating heat produced from an electronic component e.g. microprocessor, image processing chip and memory in a small-sized electronic device e.g. notebook computer, smart phone and mobile telephone. ADVANTAGE - The graphene micro particles of heat-transfer layer are arranged in the plastic film in parallel, so that manufacturing cost of the radiation film is reduced and heat conductivity of the heat-transfer layer is improved. DETAILED DESCRIPTION - The binder resin is acrylic resin, polystyrene resin or polyvinyl alcohol. The acrylic resin is polymethyl acrylate, polymethylmethacrylate, polycarbonate, PVC or Acrylonitrile, Butadiene, and Styrene resin. INDEPENDENT CLAIMS are also included for the following: (1) a method for manufacturing a thermal radiation film (2) a manufacturing apparatus for a thermal radiation film. DESCRIPTION OF DRAWING(S) - The drawing shows a sectional view of a thermal radiation film. Thermal radiation film (1) Heat-transfer layer (11) Plastic film (12)
