HEAT DISSIPATION FILM, AND METHOD AND APPARATUS FOR MANUFACTURING THE SAME

摘要

PROBLEM TO BE SOLVED: To provide an inexpensive heat dissipation film high in thermal conductivity and excellent in breaking fracture resistance.SOLUTION: The method for manufacturing a heat dissipation film having a heat transfer layer formed by uniformly dispersing graphene fine particles and carbon nanotubes comprises: (1) sandwiching a mixture layer having 0.05-0.2 of a ratio of the mass of the carbon nanotubes and 0.01-0.1 of a ratio of the mass of a binder resin to the total mass of the graphene fine particles and the carbon nanotubes by a pair of first plastic films to form a laminated film; (2) densifying the mixture layer by heat-pressing the laminated film; (3) burning the mixture layer exposed by peeling a first plastic film; (4) forming a heat transfer layer densified by pressing the obtained burned layer; and (5) covering the heat transfer layer with a second plastic film or an insulating resin.
