Preparation method of graphene composite heat-conducting film
The invention provides a preparation method of a graphene composite heat-conducting film, and relates to the technical field of heat-conducting film preparation. The preparation method of the graphene composite heat-conducting film comprises the following steps: S1, dissolving graphene oxide powder in deionized water to obtain a graphene oxide solution; s2, adding a proper amount of carbon fibers into the graphene oxide solution obtained in the S1, and mechanically and uniformly mixing to obtain a mixed solution of the graphene oxide and the carbon fibers; and S3, spraying the mixed solution obtained in the step S2 on a PET film, putting the PET film into a drying oven for drying, and then reducing to obtain the first-order graphene composite heat-conducting film. By adding the heat-conducting net, the carbon paper and the carbon cloth, the overall density of the composite heat-conducting film is increased, the overall toughness and strength are improved, meanwhile, the heat conductivity is improved, the overall stability is improved, and the composite heat-conducting film is ideal to use.
