▎ 摘　　要

NOVELTY - High thermal conductive hybrid film comprises: many reduced graphene oxides; and many nano hybrid structures, where the nano hybrid structures are mixed with the reduced graphene oxides, and each of the nano hybrid structures comprises a nanodiamond and a carbon layer coating the nanodiamond. USE - Used as high thermal conductive hybrid film. ADVANTAGE - The film: improves the through-plane thermal conductivity of graphene; exhibits through-plane thermal conductivity of greater than or equal to 0.5 W/m.K; increases the interfacial bonding force between the nanodiamond and the graphene oxide; and is formed after the heating process can be shown the closed structure, at the same time, the carbon layer is formed by a carbonization of the polydopamine can be used as a bridge for the transmission of the phonons in a vertical direction to enhance the through-plane thermal conductivity of the high thermal conductive hybrid film, thus indicating that the through-plane thermal conductivity of the film can be improved effectively. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for manufacturing method of the film, comprising preparing a graphene oxide solution, where the graphene oxide solution comprises the graphene oxides, preparing a nano-particle solution, where the nano-particle solution comprises the nano initial hybrid structures, and each of the nano initial hybrid structures comprises a nanodiamond and a polydopamine layer coating the nanodiamond, providing a mixing process for mixing the graphene oxide solution and the nano-particle solution to obtain a mixing solution, providing a preliminary-film forming process for filtrating the mixing solution and then remaining a mixture of the graphene oxides and the nano initial hybrid structures to form a preliminary film, and providing a heating process for heating the preliminary-film to reduce the graphene oxides as many reduced graphene oxides and convert the polydopamine layers into many carbon layers, so as to convert the nano initial hybrid structures into many nano hybrid structures, where the high thermal conductive hybrid film is formed.
