▎ 摘　　要

NOVELTY - High thermal conductivity of nano-carbon material comprises aggregates formed by aggregation of multiple carbon nanotubes and graphene. A surface of carbon nanotubes bonded to the aggregate. In the binding of the graphene to carbon nano-tubes the part of the carbon atoms on the carbon nano-tubes are connected to the carbon atoms on the graphene to form a sp3 bond. USE - Used as high thermal conductivity of nano-carbon material (claimed). ADVANTAGE - The material has high flexibility, high conductivity and excellent mechanical property. The method is simple, controllable and consumes less energy. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for preparing high thermal conductivity of nano-carbon material, comprising (i) providing an enriched graphene solution; (ii) fusing continuously and uniformly the graphene oxide solution into the surface of the carbon nanotube continuum to obtain a carbon nanotube/graphene composite membrane precursor; (iii) placing the carbon nanotube/graphene membrane precursor in a reducing atmosphere, heating at 200-500 degrees C for 15-120 minutes and heating to room temperature; and (iv) placing the carbon nanotube/graphene film in a protective atmosphere, heating at 1500-3000 degrees C for 15-360 minutes.
