Abstract: The present disclosure provides a light-weight flexible high-thermal-conductivity nano-carbon composite film and a method for preparing same. The nano-carbon composite film includes a plurality of composite units laminated sequentially. The composite unit includes flexible adhesive layers and a graphene film layer, and the flexible adhesive layers are disposed on both sides of the graphene film layer. The preparation method includes sequentially laminating the composite units and hot pressing to obtain the nano-carbon composite film. The nano-carbon composite film has the characteristics of high thermal conductivity, light weight and flexibility, and has an in-plane thermal conductivity of up to 500 W/m·K or higher, a density of 2.0 g/cm3 or less, and still a thermal conductivity of 500 W/m·K or higher after the nano-carbon composite film is repeatedly bent by 180° for 50 times while there is no peeling of graphene from the surface.
