▎ 摘　　要

NOVELTY - Preparing thermal conductive composite film comprises (i) graphitizing carbon nano-tube to obtain the carbon nano-tube after processing, (ii) processing the carbon nano-tube into fatty acid, mixing with the graphene, and drying to obtain the carbon nano tube-graphene mixture, (iii) ball milling the carbon nano tube-graphene, mixing with dispersant and solvent, grinding to obtain the dispersion of carbon nano tube-graphene, (iv) mixing aramid chopped fiber and the lyophobic agent and water for lyophobic treatment to obtain aramid chopped fiber slurry, mixing the aramid fiber and water and pulping to obtain aramid fiber pulp, (v) mixing the aramid chopped fiber slurry and the aramid precipitated fiber slurry to obtain the fiber slurry, (vi) mixing the dispersion of carbon nano tube-graphene and fiber slurry to obtain the mixed slurry, and (vii) diluting the mixed slurry, sizing to the paper forming machine, filtering, drying, rolling and forming. USE - Preparing thermal conductive composite film. ADVANTAGE - The method enables to prepare thermal conductive composite film that has high efficiency, acid resistance, alkali resistance, high temperature resistance and high strength characteristics, and has improved radiating effect in XYZ three directions. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are included for: (1) a thermally conductive composite film; and (2) a radiating element.
