▎ 摘　　要

NOVELTY - The composite film includes graphene oxide added with graphene oxide dispersion liquid. The raw material for graphite alkenyl composite film includes 40 to 70 percent of solid raw material, 30 to 60 percent of stabilizing agent, 1 to 3 percent of surfactant and 1 to 10 percent of reinforcing agent. The mass ratio of the solid raw material and the liquid dispersant is 1 to 10: 100. The graphite alkenyl composite film is 10-50 microns thick and has a controllable heat conducting coefficient of 800-1600 watts m-1k-1 at room temperature. The tensile strength is 10-30 megaPascal and allows 180 degree bending without breakage. USE - Graphene oxide containing high thermal conductive graphite alkenyl composite film used in heat dissipation unit for electronic device. ADVANTAGE - The preparation method for high thermal conductive graphite alkenyl composite film allows simple low pressure and low process temperature operation which has small energy consumption and is low cost. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for a preparation method for high thermal conductive graphite alkenyl composite film.
