▎ 摘　　要

NOVELTY - A graphene oxide high orientation pyrolysis graphite film is prepared by mixing graphene oxide and water, subjecting to ultrasonic dispersion, adding electric conduction polymer and high purity graphite, stirring, coating obtained solution on a substrate, pre-drying, curing, rolling, drying to obtain graphene thin film, subjecting to graphitization treatment under inert gas protection, and cooling naturally. USE - Method of preparing a graphene oxide high orientation pyrolysis graphite film. ADVANTAGE - The method is simple and low cost, and prepares film having uniformed thickness and good heat conducting function.
