▎ 摘　　要

NOVELTY - Graphitization of graphene heat conducting film comprises dissolving graphene powder and silicon carbide nanoparticles in anhydrous ethanol, stirring to obtain mixed solution, adding molecular modifier to mixed solution, refluxing and stirring, centrifuging, washing with ethanol and drying to obtain nanoparticles; dissolving 4'-diaminodiphenyl ether in organic polar solvent, introducing inert gas, stirring, adding 3,3,4,4-tetracarboxylic benzophenone anhydride and continuously stirring to obtain polyacrylic acid solution; and adding nanoparticles to polyacrylic acid solution, performing in-situ polymerization reaction to obtain polymerization solution, flatly spreading polymerization solution on substrate, heating to obtain composite film, stacking the composite film, carbonizing, sending carbonized raw material into high-frequency induction graphitizing furnace, performing heat preservation graphitization to obtain graphene film and mechanically rolling graphene thin film. USE - The method is for graphitization of graphene heat conducting film. ADVANTAGE - The film has improved flexibility and tensile strength. DESCRIPTION OF DRAWING(S) - The drawing shows a flow diagram of graphitization of graphene heat conducting film (Drawing includes non-English language text).
