▎ 摘　　要

NOVELTY - The method involves coating graphene oxide slurry to obtain graphene oxide film. A graphene oxide element is subjected to pore-forming processing and toughening processing operations. Winding operation is performed to obtain porous oxide film coiled material. Pore size of the porous oxide element is determined for about 80-300 millimeter. The porous graphene oxide material is located into a graphite cylinder. High-temperature heat processing operation is performed. Porous oxide material rolling process is performed after performing high-temperature heat processing operation to obtain a graphene heat conducting film. USE - Graphene heat conducting film manufacturing method. ADVANTAGE - The method enables increasing excellent mechanical strength to avoid pre-treatment operation of low temperature section, so that material integrity can be ensured, thus reducing energy consumption of graphene heat conducting film production process, and hence improving production efficiency and avoiding material influence, cracking or burning defects of current preparation operation. DESCRIPTION OF DRAWING(S) - The drawing shows a schematic diagram of a graphene heat conducting film.
