▎ 摘　　要

NOVELTY - Preparing graphene heat-conducting film, comprises reducing the graphene oxide film by the method of flame firing, performing a first compaction treatment on the graphene oxide after the flame reduction treatment, and carrying out high temperature thermal reduction and a second compaction process. USE - Preparing graphene heat-conducting film used in mobile phone, computer and other electronic products. ADVANTAGE - The method enables reducing the graphene oxide film by using flame firing method, performing a first compacting process to graphene oxide after the flame reduction treatment, and carrying out high temperature thermal reduction, and performing a second compaction process, so that the film body is formed with capillary gas channel, thus avoiding the gas accumulated in the film, and effectively reducing the increase of the film thickness.
