▎ 摘　　要

NOVELTY - The method involves filling graphene oxide slurry in through-holes of an oxidized graphene film, where solid content of the graphene oxide slurry is about 5-8%. Drying operation, carbonization operation and graphitization operation of the graphene oxide slurry are performed to obtain a graphene heat conduction film with enhanced longitudinal heat conduction performance. Aperture of each through-hole is measured for about 0.01-5 mm, where direction of the through-hole is vertical to extension direction of the graphene heat conduction film. USE - Method for enhancing longitudinal heat conduction performance of a graphene heat conduction film (claimed). ADVANTAGE - The method enables improving longitudinal heat conduction performance of the graphene heat conduction film and strong operability.
