▎ 摘　　要

NOVELTY - Preparing graphene radiating fin comprises (a) mixing a graphene slurry, aqueous resin and dispersant to obtain mixed slurry, (b) injecting the mixed slurry into a storage groove, flowing out from the storage groove to a moving drying channel, performing the operations of scraping and rolling in turn to obtain a prefabricated graphene radiating fin a thickness of 300-1200 mu m, and (c) cutting the prefabricated graphene radiating fin into equal parts to obtain graphene radiating fin with a thickness of 100-400 mu m. USE - The method is useful for preparing graphene radiating fin. ADVANTAGE - The method consumes less energy, and the obtained graphene radiating fin has high thermal conductivity and greatly reduced thickness of more than 50 mu m, so that it has excellent flexibility and heat dissipation, which is conducive to large-scale output. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for graphene radiating fin prepared by the above-mentioned method.
