▎ 摘　　要

NOVELTY - Manufacture of graphene barrier film involves performing primary chemical vapor deposition process on a metal catalyst layer to form a graphene precursor layer, performing secondary chemical vapor deposition process on the graphene precursor layer such that graphene precursor layer is converted to a graphene layer, forming a polymer protective layer on the graphene layer, removing the metal catalyst layer from one side of the graphene layer, transferring the graphene layer to a target substrate. The graphene barrier film has thickness of 100 nm or less. USE - Manufacture of graphene barrier film used for electronic device and foodstuff packaging material. ADVANTAGE - The method enables efficient manufacture of graphene barrier film with excellent surface smoothness, water barrier property, and gas barrier property.
