▎ 摘  要

NOVELTY - A graphene roll-to-roll coating apparatus (700), comprises: a first roller (250) that supplies a metallic member in a roll-to-roll manner; a pre-treating unit (400) that performs a surface treatment on the metallic member supplied through the first roller; a graphene forming unit (500) that forms and simultaneously coats graphene on a surface of the pretreated metallic member; and a second roller that collects the metallic member coated with the graphene in a roll-to-roll mechanism after the metallic member passes through the graphene forming unit. USE - The graphene roll-to-roll coating apparatus and method are useful for graphene roll-to-roll coating, and for coating a metallic member (claimed). ADVANTAGE - The graphene roll-to-roll coating apparatus efficiently manufactures a heat pipe having high heat transfer efficiency and high reliability with low cost by processing a surface of a metallic member such as a metallic pipe or a metallic plate to use it as a heat pipe or a heat plate. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are: (1) a graphene roll-to-roll coating method using a graphene roll-to-roll coating apparatus, comprising: supplying a metallic member from a first roller to a pre-treating unit in a roll-to-roll manner; performing a surface treatment on the metallic member supplied through the first roller in the pre-treating unit; transferring the metallic member into the graphene forming unit to form and simultaneously to coat graphene on a surface of the pre-treated metallic member; and collecting the metallic member coated with the graphene by a second roller in a roll-to-roll manner after the metallic member passes through the graphene forming unit; and (2) a metallic member coated with graphene, formed by the graphene roll-to-roll coating method. DESCRIPTION OF DRAWING(S) - The drawing shows a cross-sectional view of a graphene roll-to-roll coating apparatus.
