▎ 摘　　要

NOVELTY - Graphene is transferred by forming chemical vapor deposition (CVD)-grown graphene on copper; transferring CVD-grown graphene from copper substrate to target substrate by (i) depositing thin film on CVD-grown graphene to form thin film-graphene and (ii) binding thin film-graphene onto target substrate; and delaminating thin film-graphene from copper substrate using hydrogen bubble method, in which the target substrate is a flexible polymer substrate. USE - Transferring graphene for graphene based flexible electronics application. ADVANTAGE - The method is direct and reliable and reuses copper to grow graphene until it reaches a critical thickness to grow graphene, thus reducing the price of industrial scale monolayer graphene. The material used for thin film formation is flexible enough and is a good transfer agent to transfer graphene onto different flexible polymer substrates. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for graphene film obtained by transferring method of graphene. DESCRIPTION OF DRAWING(S) - The drawing shows a schematic diagram of a coating method in which thin layer of EVA is deposited onto graphene grown on copper (a) by spray coating and (b) by spin coating.
