▎ 摘　　要

NOVELTY - The utility model claims an electrode device and graphene film preparation system, comprising a supporting piece and a fixing piece, the supporting piece is set to be used for supporting the oxidation graphene film, the fixing piece is connected on the supporting piece, the supporting piece and the fixing piece is formed between the reducing space for fixing the oxidation-graphene film, The surface of at least one of the supporting piece and the fixing piece and the oxidation graphene film is surface contact The electrode device of the utility model replaces the point contact or wire contact as surface contact which greatly increases the electrode device and the contact graphene film, shortens the production period, further improves the production efficiency, after improving the production efficiency, shortening the time of soaking the reduced graphene film in the electrolyte solution, reducing the probability of swelling and structure damage of the graphene of the film, improving the quality of the graphene film. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a system for preparing a film graphene to any one of claims to.
