▎ 摘　　要

NOVELTY - The method involves filtering (S1) concentration of 0.25 mg/ml oxidized graphene suspension, and drying the suspension to obtain a graphene oxide film. The graphene oxide film is provided (S2) in metal precursor solution. A graphene oxide/metal precursor thin film is obtained. The precursor film is provided (S3) in a reactor at 15 to 200 degrees centigrade for a vacuum heating reduction reaction for 2 hours. A temperature is raised to 50 to l00 degrees centigrade. A reaction is continuously reduced for 0.5 to 2 hours to obtain the graphene/metal thin film as a base material of a composite. USE - Fluid preparation method for a composite current collector (claimed) for a super capacitor. ADVANTAGE - The method improves a super capacitor energy density of the composite current collector. DETAILED DESCRIPTION - The reactor is a tubular furnace. An INDEPENDENT CLAIM is also included for a composite current collector. DESCRIPTION OF DRAWING(S) - The drawing shows a flow diagram illustrating a fluid preparation method for a composite current collector.'(Drawing includes non-English language text)' Step for filtering a concentration of 0.25 mg/ml oxidized graphene suspension, and drying the suspension to obtain a graphene oxide film (S1) Step for providing a graphene oxide film in metal precursor solution (S2) Step for providing a graphene oxide/metal precursor thin film in a reactor (S3)
