▎ 摘 要
NOVELTY - Preparation of graphene thin film comprises preparing graphene oxide suspension, adding adhesive, incubating, coating on substrate, drying to obtain substrate graphene oxide composite film, high temperature annealing, and separating substrate and graphene thin film. USE - Method for preparing graphene thin film (claimed). ADVANTAGE - The method is simple, short, and suitable for industrial production and can prepare large-area graphene film.
