▎ 摘　　要

NOVELTY - The preparation method involves coating a graphene oxide-dispersed solution on a substrate to form a graphene oxide thin film. The graphene oxide thin film is reduced using a chemical reduction method and a pressure-assisted thermal reduction method, respectively, to form a reduced graphene oxide film. The plastic substrate includes part selected from the group consisting of polyethersulfone, polyimide, polycarbonate, polyethylene naphthalate, and polyethylene terephthalate. USE - Preparation method of RGO film (claimed). Uses include but not limited to graphene electrode, organic thin film transistor, antistatic film (all claimed). ADVANTAGE - Maintains an excellent antistatic property even after a long period of time since antistatic film has a very low sheet resistance. Exhibits an excellent electrical property caused by a high carbon or oxygen composition ratio and a dense interlayer structure. DESCRIPTION OF DRAWING(S) - The drawing shows the schematic diagram illustrating a preparing method of RGO films.
