▎ 摘  要

NOVELTY - Preparation of graphene/cyanoethyl cellulose composite film involves dispersing graphene oxide in a dimethylformamide solution, ultrasonically-processing the formed dispersion liquid until graphene oxide is completely melted to obtain a graphene oxide solution, dissolving prepared cyanoethyl cellulose in dimethylformamide, slowly pouring the cellulose solution into the graphene oxide solution, stirring the mixed solution with a magnetic stirrer, forming a composite film, drying the composite film using a vacuum drying oven, reducing the composite film, selecting a fixed area of the composite film, and coating two sides of the fixed area of the composite film with a silver adhesive agent to form an electrode to test dielectric properties. USE - Preparation of graphene/cyanoethyl cellulose composite film used for forming electrode. ADVANTAGE - The graphene/cyanoethyl cellulose composite film enables formation of electrode having improved dielectric property.
