▎ 摘　　要

NOVELTY - Preparing graphene film comprises (a) pouring graphene oxide into 0.1-10 mg/ml of an aqueous solution and then covering on a paper substrate, drying and solidifying, (b) soaking a bearing paper with a graphene film layer in 0.5-2 mole/l of hydrochloric acid, phosphoric acid, acetic acid or sulfuric acid and then hydrolyzing and reacting to obtain graphene oxide film layer, and (c) taking out the graphene oxide film layer and then soaking in 45-55 mass% of hydroiodicacid and reacting. USE - The method is useful for preparing graphene film (claimed). ADVANTAGE - The method rapidly prepares the graphene film with large specific surface area in a convenient manner.
