▎ 摘 要
NOVELTY - Preparing graphene paper involves adding the graphite oxide into alcohol as solvent, performing under ultrasonic treatment to obtain graphene oxide suspension liquid and filtering by microporous film under vacuum condition to obtain graphene oxide film. The obtained graphene oxide film is placed into the tube furnace, heated under the protection of inert gas in reducing gas atmosphere to obtain the graphene paper. USE - Method for preparing graphene paper used as current collector (claimed), or a power source for making wearable devices or clothes, or a power source for making a conductive mask. ADVANTAGE - The method enables to prepare graphene paper which has excellent electrical conductivity.
