▎ 摘  要

NOVELTY - Preparing graphene comprises (1) using 3% hydrogen peroxide and cyclohexane as intercalation agent; (2) using plasma device to excite the intercalation graphite for certain period of time under protection of argon or other inert gas to obtain aggregate of expanded graphite and graphene; and (3) mixing the aggregates with deionized water, adjusting pH to neutral, ultrasonically dispersing for period of time, and drying to obtain graphene. USE - The method is useful for preparing graphene. ADVANTAGE - The method: is environmentally-friendly.
