▎ 摘  要

NOVELTY - Preparing graphene with ultrasonic, supercritical carbon dioxide and microwave stripping comprises carrying out three times stripping of graphite, where three stripping steps are in order i.e. ultrasonic first stripping, supercritical carbon dioxide secondary stripping and microwave stripping to obtain graphene layer i.e. with ten layers and graphene is free of organic functional group. USE - The method is useful for preparing graphene with ultrasonic, supercritical carbon dioxide and microwave stripping (claimed). ADVANTAGE - The method is simple, produces high quality with small structural defect product and suitable for large-scale production.
