▎ 摘 要
NOVELTY - Method for preparing graphene/graphene oxide composite material using graphene oxide assisted liquid phase stripped graphite involves (i) adding graphene oxide into a liquid medium or an organic solvent for ultrasonic treatment, further adding graphite and mixing to form a mixed solution (A), and ultrasonically stripping the mixed solution (A), and (ii) centrifuging the processed ultrasonically stripped mixture to remove the unpeeled graphite, and collecting the obtained suspension. USE - The method is useful for preparing graphene/graphene oxide composite material using graphene oxide assisted liquid phase stripped graphite for preparing supercapacitor (all claimed). ADVANTAGE - The method enables preparation of graphene/graphene oxide composite material with excellent dispersing effect on graphene, which prevents re-polymerization of the exfoliated graphene sheets, absorbs and conducts the heat generated during the ultrasonic stripping process by the liquid medium, and avoids overheating from cause defects in graphene/graphene oxide, by simple, non-toxic and economical process.
