▎ 摘　　要

NOVELTY - Preparation of graphene comprises ball milling graphite with organic solvent at 1 g/30-50 ml ratio using grinding steel ball or agate ball, performing centrifugal separation of graphite and organic solvent, retaining centrifugate, distilling and filtering to remove organic solvent. USE - Method for preparing graphene (claimed). ADVANTAGE - The method reduces production cost and reduces pollution. DESCRIPTION OF DRAWING(S) - The drawing shows a process flow diagram of graphene preparation (Drawing includes non-English language text).
