▎ 摘 要
NOVELTY - Preparation of graphene comprises dissolving chloride intercalated graphite in deionized water while stirring to obtain 5-10 g/L chloride intercalated graphite suspension; and magnetically centrifuging at 0.01 Tesla and at 1000-5000 revolutions/minute to carry out peeling off intercalated graphite, collecting upper solution, pouring into filter funnel to carry out filtration, collecting residue, and drying. USE - Method for preparation of graphene (claimed). ADVANTAGE - The method has high yield and obtains graphene with excellent conductivity.
