▎ 摘 要
NOVELTY - Preparing liquid phase ultrasonic peeling agent comprises adding graphite and stripping agent to the solvent, performing ultrasonic stripping to obtain a dispersion liquid, separating, purifying and drying dispersion liquid to obtain graphene, where the stripping agent is organic small molecule containing 2-5 carbon rings or carbon heterocycles and not all rings are on the same straight chain, the carbocyclic ring or carbocyclic heterocycle is a four-membered ring, a five-membered ring, a six-membered ring or a seven-membered ring, the stripping agent contains 0-10 halogen atoms, preferably 0-3 halogen atoms. USE - The peeling agent is useful for preparing graphene or graphene oxide (claimed). ADVANTAGE - The method is simple.
