Abstract：The selection principle of the graphite stripping system,the graphene stripping systems including the organic solvent system,the aqueous surfactant system and the ionic liquid system,and the stripping equipments such as the ball mill,the high pressure jet machine,the ultrasonic generator,the high speed mixing shear,the supercritical device and the high-gravity rotating bed were reviewed.It is considered that the method of liquid-phase exfoliation is the most promising preparation method because of its low cost,simplicity,high yield and latent industrial expansibility.There are many shortcomings,such as low concentration,the polydispersity of layer and size,expensive or high boil of stripping medium,difficult separation of auxiliary agent.The major challenge in preparing graphene is the selection and design of suitable stripping system and equipment.
