NOVELTY - The method involves pouring the liquid in an agate tank at a certain temperature, maintaining the temperature, and shaking to uniform state. The planetary ball mill is connected to the agate tank, after a certain speed and a certain time. The liquid in the agate tank is mixed with de-ionized water after centrifuging. The freezing and drying of supernatant is carried out after a certain time to obtain graphene, in which the mass of graphite is 0.5-5 g, and the mol ratio of graphite to propanetriol is 1:2-7. USE - Method for wet preparation of graphene from glycerin as liquid phase in planetary ball mill path. ADVANTAGE - The process is carried out simply and at low cost, and the prepared graphene has low defect.
