NOVELTY - Digestion method of graphene material involves (1) oxidizing graphene to form graphene oxide, (2) introducing amino groups into the conjugated region of graphene oxide, (3) pressurizing to a pressure of 0.20-0.32MPa, after mixing the modified graphene oxide and hydrofluoric acid at a temperature of 170-200degreesC, releasing the pressure to normal after maintaining the pressure for 20-60 minutes, reacting under normal pressure for 10-60 minutes, and decompressing 3-5 times of pressure release and discharge. USE - Digestion method of graphene material. ADVANTAGE - The method can efficiently complete the digestion treatment of the graphene and avoid the residual of the graphene from affecting the accuracy of the test result.
