| titleOfInvention | Digestion method of graphene material |
| abstract | The invention belongs to the technical field of graphite material analysis, and particularly relates to a digestion method of a graphene material. The digestion method comprises the following steps: (1) oxidation of graphene: oxidizing graphene to form graphene oxide; (2) modification treatment of graphene oxide: introducing amino groups into the graphene oxide conjugated region; (3) digestion treatment: mixing the modified graphene oxide and hydrofluoric acid, pressurizing to 0.20-0.32MPa at the temperature of 170-200 ℃, maintaining the pressure for 20-60min, then relieving the pressure to normal pressure, reacting for 10-60min at normal pressure, and performing pressurization and pressure relief circulation for 3-5 times, and discharging. Wherein, the pressure relief to normal pressure is as follows: and (5) releasing the pressure to the normal pressure within 10-30 s. The method can efficiently complete the digestion treatment of the graphene, and avoids the influence of the residue of the graphene on the accuracy of the test result. |
