A method for the production of graphene by exfoliation of graphite, said method comprising: providing a mixture of graphite in a solvent (e.g. water), subjecting the mixture to sonication at at least one frequency in the range of 15 to 30 kHz, and subjecting the mixture to sonication at at least one frequency in the range of 50 to 250 kHz. The two sonications can be performed in two different reactors, with one at 85 degrees C and the other at 23 degrees C. |
