When graphite powder is exposed to ultrasoniion in the presence of a suitable solvent, the powder fragments into nanosheets, which are stabilized against aggregation by the solvent. The enthalpy of mixing is minimized for solvents with surface energies close to that of graphene (∼68 mJ/m(2)). The exfoliated nanosheets are free of defects and oxides and can be produced in large quantities ...
· Preparation of GNs via ball milling. The ball milling of graphite was carried out in a planetary ballmilling machine with four 2500 ml stainless steel jars with dry ice at 150 rpm in the speed of revolution and 300 rpm in the speed of autorotation.
