dry ball milling technique

Ball millingof graphite with appropriate stabilizers is another mode of exfoliation in liquid phase. 21 Graphite is ground under high sheer rates with millimeter-sized metalballscausing exfoliation to graphene (Fig. 2.5), under wet ordryconditions.For instance, this method can be employed to produce nearly 50 g of graphene in the absence of any oxidant. 22 Graphite (50 g) was ground in ...
