2020-11-1  Wet ball milling was found to not only be efficient directly exfoliate the graphite into GNSs, especially in the presence of nanoparticles, but also in uniformly dispersing GNSs in zirconia powder. Under the cushioning effect of the ball-milling solvent, the prolonged ball milling process did not cause serious damage to the GNSs.

2012-4-10  Low-cost, high-yield production of graphene nanosheets (GNs) is essential for practical applications. We have achieved high yield of edge-selectively carboxylated graphite (ECG) by a simple ball milling of pristine graphite in the presence of dry ice. The resultant ECG is highly dispersable in various solvents to self-exfoliate into single- and few-layer (≤ 5 layers) GNs.
