AFM in Fig. 2 shows similar results, and the size of graphene sheets after ball milling was significantly reduced compared to graphene powder, with thickness decreases from 35 to 15 nm. In the process of ball milling, the continuous grinding of zirconia balls crushes graphene sheets, resulting in further exfoliation and rupture.
