Apr 10, 2012Results and Discussion. In a typical experiment, ball milling was carried out in a planetary ball-mill machine (Pulverisette 6, Fritsch; Fig. S1A) in the presence of graphite (5.0 g, Fig. 1A), dry ice (100 g, Fig. 1B) and stainless steel balls (Fig. S1B).Detailed experimental conditions for the ball milling can be found in the Materials and Methods section and Supporting Information.

Since the ball milling method is currently the most promising method for producing graphene on a large scale. the ball milling process is optimized in this paper, and a grinding disc structure ball mill is proposed. The ball mill effectively avoids the impact force between the grinding balls, protects the graphite lattice from being broken, and
