We additionally mixed samples with added sulfur and iodine using high-energy ball milling for 0.5–1 h. We ground samples in a mortar and pestle to remove large agglomerations after ball milling, and then added DMF (if used). For each experiment, we loaded the mixture into a 10 mm-diameter, hardened-steel die, working in the glovebox.

A one-step method which involves exfoliating graphite materials (GIMs) off into graphene materials (GEMs) in aqueous suspension of CL-20 and forming CL-20/graphene materials (CL-20/GEMs) composites by using ball milling is presented. The conversion of mixtures to composite form was monitored by scanning electron microscopy (SEM) and powder X-ray diffraction (XRD).
The mixed powders of 1 mol Cu and 1 mol S were ball-milled at 425 rpm for different time (0.5–2 h) in a mixture atmosphere of high-purity argon (95%) and hydrogen (5%) gases using a planetary ball mill (QM-1SP2, Nanjing University, China). Stainless steel vessels and balls were used, and the weight ratio of the ball to powder was kept at 20:1.
