Wet ball milling was used to exfoliate graphite platelets into graphenes in a liquid medium. Multi-layered graphite nanosheets with a thickness of 30 to 80 nm were dispersed into N,N-dimethylformamide (DMF) and exfoliated by shear-force-dominated ball milling carried out in a planetary mill. After high-speed centrifugation, irregular shaped single- and few-layer graphene sheets (≤3 layers ...

Fig. 1 shows the changes in the measured BET surface area with milling time for natural graphite milled in a planetary mill in various atmospheres. The specific surface area of samples milled in an inert atmosphere increased rapidly, from 6 m 2 /g to above 150 m 2 /g within 3 h of milling. However, this increase subsides after 10 h of milling as agglomeration sets in.
