Wet ball milling was used to exfoliate graphite platelets into graphenes in a liquid medium. Multilayered graphite nanosheets with a thickness of 30 to 80 nm were dispersed into N,Ndimethylformamide (DMF) and exfoliated by shearforcedominated ball milling carried out in a planetary mill. After highspeed centrifugation, irregular shaped single and fewlayer .
