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 graphene sheets (≤3 layers ...

Wet milling, also known as wet grinding, is a process through which particles that are suspended in a liquid slurry are dispersed in that liquid by shearing or crushing. Once the milling process is complete, these particles are ready for use or can be dried and separated for incorporation into additional products.
