Preparation of graphene by exfoliation of graphite using ...

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.

The ball mill was rotated at a rotational speed of 200 rpm. It was observed that at the rotational speed of 200 rpm; the shear forces acting over the graphene nanosheets are highest when the balls ...

Edge-carboxylated graphene nanosheets via ball milling

2012-04-10· Low-cost, high-yield production of graphene nanosheets (GNs) is essential for practical applications. We have achieved high yield of edge-selectively carboxylated graphite (ECG) by a simple ball milling of pristine graphite in the presence of dry ice.
