ball milling 2013

In this paper, a simple, cost effective, and scalable process for production of fewlayer graphene is reported by combining ball milling with exfoliants. The graphene was derived from lowcost graphite, which was subjected to highenergy ball milling in an aqueous medium containing a strong exfoliant (1pyrenecarboxylic acid) and a common solvent methanol.
