Edge carboxylated graphene nanosheets via ball milling PNAS

Apr 10, 2012Low 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. The resultant ECG is highly dispersable in various solvents to self exfoliate into single and few layer ( 5 layers) GNs.

Low Cost Synthesis of Highly Luminescent Colloidal Lead

High energy ball milling is a type of mechanical grinding of materials. This process can be conducted in a dry (without solvents) or wet (with solvents) fashion. Laboratory scale ball milling (5100 mL scale) is a batch process, whereas industrial ball mills can be operated in a continuous mode, thus oering a very high synthesis throughput.
