Edge-carboxylated graphene nanosheets via ball milling

Abstract. 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.

Grinding Down to the Nanoscale with Planetary Ball Mills

Planetary ball mills are the most commonly used ball mills in laboratories for preparing samples ranging from soft to hard to brittle and fibrous materials. The mill derives its name from the unique kinematics wherein the grinding bowls are mounted on a rotating "sun" disk that rotate in the opposite direction around the disk centre.
