Removing Dry Ball Milling Media From Powder

How to Perform Dry Exfoliation on Graphene

Dry Ball Milling. Dry milling is another alternative to produce graphene. Graphite layers can be shifted by ball milling a mixture of graphite and chemically inert water-soluble inorganic salts. The ensuing water washing and sonication of the milling products can result in the production of graphene powders.
