Exfoliation of graphite by dry ball milling with cellulose

Dry ball milling of graphite with cellulose and related polysaccharides was found effective for exfoliation-dispersion of graphene-like carbon. The exfoliation behavior was found to depend strongly on the polymer species; namely, polysaccharides are much more effective than thermoplastic polymers.

Mechanical Milling: a Top Down Approach for the Synthesis

Awasthi et al[98] reported the formation of carbon in different nanoparticle forms by ball-milling of graphitic carbon. Ball-milling of graphite was carried out in attritor ball mill at room temperature in hexane medium for different times i.e. 24, 48 and. The self-coagulated carbon agglomerates were obtained in the case of 24 and BMC samples.

Ball mill Wikipedia

A ball mill, a type of grinder, is a cylindrical device used in grinding (or mixing) materials like ores, chemicals, ceramic raw materials and mills rotate around a horizontal axis, partially filled with the material to be ground plus the grinding medium. Different materials are used as media, including ceramic balls, flint pebbles and stainless steel balls.
