Exfoliation of graphite by dry ball milling with cellulose ...

2014-4-30  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. The compression-molded slabs from co-milled powder with cellulose
