Functionalized graphene nanoplatelets from ball milling for energy .

Feb 4, 2016 . For example, edge-carboxylated graphite (ECG) can be produced by solid state ball milling graphite powder in the presence of dry ice (solid phase of carbon dioxide, CO2) (Figure 1a and b) [14]. Owing to the large repulsive forces between the edge- carboxylate groups, the resultant ECG can be efficiently.
