Functionalized for energy applications

graphite milling (ECG) can be produced by solid state ball graphite powder in the presence of dry ice (solid phase of carbon dioxide, CO 2) (Figure 1a and b) [14]. Owing carboxylate to the large repulsive forces between the edge-groups, the resultant ECG can be efficiently exfoliated into a few-layer nanosheets in polar solvents (e.g. various
