Xylitol-assisted ball milling of graphite to prepare long ...
A simple and effective xylitol-assisted mechanochemical stripping method has been used to peel graphite into graphene nanosheets (GNSs). Using xylitol as a ball milling aid can increase the shear force in the ball milling process and well get over the Van der Waals interlayer force between adjacent graphite layers. The prepared graphene has large …

Ball-milling of graphite and muilti-wall carbon nanotubes
The ball milling parameters were also examined: milling atmospheres, milling methods, milling mode and the addition of additive materials. In some experiments, hard materials such as alumina or silica were added to graphite and MWCNTs as additives to see whether graphite and MWCTs were shortened by ball-milling.

Low-cost, high-yield production of graphene nanosheets (GNs) is essential for practical applications. We have achieved high yield of edge-selectively carboxylated graphite (ECG) by a simple ball milling of pristine graphite in the presence of dry ice. The resultant ECG is highly dispersable in various solvents to self-exfoliate into single- and few-layer (≤ 5 layers) …

Ball-milling of graphite and muilti-wall carbon nanotubes
The ball-milling of graphite and MWCNTs with liquid additives reduced the agglomeration of MWCNT and transformed graphite to graphenes. The ball-milling of MWCNTs under impact mode usually resulted in the formation of an amorphous phase, whereas that under friction mode induced the fattening of nanotubes.
