Ball Milling an overview ScienceDirect Topics

Ball milling of graphite with appropriate stabilizers is another mode of exfoliation in liquid phase. 21 Graphite is ground under high sheer rates with millimeter-sized metal balls causing exfoliation to graphene (Fig. 2.5), under wet or dry conditions.For instance, this method can be employed to produce nearly 50 g of graphene in the absence of any oxidant. 22 Graphite (50 g) was

Preparation of graphene via wet ball milling and in situ

Functionalized graphene (G-MA) was prepared by a facile wet ball milling strategy, which achieved exfoliation and functionalization of graphite simultaneously. The G-MA showed excellent dispersion in water and polar solvents. Thus, a G-MA coating was prepared from G-MA in mixed solvents (H2O–ethanol) without

Exfoliation of Graphite with Triazine Derivatives under

A ball-milling treatment can be employed to exfoliate graphite through interactions with commercially available melamine under solid conditions. This procedure allows the fast production of relatively large quantities of material with a low presence of defects. The milling treatment can be modulated in order to achieve graphene flakes with different sizes.
