Preparation of graphene via wet ball milling and in situ ...

16-12-2019  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 (H 2 O–ethanol) without binder or surfactant.

Ball Milling - an overview ScienceDirect Topics

Ball milling is a way to exfoliate graphite using lateral force, as opposed to the Scotch Tape or sonication that mainly use normal force. Ball mills, like the three roll machine, are a common occurrence in industry, for the production of fine particles. During the ball milling process, there are two factors that contribute to the exfoliation.

Graphite Union Process

Graphite is difficult to grind into a fine particle size because of its often occurrence as flakes and the covalent bonds’ strength within the atom-thick sheets that make up graphite. However, two dry grinding Attritors designed and manufactured by Union Process, the SD Series and the HSA Series , as well as our wet grinding batch Attritor S Series , are well suited for grinding graphite.
