Influence of dry and wet ball milling on dispersion ...
2013-1-1 · Under dry conditions, only particles that directly filled the pots were observed, whereas under the wet conditions, particles mixed with water filled the pots. Accordingly, the wet grinding of the CNTs produced long fiber shapes. During the grinding process, the impact forces of the milling balls are different between the dry and wet conditions.

Influence of dry and wet ball milling on dispersion ...
Dry and wet ball milling approaches are compared on dispersibility of CNT nanofluid. Grinding is effective method for reducing the agglomerated particle size of CNTs. SDS molecule can exert an “unzippering force” to disperse CNTs in base fluid. Best dispersibility of nanofluid is obtained for purified and wet ground MWCNTs.
