Ball Milling an overview ScienceDirect Topics

Milling of graphite layers can be instigated in two states: (i) dry ball milling (DBM) and (ii) wet ball milling (WBM). WBM process requires surfactant/solvent such as N,N Dimethylformamide (DMF) [22],N -methylpyrrolidone (NMP) [26],deionized (DI) water [27],potassium acetate [28],2-ethylhexanol ( E -H) [29] and kerosene (K) [29] etc. and is comparatively simpler as compared with DBM.
