Due to the strong in-plane but weak out-of-plane bonding, it is relatively easy separate nanosheets of two-dimensional (2D) materials from their respective bulk crystals. This exfoliation 2D can yield large nanosheets, hundreds micrometers wide, that be as thin one or a few atomic layers thick. However, underlying physical mechanisms unique each technique produce wide distribution defects, yields, functionalization, lateral sizes, and thicknesses, which appropriate for specific end applications. The five most commonly used techniques include micromechanical cleavage, ultrasonication, shear exfoliation, ball milling, electrochemical exfoliation. In this review, we present an overview field material with emphasis on progress over last decade. beneficial characteristics shortcomings process are discussed in context functional properties guide selection best given application. Furthermore, analysis standard applications exfoliated presented including use energy storage, electronics, lubrication, composite, structural By providing detailed insight into along advantages disadvantages technique, review intends reader toward batch-scale variety industrial
