The preparation of powders by ball milling usually results in particle refinement and increased specific surface area (Li et al., 2009; Gu et al., 2017). Inversely, the understanding of mechanical pulverization should not only be a simple mechanophysical process but a complex physicalchemical process (Gu et al., 2017; Wang et al., 2022). This ...

Ball milling is a mechanical technique that is broadly used to grind powders into fine particles [134141]. The reactants are generally broken apart using solvent molecules in the traditional method; but in ball milling, reactants are broken by using mechanical forces. The term mechanochemistry has been introduced very recently [142].

The results show that with the increase of ball milling times, the yield of sBN is %, %, % and %, respectively. It can be seen that the yield of sBN is on the rise with the increasing milling times. This indicates that as the ball milling time increases, the exfoliation efficiency BN is gradually higher.
