The results show that with the increase of ball milling times, the yield of s-BN is 2.51%, 3.2%, 6.89% and 14.88%, respectively. It can be seen that the yield of s-BN 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.
