WhatsApp: +86 18838072829In this study, we propose a novel method to exfoliate hexagonal boron nitride (hBN) powders to produce boron nitride nanosheets (BNNSs) by applying the synergistic exfoliation resulting from pure shear ball milling and ultrasonication. Pure shear ball milling is based on traditional ball milling, but uses a supplemental weight block as a vertical load on the milling balls.
