机械裂解法是最早生产石墨烯的方法，至今仍在实验室中广泛使用。然而，这种方法的一个关键问题是产率极低。我们定制了球磨条件，以产生温和的剪切力，以高产量和高效率生产高质量的氮化硼(BN)纳米薄片。近边X射线吸收精细结构测量表明，BN纳米片的面内结构没有受到破坏。苯甲酸苄酯作为研磨剂，减少了球击和研磨污染。该方法适用于制备纳米片材的任何层状材料。
Mechanical cleavage by Scotch tape was the first method to produce graphene and is still widely used in laboratories. However, a critical problem of this method is the extremely low yield. We have tailored ball milling conditions to produce gentle shear forces that produce high quality boron nitride (BN) nanosheets in high yield and efficiency. The in-plane structure of the BN nanosheets has not been damaged as shown by near edge X-ray absorption fine structure measurements. The benzyl benzoate acts as the milling agent to reduce the ball impacts and milling contamination. This method is applicable to any layered materials for producing nanosheets.
