摘　　要：简单高效的制备高结晶度的六方氮化硼(h-BN)纳米片一直是一个挑战性的课题。本文提出了一种采用微波水热剥离制备高结晶度的h-BN纳米片的方法。通过XRD、SEM、TEM、AFM和拉曼等表征手段证明了该方法的有效性,并表征了剥离制备纳米片的特性。借助于表征分析结果,提出了微波水热剥离制备氮化硼纳米片的机制,为应用于制备其他的二维材料奠定了基础。The preparation of large hexagonal boron nitride(h-BN) nanosheets with high crystallinity has always been a challenging topic.In this paper,a method for preparing high crystallinity h-BN nanosheets exfoliated by microwave-assisted hydrothermal method is presented.By XRD,SEM,TEM,AFM,Raman and other characterization methods,the validity of the method was proved,and the properties of the nanosheets were characterized.Based on the results of characterization analysis,the mechanism of microwave hydrothermal method to prepare boron nitride nanosheets was proposed,which laid a foundation for the preparation of other two-dimensional materials.
