    摘要:

    簡單高效的制備高結晶度的六方氮化硼（h-BN）納米片一直是一個挑戰(zhàn)性的課題。本文提出了一種采用微波水熱剝離制備高結晶度的h-BN納米片的方法。通過XRD、SEM、TEM、AFM和拉曼等表征手段證明了該方法的有效性，并表征了剝離制備納米片的特性。借助于表征分析結果，提出了微波水熱剝離制備氮化硼納米片的機制，為應用于制備其他的二維材料奠定了基礎。

    Abstract:

    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 nanoparticles by microwave-assisted hydrothermal is presented. By means of 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 to prepare boron nitride nanosheets was proposed, which laid a foundation for the preparation of other two-dimensional materials.
