Layered structure transformations and exfoliation of h-BN during thermal cycling

Understanding structural transformation of hexagonal boron nitride (h-BN) at elevated temperatures is critical to obtain 2D-h-BN through thermal exfoliation. Therefore, in situ x-ray diffraction data are collected from h-BN powders while subjecting them a cycle. The potential define the structure order during temperature variations revealed by using an index (I 3D ). It was that no direct correlation with degree exfoliation layered and change appeared cycling. Furthermore, particle size dependence under also mapped.
