Overall morphological characterization and XRD analysis of the precursor and exfoliated products. (a) SEM image of the precursor bulk BN, an inset of a photograph showing the precursor dispersed in IPA. (b, c) SEM images of exfoliated products, an inset in b of a photograph showing the exfoliated products dispersed in IPA standing for two weeks. (d) XRD patterns of the bulk BN (I) and exfoliated products (II), respectively, referring to the JCPDS file of the standard BN powders, an inset showing the amplified patterns.
