WebThe structure of the prepared epoxy resin and vinyl ester resin is confirmed by FT-IR. Furthermore, the structure of VER is also confirmed by NMR techniques. The FT-IR spectrum of epoxy resin is shown in fig.1 (a). The 910 cm-1 absorption band in epoxy resin is due to oxirane ring and the absorption band near 1456 cm-1, WebFTIR spectroscopy of boron nitride provides us with the crucial insight into the morphology differences of the h-BN and BNNT allotropes, needed to properly quantify h-BN content in BNNT samples. Graphene-like BN nanomaterials, with a hexagonal BN network, present characteristic structural vibrations in the low-frequency region of an FTIR spectra.
