Boron Nitride Nanomaterials: Current Status of Developments and Applications
Hexagonal boron nitride (h-BN) is a layered material with a graphite-like structure in which planar networks of BN hexagons are regularly stacked. As the structural analogue of a carbon nanotube (CNT), BN nanotube (BNNT) was firstly predicted in 1994, since then, it has become one of the most intriguing non-carbon nanotubes. Compared with metallic or semiconducting CNTs, a BNNT is an electrical insulator with a bandgap of ca. 5 eV, basically independent of tube geometry. In addition, BNNTs possess high chemical stability, excellent mechanical properties and one of the highest thermal conductivities among of materials on Earth. The same advantages are applicable to a graphene analogue - a monoatomic layer of a hexagonal BN. Such unique properties make BN nanotubes, nanosheets and various types of nanoparticles a promising nanomaterial in a variety of potential fields such as optoelectronic nanodevices, waveguides, functional polymer and light metal matrix, and ceramic composites, hydrogen accumulators, water cleaners, electrically insulating substrates perfectly matching the CNT and graphene lattices.
