Vibroelectronic Properties of Functionalized Single-Walled Carbon Nanotubes and Double-Walled Boron Nitride Nanotubes

Solvent-Free Functionalized Boron Nitride Nanotubes via Open-Air Cold Plasma for Highly Stable Dispersion in Water

“…One-dimensional nanomaterials, such as carbon nanotubes (CNTs) and boron nitride nanotubes (BNNTs), have many potential applications because of their unique properties. − In particular, BNNTs have an analogous structure to CNTs with a hexagonal honeycomb lattice that forms tubular structures but contains alternating B and N atoms, which give rise to their unique properties. , For example, because of the relatively strong electronegativity of N compared with that of B, the electrons within these p orbital bonds are localized toward the N nuclei instead of being delocalized in CNTs. , Therefore, BNNTs exhibit good electrical insulation properties (i.e., large band gaps of approximately 5.5 eV). − In addition, BNNTs exhibit excellent mechanical and thermal properties owing to their sp 2 hybridized bonds. − Therefore, they are highly resistant to oxidation, corrosion, and degradation even at high temperatures and in harsh chemical environments, making them ideal for various applications, including nanoelectronics, sensors, and reinforcement materials . Moreover, owing to their exceptional strength and modulus, − as well as their excellent neutron radiation absorption capabilities in harsh space environments, , there is growing interest in incorporating BNNTs into polymer matrix composites and nanocomposites to enhance their physical properties under extreme conditions such as high temperatures and oxidative atmospheres.…”
