The prominence of two-dimensional hexagonal boron nitride (2D h-BN) nanomaterials in the energy industry has recently grown rapidly due to their broad applications in newly developed energy systems. This was necessitated as a response to the demand for mechanically and chemically stable platforms with superior thermal conductivity for incorporation in next-generation energy devices. Conventionally, the electrical insulation and surface inertness of 2D h-BN limited their large integration in the energy industry. However, progress on surface modification, doping, tailoring the edge chemistry, and hybridization with other nanomaterials paved the way to go beyond those conventional characteristics. The current application range, from various energy conversion methods (e.g., thermoelectrics) to energy storage (e.g., batteries), demonstrates the versatility of 2D h-BN nanomaterials for the future energy industry. In this review, the most recent research breakthroughs on 2D h-BN nanomaterials used in energy-based applications are discussed, and future opportunities and challenges are assessed.

“…In today's nanoscience and technology, SWC-NTs have been found to be used as sensors, LED devices, and photovoltaic and thermal reservoirs [6]. A review of the literature revealed some studies on the large armchair of SWCNTs such as (7,7), (8,8), (10,10), and (12,12) SWCNTs. Some research was also conducted on the ultra-small SWCNTs, such as (3,3) and (4, 4) SWCNTs.…”

“…BNNTs show remarkable resistance to oxidation and greater thermal stability; such remarkable features make them excellent candidates in mechanical reinforcement, radiation shielding, transparent bulk composites, etc. [10]. However, both CNTs and BNNTs have some common properties [7], such as high strength, high stiffness, high thermal conductivity, low density, and high length to diameter [7].…”

In this study, the optical refractive constants of the (5, 5) SWBNNT and (5, 5) SWCNT systems were calculated in both parallel and perpendicular directions of the tube axis by using Quantum ESPRESSO and YAMBO code. It also extended the optical behaviors of (5, 5) SWCNT and (5, 5) SWBNNT to both perpendicular and parallel directions instead of the parallel directions reported in the literature. It also looked at the effects of the diameter of the nanotube on the optical properties instead of chiral angles. From our results, the best optical reflection was found for (5, 5) SWBNNT, while the best optical refraction was found with (5, 5) SWCNT. It was observed that the SWCNT demonstrates refraction in both parallel and perpendicular directions, while (5, 5) SWBNNT shows perfect absorption in perpendicular direction. These new features that appeared for both nanotubes in perpendicular directions were due to new optical band gaps, which appear in the perpendicular directions to both nanotubes’ axis. The electron energy loss (EEL) spectrum of SWBNNT revealed the prominent π- and π + δ- Plasmon peaks, which demonstrates themselves in the reflectivity spectrum. Furthermore, little effect of diameter was observed for the perpendicular direction to both nanotubes’ axis; as such, the combined properties of (5, 5) SWBNNT and (5, 5) SWCNT materials/systems for transmitting light offer great potential for applications in mobile phone touch screens and mobile network antennas. In addition, the studies of optical properties in the perpendicular axis will help bring ultra-small nanotubes such as SWCNT and SWBNNT to the applications of next-generation nanotechnology.

“…However, due to the substitution of boron atoms in BNNTs in contrary to carbon atoms in CNTs, BNNTs offer unique physical and chemical properties significantly different from those of CNTs . The distinctive properties of BNNTs due to the presence of boron atoms in their structural configuration include noncytotoxicity, optical transparency, exceptional electronic insulation, excellent thermal conduction, resistance to thermal oxidation, , and unprecedented neutron shielding for space vehicles in the harsh outer atmosphere . In parallel, BNNTs possess comparable extraordinary mechanical properties to those of analogous CNTs .…”

Boron nitride nanotubes (BNNTs) have gained significant attention as a nanofiller additive to enhance the mechanical and thermal properties of polymer composites. However, despite the advancements in BNNT large-scale synthesis methods, the inherent hydrophobicity and the presence of van der Waals attraction hinder their potential application due to poor dispersion in polar and/or nonpolar solvents. In this communication, a facile deposition approach of plant-based polyphenols intercalated with an amine source was postulated. Given the economic advantage and ease of deposition, tannic acid (TA) was directly deposited onto the BNNT surface to enunciate hydrophilic attributes. Afterward, decylamine (DA) was introduced into the BNNT-TA (BNNT-TA−DA) to heighten the BNNT interaction with the polymeric system. The dried BNNT-TA and BNNT-TA−DA powders can be readily redispersed at various concentrations in polar and nonpolar solvents, enhancing the BNNT dispersion and interaction with the polymeric matrix to improve the composite performance. Moreover, to demonstrate the interfacial modification viability, BNNT-TA−DA was used as a filler in epoxy resin to form polymer composites. The fabricated composites displayed 26.8% tensile stress and 52.2% breakpoint of strain increases compared to those of the neat polymer at 1 wt % loading.
