“…BN is a refractory compound with heat and chemical stability having high thermal conductivity, high electrical resistivity, non-wettability, excellent lubricating properties and low dielectric constant. [20,24,25] It has been revealed that wear resistance of polymer can be improved by incorporating hydrophobic BN due to its lubricious nature. Also the high temperature resistance and low density properties makes them suitable for electronic packaging application.…”

Recently, boron nitride (BN) based materials have received significant attention in both academic and industrial sectors due to its interesting properties like large energy band gap, good resistance to oxidation, excellent thermal conductivity, thermal stability, chemical inertness, significant mechanical property and widespread applications. This review article deals with the preparation and properties of boron nitride and its nanocomposites with various polymers. Diverse polymers have been explored for the preparation of boron nitride filled polymer nanocomposites by adopting different mixing methods. Properties of the resulting polymer nanocomposites mainly depend up on filler size and dispersion, mixing conditions and type of interaction between polymer matrix and the filler. Herein, the structure, preparation and properties of various boron nitride based polymer nanocomposites are reviewed in detail along with a brief overview of different classes of BN nanomaterials.

“…Moreover, as evaluating temperature increased, the value of thermal conductivity was higher than the single component nanofluids [ 77 , 78 ]. h-BN contributed to the increase of the thermal conductivity as well as MoS 2 , promoting the dispersion of the nanostructures due to their lubricant properties [ 38 , 79 ].…”

In this paper, the thermal conductivity behavior of synthetic and natural esters reinforced with 2D nanostructures—single hexagonal boron nitride (h-BN), single molybdenum disulfide (MoS2), and hybrid h-BN/MOS2—were studied and compared to each other. As a basis for the synthesis of nanofluids, three biodegradable insulating lubricants were used: FR3TM and VG-100 were used as natural esters and MIDEL 7131 as a synthetic ester. Two-dimensional nanosheets of h-BN, MoS2, and their hybrid nanofillers (50/50 ratio percent) were incorporated into matrix lubricants without surfactants or additives. Nanofluids were prepared at 0.01, 0.05, 0.10, 0.15, and 0.25 weight percent of filler fraction. The experimental results revealed improvements in thermal conductivity in the range of 20–32% at 323 K with the addition of 2D nanostructures, and a synergistic behavior was observed for the hybrid h-BN/MoS2 nanostructures.

“…Traditionally, aerogel is perceived as a superlight material being of extremely low thermal conductivity, which has overwhelming advantages in fields requiring super thermal insulation (Hu et al, 2019;Illera et al, 2018;Tychanicz-Kwiecie n et al, 2019). Contrary to the general aerogel, BN per se is well known for its brilliant thermal conductivity (Sharma et al, 2020). When the two extremes are combined, which side would the integrated BN aerogel stand?…”

The rise of ceramic aerogel offers traditional ceramics a new window. Alongside the emerging prospects, what is open to explore includes the elegant design of a ceramic aerogel with tailorable inner organizations, what would occur when complex hierarchy exists in such an already intricate system, and how the properties get influenced as the complexity fades. Borrowing the wisdom from supramolecular world, we exquisitely transform BN aerogel from a complex hierarchy to a flatten microstructure based on solvent-induced morphology switch of its supramolecular precursor gel. Such reduction in structural hierarchy has insignificant effect on the thermal conductivity ($0.027 W/(m$K)) but shifts the wettability from hydrophobicity to hydrophilicity and occasions nearly 3-fold difference in ion adsorption rate, as exemplified by lead ions. This work may promote the understanding of special hierarchy existing in delicate systems and inspire other attempts to harness the functionality of aerogels by manipulating structural hierarchy.
