“…Its tribological behavior has been the subject of numerous studies. [20][21][22][23][24] It has been stated that BNNSs added to the PVA hydrogel formulation perform better in thermal recovery capacity and improve mechanical properties. 25 Studies on the toxicity of hBN nanoparticles are very recent and limited.…”

Hyaline cartilage can be defined as a “biological bearing material” with an engineering approach. Movement causes friction between joints while lubricants provide separation between the two surfaces, reducing or preventing frictional wear. This study describes an injectable hybrid hydrogel consisting of a hyaluronic acid matrix filled with hexagonal boron nitride (hBN) particles that can mimic the rheological properties of joint fluid. hBN is a good lubricant and a strong candidate for biomedical applications with its unique tribological properties. The hypothesis established is that the lubricating property of hBN may alleviate the symptoms of osteoarthritis (OA) and improve the person's life quality. A new formulation and strategy for articular injections are proposed. The focus of the present work is the presentation of the rheological profile of hyaluronic acid‐boron nitride (HA‐hBN) hybrid hydrogels. Structural and physical characterizations have shown that BN‐HA hybrid hydrogels can be produced in injectable form, their compatibility with HA strongly depends on surface modification of BN, and they are promising candidates for the treatment of OA by evaluating the frequency range of walking and running.

“…11(a), it can be seen that when using pure mineral oil as a lubricant, the worn surface shows a large wear scar with wide furrows. Black pits, cracks, and wear debris were also observed, illustrating that the wear mechanism was abrasive wear [19]. Compared with the effect of pure oil, both the size and furrow width of the wear scars after lubricating with BTB or BMB incorporated oil were smaller.…”

“…To show the excellent tribological properties of h-BN due to the interlayer slip, Xiaojing et al used it as lubricant additive to Gas to Liquid-8 (GTL-8) as base oil [171]. Boron Nitride nanosheets were synthetized by molten alkali-assisted exfoliation and the mixture (2.84 g NaOH, 2.16 g KOH and 1 gr h-BN) was maintained in reactor for 2 and 6 h in 180 • C, and samples were respectively named BNNS-1 and BNNS-2.…”

Recent Progress in the Study of Thermal Properties and Tribological Behaviors of Hexagonal Boron Nitride-Reinforced Composites

Ever-increasing significance of composite materials with high thermal conductivity, low thermal expansion coefficient and high optical bandgap over the last decade, have proved their indispensable roles in a wide range of applications. Hexagonal boron nitride (h-BN), a layered material having a high thermal conductivity along the planes and the band gap of 5.9 eV, has always been a promising candidate to provide superior heat transfer with minimal phonon scattering through the system. Hence, extensive researches have been devoted to improving the thermal conductivity of different matrices by using h-BN fillers. Apart from that, lubrication property of h-BN has also been extensively researched, demonstrating the effectivity of this layered structure in reduction of friction coefficient, increasing wear resistance and cost-effectivity of the process. Herein, an in-depth discussion of thermal and tribological properties of the reinforced composite by h-BN will be provided, focusing on the recent progress and future trends.
