“…The diffraction peaks of the MXene were at 7.06 • , 14.20 • , 28.66 • , 35.82 • , 40.88 • and 61.06 • , corresponding to the crystal planes (002), (004), (008), (0010), ( 0012) and (110), which was consistent with the literature [45]. Additionally, the pink line in the XRD pattern of Figure 3a [46], respectively. The presence of N-B indicates that BN was successfully recombined to MXene.…”

“…As exhibited in Figure 3c, the C 1s peak at 284.86 eV could be deconvolved into three bands at around 284.71 eV, 285.01 eV and 287.45 eV, corresponding to three different chemical states of carbon atoms, which were bonded to C, N and O. The appearance of C-N peaks indicates that MXene was doped with N. As exhibited in Figure 3d, the N 1s spectrum of MXene/BN-201 was deconvolved into three peaks corresponding to N-B (397.02 eV), B-N-C (395.74 eV) and oxidized N-Ti (393.58 eV) [46], respectively. The presence of N-B indicates that BN was successfully recombined to MXene.…”

The challenge of developing a high-efficiency microwave absorbent remains, because of the compatibility between microwave absorption and high-temperature-resistant performance in practical application. Herein, a facile method is used to obtain serial MXene/BN-zxy composites, where zx:y indicates the weight ratio of MXene and boron nitride (BN) in the composites, with adjustable microwave absorption performance (MAP) which can be regulated by the ratio of MXene and the BN nanosheet. In particular, the as-prepared absorbents with supercapacitance-like structure significantly enhanced the MAP and could be served more than 900 °C. The results of MAP reveal that the minimum reflection loss (RL) can reach −20.94 dB with a MXene/BN-101 composite coating thickness of 4.0 mm; the effective attenuation bandwidth (RL< −10 dB, i.e., 90% microwave energy is attenuated) is up to 9.71 GHz (7.94–17.65 GHz). From a detailed analysis, it is observed that attenuation is the critical limiting factor for MAPs rather than impedance mismatch, which can be assigned to the poor MAP of BN nanosheets. In any case, as-prepared absorbents have potential applications in the field of heating components.

“…No corrosion was observed on the hybrid-treated sample after six months of air exposure. Significantly enhanced high-temperature oxidation resistance was also noted [ 71 ]. A comparative study on 2D graphite, BNNS and MoS 2 together with PVDF showed that BNNS was far superior to graphite and was marginally inferior to MoS 2 as an anti-corrosion coating for stainless steel [ 72 ].…”

“…The tribological properties depended on the friction conditions and the formation of tribofilms [18]. The h-BN is usually used as a solid lubricant component in the composite and is used for hightemperature tribological applications [19][20][21][22][23]. In previous research, h-BN coatings were manufactured on steel, and the results showed that the coatings were helpful at enhancing the tribological properties of steel at high temperatures [8].…”

The high-temperature superlubricity performances of h-BN coatings on the nontextured and textured surface of an Inconel X750 alloy is reported in the present paper. The hardness and bond strength of the h-BN coating and alloy were investigated. The tribological properties of the X750 alloy and coatings on the X750 alloy substrate were investigated at different temperatures. The surface texture was manufactured on the surface of the X750 alloy, and then coatings were deposited on the textured surface to reduce the cracking of the coating and enhance the stability of the antifriction behaviors of the h-BN coatings. The tribotest results showed that the texture is helpful to enhance the interface thermal compatibility of the coating and substrate and store the wear debris generated during sliding. Therefore, a stable superlubricity was achieved at high temperatures, and a super low friction mechanism is also discussed.
