“…The results showed that the impedance modulus of BNNS/EP after soaking in 3.5 wt.% NaCl solution for 70 days was as high as 6.63 × 10 7 Ω cm 2 , indicating that the introduction of BNNSs made the EP composite coating have excellent long-term anti-corrosion performance. Similarly, Sun et al 25 also studied the effect of adding BNNSs on the corrosion performance of EP composite coatings. The research results show that the addition of BNNSs can enhance the corrosion resistance of the composite coating, and the corrosion resistance of the composite coating with .8 wt.% BNNSs content is the best.…”

A method of preparing SiO2‐BNNSs hybrid material by surface modification of boron nitride nanosheets (BNNSs) with SiO2 was proposed to improve the dispersion of BNNSs in the coatings. Then, phosphate ceramic coatings with BNNSs and SiO2‐BNNSs were prepared on stainless steel (304) by spraying. Characterization of BNNSs and SiO2‐BNNSs by X‐ray diffraction, Fourier transform‐infrared, Raman, and scanning electron microscopy proved the success of hybridization. The surface morphology and mechanical properties were conducted to characterize the protective performance of the coating. Simultaneously, the phase composition and electrochemical properties of the coatings after high‐temperature oxidation were studied. The results showed that ceramic coatings had low surface energy with a contact angle of 102.41° when .4 wt.% SiO2‐BNNSs was added. Compared with BNNSs coating, the mechanical properties of SiO2‐BNNSs coating were significantly enhanced, the hardness of .4 wt.%SiO2‐BNNSs coating was as high as 170 HV, and the interface bonding strength was 12.24 MPa. For the oxidation corrosion resistance, .4 wt.% SiO2‐BNNSs coating under oxidation at 400°C for 50 h had the minimum corrosion current density and maximum impedance, which were .864 μA/cm2 and 177 kΩ/cm2, respectively, this indicated that SiO2‐BNNSs coating could still maintain excellent oxidation corrosion resistance under high‐temperature conditions for a long time.

“…Since the preparation of graphene (Gr) through mechanical exfoliation from pristine graphite in 2004, two-dimensional (2D) materials have exhibited great application promise in numerous fields of science and technology. − Hexagonal boron nitride (hBN), an isoelectronic analogue of Gr, also called “white graphene,” possesses many fascinating properties like high barrier property, thermal/chemical stability, thermal conductivity, mechanical strength, adsorption capability, and biocompatibility . hBN nanosheets (BNNSs) usually act as building blocks for various functional constructions of macroscopic composites in super extensive applications, including corrosion protection, − thermal management, − friction resistance, energy storage, and drug delivery . The production of high-quality and large-size ultrathin BNNSs is a presupposition to fully utilize the superior properties in the above-mentioned applications.…”

Hexagonal boron nitride nanosheets (BNNSs) show great applications in metal protection, thermal management, energy storage, and medicine fields due to their many unique properties. However, the scalable preparation of large-size ultrathin BNNSs still remains a huge challenge to date. This study develops a sustainable mechanochemical exfoliation (SMCE) approach for high-yield (74%) synthesis of BNNSs by polylactide-assisted ball milling from bulk hexagonal boron nitride (hBN). The obtained BNNSs have an ultrahigh aspect ratio of ≈1240 and a low defect degree and show superior disperse ability in liquids. Combining experimental and density functional theory (DFT) results, a reasonable mechanism of edge-selective grafting is proposed. In view of the excellent processability and selfassembly ability of such large-size ultrathin BNNSs, high-performance and transparent BNNSs/epoxy (EP) composites with greatly improved anticorrosion and mechanical properties are then fabricated. Typically, the BNNSs/EP composites show an extremely high protection efficiency of 99.9%, and the tensile strength and modulus increase by 124 and 66%, respectively. We believe that this green and efficient exfoliation route will boost the development of scalable production of large-size ultrathin BNNSs and shows huge promise for their widespread application in functional composites.

“…After the successful preparation of graphene, other two-dimensional (2D) nanosheets such as boron nitride, molybdenum disulfide, black phosphorus, and MXene have garnered significant interest in various fields due to their exceptional properties, including 2D superconductivity, direct band gap, and quantum spin Hall effect [1][2][3][4][5][6]. For instance, boron nitride nanosheets (BNNSs) are often referred to as 'white graphene' due to their remarkable thermal conductivity, stability, impressive mechanical properties, and wide band gap, which attributes them useful in a variety of applications, such as dielectric substrates, electronic packaging, and high −power devices [7][8][9][10][11]. White mica is a naturally occurring layered silicate material, consisting primarily of Al 2 O 3 and SiO 2 .…”

The efficient exfoliation of mica, a naturally layered material, into two-dimensional (2D) nanosheets has received much attention due to its low price, good chemical stability, and better shielding function against UV light. However, fast and simple exfoliation of mica in a large-scale face a great challenge. In this work, we developed a simple and effective method for obtaining OH−functionalized mica nanosheets (MNs). The process involved calcination, plasma treatment, and ultrasonic exfoliation, resulting in a yield of 7.535%. Furthermore, the effects of sonication time, solvent type, and particle sizes of mica were investigated. The conditions for the preparation of MNs were determined: mica calcination, plasma treatment, and sonication in ethanol for 5 h. XPS and FT−IR demonstrated that more hydroxyl groups were introduced to mica after the plasma treatment, which facilitated the exfoliation of mica.
