“…91–94 °C for the composite films after mixing BNNS in the PEF matrix. This is because the presence of BNNSs effectively decreases the free volume of composite films and prevents the movement of PEF chains . On the other hand, due to the increased movement of PEF chains at high temperatures, thus the T m values of the composite films only show a slight increase from ca.…”

“…Hence the detailed measurements and analysis of gas barrier properties of the BNNS/PEF composite films are conducted. Before testing, the relationship between the pathway (defined as tortuosity, τ) of the gas permeation in the films and the filler content of the composite films was calculated as follows τ = 1 + L 2 D × φ × 2 3 ( S + 1 2 ) Where, L and D are the lateral size and thickness of the BNNS, respectively, S represents the orientation degree ( S = 1), and φ is the mass content of the filler.…”

Developing sustainable plastics, for instance, green poly(ethylene 2,5furandicarboxylate) (PEF), is a promising pathway to decrease the reliance on petroleumbased plastics and the pollution of the environment. However, the preparation of highperformance PEF materials that integrate superior barrier and mechanical properties remains a huge challenge. In this study, a BNNSs/PEF composite film with excellent mechanical and barrier performance was fabricated by using furfuryl alcohol simultaneously acting as a high-level dispersant and interfacial reinforcement matrix for BNNSs. The optimized BNNS/PEF composite film with 0.2 wt % BNNSs (BP2) shows a compacted aligned structure and excellent comprehensive performance with 79.2 MPa tensile strength (43% enhancement), 4.2 GPa Young's modulus (83% enhancement), high gas barrier, and enhanced thermal stability. Remarkably, fruit testing conditions (e.g., relative humidity of 90−95%, temperature of 30, and natural light) showed that the BP2 composite film extended the shelf life of fresh strawberries by at least at least 5 days in an ambient environment. The overall performance of the BP2 composite film is optimized to be superior, which opens up an avenue for practical applications in the field of packaging materials.

“…In recent years, Ti 3 C 2 T X Mxene had become a research hotspot in the field of anticorrosion and lubrication because of its excellent impermeability, lubricity, and environment friendliness. − Meanwhile, the large specific surface area and thermal stability of MXene enable it to be used as a functional filler for organic coatings, improving the density and wear resistance of coatings. , MXene prolonged the diffusion path of a corrosive medium by constructing a “maze effect” in the coating, which improved the corrosion resistance of the coating. − Therefore, MXene has broad application prospects in the field of metal protection. Yan et al used dimethyl sulfoxide (DMSO) to intercalate accordion-like MXene and obtained MXene with fewer layers and larger layer spacing by means of ultrasonic oscillation.…”

MXene has excellent anticorrosion and self-lubricating properties. It is widely used in the field of anticorrosion and wear resistance. However, there is a strong interaction between MXene nanosheets, which makes it easy for them to agglomerate in the coating and affects the mechanical properties of the coating. Thus, the application of MXene is limited. In this study, MXene is modified by 2,5-diaminobenzenesulfonic acid, which can reduce the aggregation of MXene in the coating. MXene is functionalized by using tetrabutylphosphorus hydroxide benzotriazole lignin composite material (BTA-P4444-Lig) with environmental protection, anticorrosion, and lubricating properties. The prepared MXene has excellent anticorrosion and lubrication properties. Functionalized MXene (f-MXene-P) is used as a filler for environmentally friendly waterborne epoxy (WEP) coatings. Electrochemical tests show that the impedance of f-MXene-P/WEP (3.91 × 107 Ω·cm2) is an order of magnitude higher than that of WEP (1.89 × 106 Ω·cm2). The maze effect of MXene and the protective film formed by BTA-P4444-Lig on the surface of Q235 steel synergistically enhance the anticorrosion performance of f-MXene-P/WEP. The friction test results show that the friction coefficient of f-MXene-P/WEP (0.068) is much lower than that of WEP (0.612). The synergistic effect of MXene and BTA-P4444-Lig with lubricating properties improves the wear resistance of f-MXene-P/WEP.

The development of nanomaterials is crucial to upgrading of modern industry. MXene nanosheets have attracted significant attention due to their superb resistance to permeation, diverse surface chemical properties, impressive mechanical properties, and metal‐like electrical and thermal conductivity, etc., providing unique advantages in various technical fields. When MXene nanosheets are combined with polymers to form functional coatings, their applications span multiple fields, including anticorrosion, wear resistance, flame‐retardancy, electromagnetic interference (EMI) shielding, and de‐icing. This review, in conjunction with MXene's barrier property, lubricity, thermal stability, conductivity, and photothermal conversion property, discusses in detail the various applications of MXene‐based polymer coatings. Additionally, it examines the dispersion and interaction of MXene within polymer coatings and the role of functionalized MXene in polymers. Finally, based on the current research status and emerging needs, the development challenges and future research opportunities of MXene‐based polymer coatings in a targeted manner are discussed. This review aims to summarize the existing research results and put forward an objective and fair point of view, providing a constructive reference for upgrading modern nanofunctional polymer coatings.
