MXenes are a group of novel two-dimensional (2D) materials with merits such as large specific surface area, abundant surface-functional groups, high chemical activity, excellent mechanical properties, hydrophilicity, and good compatibility various polymers. In recent years, many high-performance organic anticorrosion coatings using nanofillers have been reported attracted widespread attention. As the first successfully prepared MXene material, Ti3C2Tx is most extensively studied typical member family. Therefore, it taken representative its family, status MXene/epoxy resin (EP) MXene/waterborne polyurethane (WPU) polymer anticorrosive composite reviewed. Firstly, structure, characteristics, main synthesis methods briefly introduced. Then, latest progress four surface-modification strategies to improve dispersion, compatibility, stability, anti-aggregation properties MXenes, namely functionalization grafting, orientation regulation, heterostructure nanocomposite design, stabilization greening treatment, analyzed summarized. Finally, current challenges future opportunities regarding MXene-based corrosion-resistant discussed prospectively.

Abstract In this study, the interfacial interaction between 3‐aminopropyltriethoxysilane (APTES) modified basalt fibers (BF@A x ) and waterborne epoxy was studied by using thermodynamic approaches creating a “wetting‐reagglomeration‐adsorption” isocontour map of epoxy. Combined with TG‐DSC, dynamic thermomechanical analysis (DMA), tensile, flexural, electrochemical impedance spectrum (EIS) salt spray tests, enhancement effects on thermal stability, mechanical properties corrosion resistance were demonstrated. From map, APTES modification reduces surface energies BF@A fillers from 53.05 to 50.27 mJ/m 2 , which results in driving energy for reagglomeration decreasing 17.04 10.41 adsorption increasing 20.24 20.77 suggesting that BF fillers' dispersion performance strengths composite coatings are enhanced. Compared varnish coating, tensile flexural (EP)/BF@A 9.5 coating increased 55.87% 36.36%, respectively, stability is enhanced, due optimal dispersion. Meanwhile, EP/BF@A 5.0 has best | Z 0.01Hz value above 10 9 Ω cm after 35 days exceeding 120 days. This work provides new insight into how one‐dimensional rod matrices affects composites' thermodynamics. Highlights Waterborne reinforced chopped BFs. Impact uncovered.

Iron corrosion is very common in our daily life, and its effective protection can extend service life. As a small molecule monomer, 2-hydroxyethyl methacrylate phosphate (HEMAP) has group that effectively chelate with iron ions to form passivation layer (iron phosphate), thus slowing down the rate of iron. This study synthesized HEMAP-modified acrylic-alkyd resin copolymers variable concentrations using free radical polymerization. The addition HEMAP not only increases cross-linking density resin, but it also further strengthens adhesion between resins substrate, which prevents corrosive substances from penetrating resin. According electrochemical studies, adding 2% mass fraction could greatly increase resistance corrosion. reveals HEMAP's capacity enhance coatings on substrates lengthen metal's
