Development and characteristics of UV-photocurable anticorrosive MXene coatings

The instability of UV anti-corrosion coatings poses a significant threat to both air quality and the environment, highlighting the urgent need for efficient and eco-friendly anti-corrosion coatings. In this study, we synthesized a novel material, MXene, known for its well-defined layered structure and exceptional conductivity, by employing a MAX phase etching process. Our investigation encompassed the assessment of MXene’s compatibility within UV coating systems, as well as its dispersion and stability within composite coating systems. We observed that MXene’s substantial specific surface area and robust chemical adsorption capabilities played pivotal roles in the adsorption and stabilization of nanoparticles within the UV coating. Further exploration of MXene-based UV-curable anti-corrosion coatings revealed remarkable resistance to hydrogen-induced corrosion due to MXene’s outstanding electrical conductivity and its ability to regulate surface chemical reactions. This optimization not only enhances UV-curing and photostability performance in UV anti-corrosion coatings but also makes them highly suitable for producing efficient anti-corrosion coatings. This approach demonstrates broad applicability across various substrates where superior corrosion resistance is essential.
