A multifunctional epoxy-based priming composite coating was developed using covalently engineered h-BN/Ti-MXene nanohybrids, further decorated with a novel porous dopamine–tungsten–molybdenum (W–Mo) nanocomplex, and loaded with a zinc-based corrosion inhibitor (ZMWD-MXene-BN). This coating exhibits outstanding physical barrier properties against corrosive agents, along with active self-healing capability. The developed nanohybrids were characterized through various tests, including field emission-scanning electron microscopy (FE-SEM), Fourier transform infrared spectroscopy (FT-IR), high resolution transmission electron microscopy (HR-TEM), X-ray photoelectron spectroscopy (XPS), X-ray diffraction (XRD), and Brunauer–Emmett–Teller (BET) theory. The inhibition efficiency toward corrosion of the ZMWD-MXene-BN nanohybrid in saltwater (NaCl media) was examined through electrochemical impedance spectroscopy (EIS). The results demonstrated a remarkable corrosion protection efficiency of 85.69% after 72 h of immersion. The epoxy coating containing the ZMWD-MXene-BN nanohybrid demonstrated exceptional protective performance. It exhibited superior barrier properties, maintaining an impedance value of 17.79 GΩ.cm² after an immersion duration of 70 days in a simulated seawater solution. Additionally, the coating showed active self-healing behavior, with about a 33% increase in total resistance after 48 h of exposure to saltwater. Its adhesion strength was also significantly enhanced, with improvements of about 65.8% in the wet pull-off strength and 71.46% in the cathodic delamination test.
期刊介绍：
Advanced Composites and Hybrid Materials is a leading international journal that promotes interdisciplinary collaboration among materials scientists, engineers, chemists, biologists, and physicists working on composites, including nanocomposites. Our aim is to facilitate rapid scientific communication in this field.
The journal publishes high-quality research on various aspects of composite materials, including materials design, surface and interface science/engineering, manufacturing, structure control, property design, device fabrication, and other applications. We also welcome simulation and modeling studies that are relevant to composites. Additionally, papers focusing on the relationship between fillers and the matrix are of particular interest.
Our scope includes polymer, metal, and ceramic matrices, with a special emphasis on reviews and meta-analyses related to materials selection. We cover a wide range of topics, including transport properties, strategies for controlling interfaces and composition distribution, bottom-up assembly of nanocomposites, highly porous and high-density composites, electronic structure design, materials synergisms, and thermoelectric materials.
Advanced Composites and Hybrid Materials follows a rigorous single-blind peer-review process to ensure the quality and integrity of the published work.
