Intelligent self-healing coatings are at the forefront of corrosion protection research for marine engineering globally. We present innovative approaches using functional nanofibers to create advanced self-healing coatings. One strategy employs photothermal and corrosion self-healing based on multifunctional fibers. Electrospun fibers act as templates where photothermal agents and tannic acid, a corrosion healer, form a core-shell structure. These fibers, embedded in a thermoplastic resin, yield a responsive self-healing coating. When damaged, the fibers release healing agents that react with metal ions, filling cracks. Sunlight triggers photothermal agents, healing damage within 100 seconds. Another approach combines nanofibers with corrosion indicators for visible damage detection. These fibers, integrated into an epoxy resin, release indicators upon cracking, signaling corrosion and enabling timely repairs in marine environments.
