| Research Abstract |
Self-healing coatings using functional nanomaterials and organic healing agents were developed to prevent corrosion of metallic materials. Nanomaterials(nanoparticles, nanofibers, nanoflakes) and organic healing agents were added in polymer, and these were coated on the surface of metallic materials. Corrosion tests of scratched coatings were conducted. Corrosion resistance of the specimen increased, resulting in self-healing capability of the coatings. Coatings of nanoporous materials and healing agents also showed self-healing capability. The healing film of organic healing agents could be observed on the scratched surface of specimen after corrosion test.
