Development of self-healing anti-corrosion coatings using functional nanomaterials

为了防止金属材料的腐蚀，开发了使用功能性纳米材料和有机修复剂的自修复涂层。将纳米材料（纳米颗粒、纳米纤维、纳米片）和有机修复剂加入聚合物中，并将其涂覆在金属材料表面。进行了划痕涂层的腐蚀试验。试样的耐腐蚀性提高，从而使涂层具有自修复能力。纳米多孔材料和愈合剂的涂层也显示出自愈合能力。腐蚀试验后，在划痕表面可观察到有机修复剂的修复膜。

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.
