Development and Characterization of Self-Healing Polyurethane Nanocomposite Coatings Incorporating Microencapsulated Corrosion Inhibitors for Marine EnvironmentsBy Kavitha Priya. D, L. Jayalakshmi, Janakan S. Saral, S. Rammohan, D. Sudha, Karthi G
Abstract: Chloride ions, dissolved oxygen, moisture and cyclic mechanical damage all infiltrate protective coatings and cause localized corrosion to occur in marine steel structures, resulting in continuous degradation. In this study, a self-healing polyurethane nanocomposite coating is developed by using microencapsulated corrosion inhibitors and the formulation effects are investigated using the Response Surface Methodology and Electrochemical Impedance Spectroscopy techniques. Using a Box-Behnken design, loading of microcapsules and hexagonal boron nitride nanofiller, …
