Research Institution
Specialty polymer coatings are widely used for maintenance applications, such as for bridges, refineries, power plants, ships, industrial floors, and fuel tanks. Due to routine wear and tear, micro-damage or micro-cracks within the resin matrix can be generated, which eventually lead to macroscopic damages (e.g., rupture and delamination) and reduce the operational life of the coatings. Currently available self-healing coatings are designed to heal only surface scratches through an elastic recovery of the material via utilization of stored energy. However, these coatings are unable to self-repair mesoscopic (e.g., micro-cracks and cavitation) and macroscopic damages. This project will develop a generic technology that can repair micro-cracks through a heat-stimulated simultaneous crack closing and sealing process. The approach will be based on a polymer nanocomposite coating that has a unique morphology. Phase I will demonstrate the feasibility of the approach by comparing the self-healing efficiency to that of currently available technologies. Commercial Applications and other Benefits as described by the awardee: The proposed self-healing nancomposite coating technology has immense potential in a broad range of industrial applications, including maintenance paints, marine coatings, and other special purpose coating applications. Reduction in the frequency of the repainting job not only would be cost-effective but also would help the environment by reducing the consumption of raw materials and the emission of VOCs (because solvent-borne coatings are still the leading coating category in the U.S.)
