Abstract

Self-healing materials have created a special interest among researchers for their unique properties and versatile applications. Among different self-healing materials, nanostructured polymer composites are quite potential smart materials for different coating applications including surface coatings for biomedical applications. The present review reveals preparation, properties, and applications of self-healing nanoscale polymer-based coatings. Chemistry behind the self-heal nature of nanoscale polymer-based coating materials is briefly explained with different approaches for self-healing. The healing mechanism by the microcapsule and microvascular approach is discussed elaborately and schematically in the present chapter. Anticorrosion coating applications of self-healing polymer-based materials are established. The chapter also includes applications in electronic and electrochemical devices involving self-healing polymer-based coatings. Further, the properties and applications of shape memory materials are incorporated.
