‘Self-healing’, a nature-inspired phenomenon, has been integrated into various materials including structural components, coating, and films. Materials scientists have been interested in designing functional materials that could repair damage independently during their service life to reduce the maintenance cost and ensure safety.

This bio-inspired phenomenon includes potential smart and intelligent materials like self-repairing paints for automobiles, self-recovering screens for mobile phones, self-repairing coatings for oil and gas pipelines, and many more. Recently, with the aim of developing multifunctional smart materials for electronics, construction, automobile, and biomedical applications, researchers have focused on integrating a self-repairing capability into polymers, ceramics, and concrete.

The aim of this Special Issue is to cover emerging areas on self-healing nanocomposites, including strategies adopted to develop self-healing abilities in nanocomposites, self-healing polymer nanocomposites, self-healing coatings and films, multifunctional nanocomposites which integrate self-healing ability along with other smart functionalities, etc. Additionally, review articles on self-healing nanocomposites and coatings are welcome.

Potential topics include but are not limited to the following:

• Self-healing polymer nanocomposites
• Self-healing strategies and techniques
• Self-healing for anti-corrosive nanocomposite coatings
• Self-healing films and membranes
• Self-healing coatings for biomedical implants
• Self-healing textiles
