Cover Story: Self-healing polymers and nanocomposites form an important class of materials having the ability to reversibly heal their damages. In the aerospace sector, thermosets/thermoplastic polymers filled with carbon nanoparticles have gained importance for self-healing of structural damage. Self-healing performance depends on the addition of nanocapsules or carbon nanoparticles, microphase separation, matrix–nanofiller interactions, and polymer–nanofiller inter-diffusion. Self-healing nanocomposites have found potential in aerospace structural components, panels, laminates, membranes, and coatings. Future high-performance self-healing nanocomposites may further broaden the scope of self-healing materials for aerospace structures. View this paper
