“…Since the publication of our paper on autonomic self-healing of polymer composites in 2001 [6], the Web of Science lists more than 6000 publications covering the field of self-healing materials. These publications reported on self-healing chemistries in different kinds of materials, including thermoplastic polymers, thermoset polymers, elastomers, shape memory polymers, supramolecular polymers, polymer composites, nanocomposites, and coatings [7][8][9][10][11][12]. Inspired by a variety of natural materials, research in synthetic self-healing materials focuses on the preparation of multifunctional materials that are able to recover their fundamental properties including mechanical strength, conductivity, fracture toughness, and corrosion resistance, after damage has occurred [5].…”
