Self-Healing (Self/Autonomic Repairing) is a property of materials that heals automatically from all types of damage. This property can recover the strength and extend the service life of materials through repairing damage. There are many developments about self-healing polymers, but in most studies, self-healing occurs under high temperature and constant pressure. In this study, we developed thermoplastic polyurethanes that can be healed at moderate conditions due to dual mechanisms. The synthesized thermoplastic polyurethane contains multiple self-healing moieties that act as supramolecular interactions and dynamic covalent bonds enabling thermoplastic polyurethane to be healed in short time at room temperature. Also, the mechanical properties of polymers were improved by multiple hydrogen bonding monomers. These self-healing polymers can be used in a variety of fields such as surface protective coatings, medical materials and wearable sensors. |
