| Popis: | Self-healing synthetic polymers have attracted considerable scientific attention owing to their excellent durability and extended lifetimes. Among the categories of extrinsic and intrinsic self-healing, the intrinsic process is being focused on recently because it can realize rapid and reversible self-healing abilities and repeatability through dynamic chemical bonds. Intrinsic self-healing was categorized into two types: reversible covalent and non-covalent bonding, which include reversible cycloaddition reactions, exchange reactions, hydrogen interactions, and metal-ligand coordination interactions. This review focuses on recent studies about self-healing polyurethanes, which are known to exhibit remarkably high elasticity, high tensile strength, low-temperature resistance, and corrosion resistance. The various methods used for realizing efficient self-healing polyurethanes are also explored. |
