| Abstract Scope |
It is highly desirable, although very challenging, to develop self-healable coating materials with both high mechanical characteristics and excellent self-healing properties at ambient conditions. This study developed a novel zinc (II)–dimethylglyoxime–urethane-complex-based polyurethane elastomer with synergetic triple dynamic bonds. This exhibits the higher mechanical performance for self-healing elastomers at room temperature along with stability in adverse environments of the sewer system. Notably, it spontaneously self-heals at room temperature, demonstrating an instantly recovered tensile strength of 1.0 MPa and a continuously increased strength, reaching 9.2 MPa. Density functional theory calculations underscore the critical role of Zn(II) coordination in accelerating the reversible dissociation of dimethylglyoxime–urethane, contributing to the excellent performance of the self-healing elastomer. The application of this technology is showcased through a self-healable and stretchable coating for preventing fat, oil and grease deposition and concrete corrosion in sewer systems. |
