The outstanding mechanical properties and self-healing properties of materials are theoretically mutually exclusive, so developing elastomers that combine these two characteristics is a significant challenge. Herein, a high-strength, tough, and room-temperature self-healing rosin-based polyurethane thermoplastic elastomer with a stress of 45.25 MPa, a substantial fracture strain of 1647%, and a superior toughness of 326.65 MJ m− 3 was prepared by molecular design. The introduction of rosin increases the free volume …
