Materials with self-healing abilities have gained tremendous attention in recent years but combing excellent mech. performance and splendid self-healing capacity into a single polymer material is still a great challenge. In this study, a self-healing polyurethane (SHP) material was prepared by constructing a dynamic crosslinked network via quadruple hydrogen bonds formed from 5-(2-hydroxyethyl)-6-methyl-2-aminouracil (UPy). The mech. properties of the materials could be conveniently tuned by adjusting the dynamic crosslinked d. The optimal sample, SHP-75, has excellent mech. performance, showing high tensile strength (27.02 MPa), excellent stretchability (1300%), and prominent toughness (111.37 MJ m-3). Despite such great mech. properties, SHP-75 exhibited superior self-healing abilities and could fully obtain its initial mech. strength after repairing at 80°C for 24 h. A self-healing conductive electrode was further constructed to demonstrate its application prospects in the field of sensing.
