N2 - Elastomers that combined excellent mechanical performance and healability are essential to the advancement of stretchable electronics. However, the strength and toughness of healable elastomers tend to be mutually exclusive. Herein, a new strategy of the dynamic integrated moiety is developed to construct covalent and noncovalent cross-linked polyurethane (CNPU) elastomers. The covalent and noncovalent interactions synergistically enhance the overall mechanical properties of polyurethane elastomers such as tensile strength (48.8 MPa), toughness (282.9 MJ·m-3), stretchability (1740%), and healing efficiency (116%). Finally, elastic conductive wires are fabricated with high load capacity, stable electrical conductivity under static/dynamic stretching, and robust healability to demonstrate the potential use of CNPU elastomers in stretchable electronics.
