Abstract
Addressing the conflict between achieving high mechanical properties and room-temperature self-healing ability is extremely significant to achieving a breakthrough in the application of self-healing materials. Therefore, inspired by natural spider silk and nacre, a room-temperature self-healing supramolecular material with ultrahigh strength and toughness is developed by synergistically incorporating flexible disulfide bonds and dynamic sextuple hydrogen bonds (H-bonds) into polyurethanes (PUs). Simultaneously, abundant H-bonds are introduced at the interface between graphene oxide nanosheets with dynamic multiple H-bonds and the PU matrix to afford strong interfacial interactions. The resulting…
