Elastomers with excellent mechanical properties are in substantial demand for various applications, but there is always a tradeoff between their strength and stretchability. For example, partially replacing strong covalent crosslinking by weak sacrificial bonds can enhance the stretchability also usually decreases strength. To surmount this inherent tradeoff, supramolecular strategy of introducing zipper-like sliding-ring mechanism hydrogen-bond-crosslinked polyurethane network proposed. A...
