Abstract
Abstract Elastomers are omnipresent in everyday life and industry, yet the development of an elastomer with both superb stress and toughness presents a prodigious challenge. In this report, a high‐strength, tough, and high‐elastic elastomer derived from sp 2 hybrid orbitals of phenylboronic acid was designed. The spatial conformation of network becomes significantly more compact due to the sp 2 hybridization of boron. This enhances supramolecular hydrogen bonding interactions, resulting in a marked improvement in the material's mechanical properties. Notably, the hydrogen bonding energy in the polyurethane chain segments enhanced by 37%. The robust hydrogen bonding imparts the elastomer with super high true…
