Abstract

Abstract : Front Cover : In article number 2000527 by Faai Zhang and co‐workers, a crosslinked polymer blend based on a urethane‒arcylate system with a combination of reversibly noncovalent intrachain and interchain hydrogen bonds and dynamically covalent urea bonds is developed through a facile in situ photoinduced copolymerization. The materials exhibit rapid self‐healing at mild conditions (70 °C, 30 min), extreme toughness (≈34.76 MJ m −3 ), high tensile strength, superior stretchability, long‐term stability, recyclability, and weldability.
