Super Tough and Spontaneous Water‐Assisted Autonomous Self‐Healing Elastomer for Underwater Wearable Electronics (Adv. Sci. 21/2021)

Underwater Wearable Electronics In article number 2102275, Cyuan‐Lun He, Fang‐Cheng Liang, Chi‐Ching Kuo and co‐workers present a novel underwater self‐healing polymer, based on synergistically dynamic covalent Schiff‐based imine bonds with hydrogen bonds, which is eco‐friendly, economical, waterproof, and resilient. It has outstanding performance in terms of stretchability (9050%), self‐healing efficiency (95%), self‐healing time (1 h at room temperature), and toughness (144.2 MJ m(−3)), giving it high potential for integration into underwater electronics.
