Abstract Liquid‐free ion‐conductive elastomers with excellent mechanical and electrical conductivity are widely used in flexible sensors, wearable devices, soft touch screens, supercapacitors.

Abstract Polymeric materials often face inherent trade‐offs between mechanical performance and self‐healing capabilities, which presents significant challenges to their development practical application. Here, an effective strategy is reported overcome these limitations. By introducing a highly crystalline polyol—characterized by its chain folding storage length—and coordination bonds into polyurethane, exceptional balance of high tensile strength (47.18 ± 2.35 MPa), elongation at break (5952.72 254.20%), outstanding toughness (1396.39 90.05 MJ m −3 ), hardness (shore D 43.8 0.8) achieved, while also maintaining intrinsic properties. The material's facilitated the water solubility polyol (polyethylene glycol, PEG), enables rapid healing welding low temperatures (4 °C) with aid water. Additionally, shape‐memory recovery force further enhances crack closure healing, contributing durability. This unique combination capabilities underscores potential this material for advanced applications that require both properties robust functionality.
