Abstract Practical applications of existing self‐healing ionogels are often hindered by the trade‐off between their mechanical robustness, ionic conductivity, and temperature requirements for ability. Herein, this challenge is addressed drawing inspiration from sea cucumber. A polyurethane containing multiple hydrogen‐bond donors acceptors synthesized used to fabricate room‐temperature with excellent properties, high puncture resistance, impact resistance. The hard segments polyurethane, driven hydrogen bonds, coalesce into phase regions, which can efficiently dissipate energy through reversible disruption reformation bonds. Consequently, resulting exhibit record‐high tensile strength toughness compared other ionogels. Furthermore, inherent reversibility bonds within regions allows spontaneously self‐heal damaged properties conductivity times at room temperature. To underscore application potential, these employed as electrolytes in fabrication electrochromic devices, stable performance, repeatable healing ability, satisfactory This study presents a novel strategy exceptional capability.

Flexible conductive elastomers play a pivotal role in biosensing, electronic skin, and wearable devices. However, fabricating self-healing with superior mechanical properties remains formidable challenge. Here, we introduce simple strategy for the preparation of flexible elastomer that integrates stretchability, conductivity, capabilities. Initially, lipoic acid (LA) deep eutectic solvents (DES) are thermally initiated ring-opening copolymerized, yielding linear copolymer P(LA-DES). This polymer is then integrated polyurethane by intermolecular hydrogen bonds, followed incorporation Fe3+ ions to form dynamic cross-linked network containing disulfide metal coordination. supramolecular not only exhibits remarkable but also demonstrates stable reliable signal response capabilities when used as strain sensor.
