Achieving ultrafast resilience comparable to that of irreversible cross-linking elastomers remains a formidable challenge for self-healing supramolecular elastomers. Herein, we construct π-type tweezer structure formed by imidazolidinylurea and aromatic imine stabilize dynamical hard domains (SDHDs) in polyurethane (PU) SDHDs endow the dynamic PU network with high binding energy minimal stress relaxation at room temperature, similar covalent cross-links. As such, elastomer demonstrates rapid vulcanized natural rubber as well mechanical strength toughness. Meanwhile, can be readily activated upon heating, enabling exceptional healing ability (∼100% efficiency) under mild conditions (50 °C) complete recovery properties after recycling. More interestingly, exhibits significant elastocaloric effects an adiabatic temperature change −13.5 °C, surpassing state-of-the-art (−9.4 °C). Therefore, this work presents new approach structural design enables balance between conflicting characteristics expands potential applications

Integration of sensing and actuation capabilities into flexible electronics is critical to expanding their applications. Existing stimuli-responsive polymers fail achieve satisfactory requirements, considering strength–toughness trade-off, conductivity, recyclability. Here, a novel elastomer reported by molecular design, thus simultaneously enabling the effective unification functions. The realizes high strength (32 MPa), stretchability (527%), toughness (74.8 MJ·m–3), fracture energy (75,300 J·m–2), efficient recyclability processability, puncture-resistance, conductivity (120.1 S·m–1) where conductive created incorporating both dynamic covalent bonds (strong bonds)/coordination (weak bonds) for formation adaptive networks coated ink. In parallel, benefiting from mechanism its architecture, elastomer-enabled sensor actuator exceptional performance as green strain monitoring body movements excellent ability self-sensing load-carrying. Overall, this comprehensive brings new inspiration insights design next-generation e-skin, robots, other materials.
