Eutectogels are recently emerged as promising alternatives to hydrogels owing their good environmental stability derived from deep eutectic solvents (DES). However, construction of competent eutectogels with both high conductivity and mechanical toughness is still difficult achieve yet highly demanded. In this work, new LMNP-PEDOT-CMC-AA (LPCA) prepared using acrylic acid (AA) carboxymethylcellulose sodium (CMC) polymeric networks, liquid metal nanoparticle-poly(3,4-ethylenedioxythiophene) (LMNP-PEDOT) added multifunctional soft fillers. Benefiting the compliant conductive LMNP-PEDOT, LPCA exhibit (0.224 S m-1), electromechanical coupling, stretchability (4228%) exceptional (7.278 MJ m-3). Additionally, abundant hydrogen interactions available functional groups within endow them excellent self-healing adhesion on different substrates. Moreover, demonstrate superior tolerance including anti-freezing anti-drying, thus allowing for long-term reliability. These appealing characteristics enable accurate stable tracking human motions, well information delivery based Morse code. This study opens possibility designing tough enabled by LM composites.

Silver nanowire (Ag NW)-based elastic conductors have been considered a promising candidate for key stretchable electrodes in wearable devices. However, the weak interface interaction of Ag NWs and substrates leads to poor durability electronic For everyday usage, an additional self-healing ability is required resist scratching damage. Therefore, robust NW-based possessing stretchability, self-healing, stability are highly desirable challenging. Here, we present universal tailoring strategy that introduces thiols onto dynamically cross-linked substrate surface. The surface thiol groups strongly interact with through Ag–S bonds, forming stable conductive layer on substrate. At elevated temperatures, partially embedded buffer formed release concentrated stress. As result, conductor displays combination good conductivity, high stretchability (>1000%), efficient capability (>95%), remarkable stability. Besides, combining properties mentioned above suitable fabricating sensitive durable strain sensor against cyclic strain. presented can be versatile effective route generating other thiol-rich covalently elastomers dynamic disulfide bonds.

Self-healing materials show exceptional application potential for their high stability and longevity. However, a great challenge of the self-healing is tradeoff between mechanical robustness room temperature self-healing. In order to address this tradeoff, inspired by characteristic that small molecules living organisms self-assemble into large protein non-covalent interactions, we constructed polyurethane with highly dynamic strong hard domains composed dense hydrogen bonds π-π interactions phenylurea groups at end side chain.
