Deep eutectic solvent (DES)-based eutectogels show significant promise for flexible sensors due to their high ionic conductivity, non-volatility, biocompatibility, and cost-effectiveness. However, achieving tough stretchable is challenging, as the highly polar DES tends screen noncovalent bonds, such hydrogen between polymer chains, limiting mechanical strength. In this work, issue addressed by leveraging limited solubility of zwitterionic polymers in a specific induce phase separation, promoting dipole-dipole interactions chains. These improve energy dissipation under stress, allowing creation P(MAA-co-VIPS)/TBAC-EG through copolymerization-induced separation approach. Methacrylic acid (MAA) sulfobetaine vinylimidazole (VIPS) are copolymerized within tetrabutylammonium chloride-ethylene glycol (TBAC-EG) DES, resulting bicontinuous network. The structure consists PVIPS-rich that enhances toughness via interactions, PMAA solvent-rich enables stretchability. eutectogel demonstrates excellent properties, including strength 1.76 MPa, 16.61 MJ m⁻

Abstract Eutectogels with inherent ionic conductivity, mechanical flexibility, environment resistance, and cost‐effectiveness have garnered considerable attention for the development of wearable devices. However, existing eutectogels rarely achieve a balance between strength, strain, resilience, which are critical indicators reliability in flexible electronics. Herein, poly(sodium styrenesulfonate) (PSS)‐modified gold nanoparticles (AuNPs) eutectic solvents synthesized, PSS‐AuNP reinforced polyacrylic acid/polyvinylpyrrolidone (SAu‐PAA/PVP) eutectogel is successfully prepared. Through coordination AuNPs PAA/PVP polymer chains, SAu‐PAA/PVP exhibits significantly enhanced tensile strain (946%), strength (3.50 MPa), resilience (85.3%). The high‐performance was demonstrated as sensor sensitive to temperature, provided near‐infrared sensing capabilities. Furthermore, inherits benefits ES, including anti‐drying anti‐freezing properties (−77 °C). Moreover, microstructured using simple molding method, resulting hierarchical pyramid functions dielectric layer pressure sensor. This high sensitivity (37.11 kPa −1 ), low detection limit (1 Pa), fast response rate (36/54 ms), excellent reproducibility over 5000 cycles, making them reliable durable detecting small vibrations, potential applications precision machinery, aerospace, buildings.

Abstract Eutectogels are emerging as the next‐generation stretchable electronics due to their superior ionic conductivity, non‐volatility, and cost‐effectiveness. Nevertheless, most eutectogels suffer from weak mechanical strength toughness pronounced hygroscopicity. Herein, a strategy is proposed fabricate phase‐separated with dual channels (PSDIC‐gel), which exhibit exceptional integrative properties, especially water resistance. By blending hydrophilic/hydrophobic polymerizable deep eutectic solvents, spontaneously form via polymerization‐induced phase separation. The hydrophilic poly(acrylic acid) (PAA) containing Li + ‐channels, rich in hydrogen bonding ion‐dipole interactions, provides conductivity. hydrophobic poly(hexafluorobutyl acrylate) (PHFBA) incorporating cholinium cation (Ch ) enhances toughness, Adjusting ratio yields microphase‐separated transparent eutectogel high tensile (6.03 MPa), (16.18 MJ m −3 ), excellent conductivity (1.6 × 10 S −1 strong substrate adhesion, rapid room‐temperature self‐healing. Solid‐state NMR reveals conductive mechanism structure featuring PSDIC‐gels, advancing understanding of complex interactions at atomic level. PSDIC‐gel enables flexible triboelectric nanogenerator for accurate real‐time self‐powered human motion sensing. This work advances design through structure‐property engineering, offering universal reconcile robustness, environmental suitability, wearable electronics.
