Abstract Reliable interfacial bonding is an essential guarantee that flexible electronics can output realistic signals, especially for underwater scenes. However, conventional self‐adhesive materials usually suffer from adhesion failure, conflict between and cohesion, as well adverse effects of isotropous residue, greatly limiting their applications in electronics. Herein, a Janus hydrophobic structural gel (HSG) with asymmetric fabricated by “grafting one twig on another” approach (in situ constructing anti‐adhesive the top gel). The layer long C18 aliphatic chains achieves reliable (interfacial toughness exceeds 80 J m −2 ) assistance high mobility polymer chains, multiple interactions, effective removal liquid. anti‐adhesion containing poly(ionic liquid) more robust due to electrostatic ion‐dipole ensuring mechanical strength integral HSG.

Biomass-based hydrogels have displayed excellent potential in flexible strain sensors due to their adequacy, biocompatibility, nontoxic and degradability. Nevertheless, inferior mechanical properties, particularly at cryogenic temperatures, impeded extensive utilization. Herein, we reported a rationally designed sensor fabricated from gelatin cellulose-derived hydrogel with superior robustness, endurance, flexibility, owing triple dynamic bond strategy (TDBS), namely the synergistic reinforcement among potent hydrogen bonds, imine sodium bonds. Beyond conventional sacrificing bonds consisting of covalent coordinate synergetic dominated by strong assisted higher strength can dissipate more energy endowing 38-fold enhancement tensile (6.4 MPa) 39-fold improvement toughness (2.9 MPa). We further demonstrated that this work as robust biodegradable exhibiting remarkable broad detection range, considerable sensitivity sensing stability. Furthermore, improved nonfreezing performance achieved incorporating salts, delivered outstanding properties under subzero conditions such -20 -4 °C. It is anticipated TDBS create diverse high-performance soft-electronics for applications human-machine interfaces, healthcare.

Abstract The development of robust adhesive, conductive, and flexible materials has garnered significant attention in the realm human‐machine interface electronic devices. Conventional preparation methods to achieve these exceptional properties rely on incorporating highly polar raw materials, multiple components, or solvents. However, overexposure functional groups inherent toxicity organic solvents often render gels non‐stick potentially biocompatible making them unsuitable for human‐contact In this study, a straightforward three‐step strategy is devised preparing responsive adhesive without complex components. Structurally conductive poly( N ‐(2‐hydroxyethyl)‐acrylamide‐co‐p‐styrene sulfonate hydrate) (PHEAA‐NaSS) are synthesized by integrating ionic hydrophilic networks with distinct solvent effects. Initially, in‐suit formed PHEAA‐NaSS activated dimethyl sulfoxide, which substantially increases intramolecular hydrogen bonding enhances matrix stretchability interfacial adhesion. Subsequently, ethanol exchange reduced impact led compact network that limited surface exposure groups, resulting nonstick, convenient storage. Finally, upon contacting water, demonstrates rehydration, favorable adhesion, biocompatibility, conductivity. proposed PHEAA‐NaSS/W can stably reliably capture joint motion electrophysiological signals. Furthermore, uncomplicated gel method also applicable other electrolyte monomers.
