Abstract Ionic conductive gels are widely sought after for applications that require reliable ionic conduction and mechanical performance under extreme conditions, which remains a grand challenge. To address this limitation, water‐induced hydration interactions deliberately controlled within the liquid (IL)‐based (ionogels) to achieve all‐round performance. Specifically, competitive between IL, water cellulose nanofibrils (CNF) balanced preserve nanoscale morphology of CNF while avoiding its dissolution. As result, both conductivity resultant ionogel synergistically enhanced. For instance, an ultra stretchable (up 10250 ± 412% stretchability) with high toughness (21.8 0.9 MJ m −3 ) (0.70 0.06 S −1 is achieved. Furthermore, multimodal sensing functions (strain, compression, temperature, humidity) realized by assembling as skin‐like membrane. Due low volatility IL strong interaction water, maintains excellent at either ultra‐low temperature (−45 °C), (75 °C) or humidity environment (RH < 15%), demonstrating superb anti‐freezing anti‐drying Overall, simple yet versatile strategy introduced leads environmentally resilient ionogels meet requirements next‐generation electroactive devices.

Abstract As wearable sensors advance rapidly, demands for multifunctional conductive soft materials are ever higher, including high stretchability, resilience, adhesiveness and stability, simultaneously in one material, stable long‐term use. Nanocomposite hydrogels incorporating two‐dimensional (2D) nanofillers, such as MXene‐composited gels, emerge promising candidates. Yet, fulfilling all above requirements, particularly large stretchability with low hysteresis, remains a challenge, owing to the easy oxidation weak interactions of MXene nanosheets polymer chains. Herein, an interfacial engineering strategy is proposed, where tannic acid (TA) high‐density hydroxyl groups introduced encapsulate into TA@MXene nano‐motif meanwhile increase hydrogen‐bonding between network. By poly(hydroxyethyl acrylate) (PHEA) network glycerol/water binary solvent, obtained organohydrogel exhibits integrated properties (>500%) hysteresis (<3%), superior fatigue resistance (consistent over 500 cycles at 300% strain), good adhesiveness, along stability (>7 days) antifreezing abilities (−40 °C). Such organohydrogels demonstrate strain‐sensitivity thermosensitive capacities, enabling accurate reliable detection human movements, electrocardiogram signals, body temperature. This general approach stabilizing nanomaterials while effectively enhancing nanomaterial‐polymer bonding applicable synthesizing diverse high‐performance nanocomposited gels.
