Abstract Developing versatile ionoelastomers, the alternatives to hydrogels and ionogels, will boost advancement of high‐performance ionotronic devices. However, meeting requirements bio‐derivation, high toughness, stretchability, autonomous self‐healing ability, ionic conductivity, reprocessing, favorable recyclability in a single ionoelastomer remains challenging endeavor. Herein, dynamic covalent supramolecular design, lipoic acid (LA)‐based (DCIE), is proposed via melt building adaptive networks with hierarchically bonding (CAN‐HDB), wherein lithium bonds aid dissociation ions integration disulfide metathesis, bonds, binary hydrogen enhances mechanical performances, capability, recyclability. Therefore, trade‐off among versatility, successfully handled. The obtained DCIE demonstrates remarkable stretchability (1011.7%), toughness (3877 kJ m −3 ), conductivity (3.94 × 10 −4 S −1 outstanding reprocessing for 3D printing, desirable Significantly, selective ion transport endows multisensory feature capable generating continuous electrical signals high‐quality sensations towards temperature, humidity, strain. Coupled straightforward methodology, abundant availability LA HPC, as well multifunction, DCIEs present new concept advanced conductors developing soft ionotronics.

The demand for anti-icing coatings to endure extremely low temperatures is substantial. Despite the innovative pioneering research on potential of ionic liquids (ILs), development such still in its infancy. Our study investigates how matrix hydrophobicity influences mobility ILs at subzero and, consequently, their behavior. Wettability results highlight key role IL anion hydrophobicity. Dielectric spectroscopy distinguishes ion temperatures. We also investigate varying crosslink density affects by measuring water absorbency. Higher released from was confirmed presence solutions, validated with UV–vis spectroscopy, and resulted increased conductivity. Differential scanning calorimetry experimental setups were employed assess ice formation temperature, time, adhesion strength. Notably, surfaces containing exhibited a remarkable reduction temperature –23.5 ℃ achieved an exceptionally strength (∼15 kPa), attributed quasi-liquid layer (QLL). Solid-state NMR provided confirmation existence QLL interface. Ice examined against accelerated weathering, icing/de-icing cycles, as well endurance frost under freeze–thaw. findings underscore significance selecting right regards when designing subfreezing applications.

Ionic Conductive Cellulose-Based Hydrogels with Superior Long-Lasting Moisture and Antifreezing Features for Flexible Strain Sensor Applications

Biomacromolecules, Год журнала: 2024, Номер 25(2), С. 838 - 852

Опубликована: Янв. 2, 2024

Nowadays, wearable devices derived from flexible conductive hydrogels have attracted enormous attention. Nevertheless, the utilization of in practical applications under extreme conditions remains a significant challenge. Herein, series inorganic salt-ion-enhanced (HPE-LiCl) consisting hydroxyethyl cellulose, acrylate, lithium chloride, and ethylene glycol/water binary solvent were fabricated via facile one-pot method. Apart outstanding self-adhesion, high stretchability, remarkable fatigue resistance, HPE-LiCl possessed especially excellent antifreezing long-lasting moisture performances, which could maintain satisfactory flexibility electric conductivity over extended periods time, even challenging such as extremely low temperatures (as −40 °C) 80 °C). Consequently, HPE-LiCl-based sensor timely accurately monitor various human motion signals adverse environments after long-term storage. Hence, this work presents strategy for design reliable smart strain sensors, used environments.
