Chemical Science, Journal Year: 2024, Volume and Issue: unknown

Published: Jan. 1, 2024

Flexible strain sensors are broadly investigated in electronic skins and human-machine interaction due to their light weight, high sensitivity, wide sensing range. Hydrogels with unique three-dimensional network structures widely used flexible for exceptional flexibility adaptability mechanical deformation. However, hydrogels often suffer from damage, hardening, collapse under harsh conditions, such as extreme temperatures humidity levels, which lead sensor performance degradation or even failure. In addition, the failure mechanism environments remains unclear. this review, of hydrogel various conditions examined. Subsequently, strategies towards environmental tolerance summarized. Finally, current challenges discussed, along potential directions future development applications.

Antifreezing, Water Retention, and High‐Stretch Ionic Conductive Hydrogels for Winter Motion Sensing

Journal of Applied Polymer Science, Journal Year: 2025, Volume and Issue: unknown

Published: April 8, 2025

ABSTRACT Conductive hydrogels are promising for flexible electronic device applications, where strain change is converted to electrical signal responses. However, most reported conductive typically frozen around 0°C and dried out limiting their potential applications. Herein, a highly stretchable ionic hydrogel (ICH) with antifreezing water retention properties was prepared using natural polymer‐based (sodium alginate‐co‐polyacrylamide) as the matrix material. By introducing hydrated salt CaCl 2 ethylene glycol via solvent displacement method, ICH exhibits high conductivity (0.91S/m at 20°C), transparency (95%), (−43°C). Moreover, optimized achieves satisfactory sensitivity toward tension (gauge factor = 2.58 100% strain). Interestingly, real‐time sensing system wearable motion based on resulting well developed by integrating wireless transmission platform. It anticipated that such an will significantly broaden opportunities sensor

Biomimetic Xanthium Strumarium Inspired Superhydrophobic Anti‐/De‐Icing Films with Near‐Infrared Light‐Induced Self‐Healing

Small, Journal Year: 2025, Volume and Issue: unknown

Published: May 7, 2025

Abstract Superhydrophobic surfaces are susceptible to structural deformation and damage during use, which significantly impacts their long‐term stability performance in anti‐/de‐icing applications. To address this challenge, a biomimetic superhydrophobic polyurethane film inspired by Xanthium strumarium (PBXS) is proposed. This not only delivers efficient but also demonstrates exceptional durability. Even when the surface structure undergoes or complete fracture, it can quickly self‐heal under near‐infrared light, restoring its original properties. The results show that, due micron spine array photothermal effect, PBXS delay droplet freezing at low temperatures (−10 °C, 2052 s) enable rapid de‐icing (1 sun, 187 s). Moreover, incorporating shape‐memory properties of thermoplastic self‐healing capability, effectively addresses issues related (after ten deformation‐healing cycles, maintains water contact angle 157 ± 1° rolling 15.4 1°) material rupture fracture‐healing retains 152 16.1 1°). innovative approach enhances films shows significant potential for applications road transportation, power transmission lines, other fields.
