Published: April 2, 2024

Hydrogels are soft–wet materials with a hydrophilic three-dimensional network structure offering controllable stretchability, conductivity, and biocompatibility. However, traditional conductive hydrogels only operate in mild environments exhibit poor environmental tolerance due to their high water content network, which result undesirable swelling, susceptibility freezing at sub-zero temperatures, structural dehydration through evaporation. The application range of is significantly restricted by these limitations. Therefore, developing environmentally tolerant (ETCHs) crucial increasing the scope materials. In this review, we summarize recent strategies for designing multifunctional that possess anti-freezing, anti-drying, anti-swelling properties. Furthermore, briefly introduce some applications ETCHs, including wearable sensors, bioelectrodes, soft robots, wound dressings. current development status different types ETCHs limitations analyzed further discuss future research directions prospects.

Application of supramolecular hydrogel in supercapacitors: Opportunities and challenges

Aggregate, Journal Year: 2024, Volume and Issue: 5(5)

Published: May 15, 2024

Abstract Supercapacitors (SCs) are studied and used in various fields due to their high power density, fast charging/discharging rate, as well long cycle life. Compared other traditional electrode electrolyte materials, supramolecular hydrogels have great advantages the application of SCs excellent properties. Unlike covalent bonds, systems assembled through dynamic reversible including host–guest interactions, ion electrostatic hydrogen bonding, coordination etc. The resulting show some special functions, such stretching, compression, adhesion, self‐healing, stimulus responsiveness, etc., making them strong candidates for next generation energy storage devices. This paper reviews representative progress electrodes, electrolytes, based on hydrogels. Besides, properties hydrogels, conductivity, extensibility, compressibility elasticity, frost resistance, flexibility, also reviewed highlight key role hydrogel materials SCs.

Lignin-Based Antioxidant Hydrogel Patch for the Management of Atopic Dermatitis by Mitigating Oxidative Stress in the Skin

ACS Applied Materials & Interfaces, Journal Year: 2024, Volume and Issue: 16(26), P. 33135 - 33148

Published: June 20, 2024

Atopic dermatitis (AD), a chronic skin condition characterized by itching, redness, and inflammation, is closely associated with heightened levels of endogenous reactive oxygen species (ROS) in the skin. ROS can contribute to onset progression AD through oxidative stress, which leads release proinflammatory cytokines, T-cell differentiation, exacerbation symptoms. In this study, we aim develop therapeutic antioxidant hydrogel patch for potential treatment using lignin, biomass waste material. Lignin contains polyphenol groups that enable it scavenge exhibit properties. The lignin patches, possessing optimized mechanical properties control cross-linker ratio, demonstrated high ROS-scavenging capabilities. Furthermore, excellent biocompatibility skin, exhibiting beneficial protecting human keratinocytes under conditions. When applied an mouse model, effectively reduced epidermal thickness inflamed regions, decreased mast cell infiltration, regulated inflammatory cytokine levels. These findings collectively suggest serves as managing modulating stress its ability.
