Deep eutectic solvent (DES)‐based eutectogels, known for their superior ionic conductivity, non‐volatility, biocompatibility, and cost‐effectiveness, have emerged as promising materials for flexible devices. However, the development of tough and stretchable eutectogels remains a significant challenge. Herein, we introduce a one‐step in‐situ phase separation strategy to fabricate tough and stretchable P(MAA‐co‐AAm)/TEAC‐EG copolymer eutectogels through random copolymerization of methacrylic acid (MAA) and acrylamide (AAm) in a tetraethylammonium chloride‐ethylene glycol (TEAC‐EG) DES. The poor compatibility of PAAm segments with TEAC‐EG DES results in the formation of a polymer‐rich phase, leading to energy dissipation during loading. Simultaneously, PMAA segments exhibiting good compatibility with DES, form a solvent‐rich phase that distributes stress and facilitates ion migration. The synergy between these two phases imparts ultratoughness and excellent conductivity to the copolymer eutectogel. The resultant copolymer eutectogel exhibits high strength (2.40 MPa), toughness (22.90 MJ m−3), and remarkable stretchability of 1340%, while demonstrating excellent self‐recovery, self‐healing abilities, and adhesive performance. Notably, its ionic conductivity reaches 1.07 mS cm−1 at 20°C, rendering these eutectogels well‐suited for applications as strain sensors in human motion detection. This study presents a facile approach to tune eutectogel microstructure and properties, thereby expanding their potential applications in high‐performance flexible electronics.

“…The development of a safe and formaldehyde-free adhesive holds immense significance in safeguarding human health and the environment. The term “biobased bonding materials” refers to naturally occurring bonding materials produced by organisms in nature, the majority of which demonstrate excellent biocompatibility and low immunogenicity . The optimization of interfacial adhesion in the hydrogel is achieved through dynamic bond interactions, which are inspired by the surface attachment mechanisms observed in mussel-inspired adhesives.…”

Adhesive hydrogel-based evaporative cooling, which necessitates no electricity input, holds promise for reducing energy consumption in thermal management. Herein, inspired by the surface attachment of mussel adhesive proteins via abundant dynamic covalent bonds and noncovalent interactions, we propose a facile strategy to fabricate a self-adhesive cooling hydrogel (Li-AA-TA-PAM) using a copolymer of acrylamide (AM) and acrylic acid (AA) as the primary framework. The monomers formed hydrogen bonds between their carboxyl and amide groups, while tannic acid (TA), rich in catechol groups, enhances the adhesion of the hydrogel through hydrogen bonding. The hydrogel demonstrated strong adhesion to various material surfaces, including plastic, ceramic, glass, and metal. Even under high-speed rotation, it still maintains robust adhesion. The adhesion strength of the Li-AA-TA-PAM hydrogel to aluminum foil reached an impressive value of 296.875 kPa. Interestingly, the excellent contact caused by robust adhesion accelerates heat transfer, resulting in a rapid cooling performance, which mimics the perspiration of mammals. Lithium bromide (LiBr) with hydroactively sorptive sites is introduced to enhance sorption kinetics, thereby extending the effective cooling period. Consequently, the operation temperature of commercial polycrystalline silicon solar cells was reduced by 16 °C under an illumination of 1 kW m −2 , and the corresponding efficiency of energy conversion was increased by 1.14%, thereby enhancing the output properties and life span of solar cells. The strategy demonstrates the potential for refrigeration applications using viscous gels.
