Conductive eutectogels have emerged as candidates for constructing functional flexible electronics they are free from the constraints posed by inherent defects associated with solvents and feeble network structures. Nevertheless, developing a facile, environmentally friendly, rapid polymerization strategy construction of conductive integrated multifunctionality is still immensely challenging. Herein, eutectogel fabricated through one-step dialdehyde xylan (DAX)/liquid metal (LM)-initiated deep eutectic solvent. DAX acts stabilizer preparation LM nanodroplets plays crucial role in facilitating ultrafast gelation (less than 2 min) virtue its reducing groups. Notably, this fabrication obviates use toxic chemical initiators cross-linkers. The resultant exhibit extremely high stretchability (2860%), desirable self-healing ability, conductivity (0.72 S m–1), biocompatibility, excellent environmental stability, exceptional responsiveness to tensile strain (GF = 4.08) temperature (TCR 5.35% K–1). Benefiting these features, serve multifunctional sensors human motion recognition monitoring. Furthermore, serves pliable electrode assembly triboelectric nanogenerator (TENG), designed harvest mechanical energy, convert it into stable electrical outputs, enable self-powered sensing. This study offers an approach fabricating eutectogels, making step closer development intelligent electronics.

The development of transparent wearable devices capable self-healing and efficient fog removal is great significance. In this study, we have realized the fabrication a composite film exhibiting remarkable transparency along with light-triggered healing defogging capabilities. This was achieved by integrating plasmonic silver nanoparticle (AgNPs) embedded covalent–organic framework (COF) nanosheets, denoted as AgNPs/CONs, into waterborne elastic polyurethane (PU) matrix. Due to synergistic effect between AgNPs high properties COF nanosheets excellent photothermal characteristics, resulting film, even an ultralow loading AgNPs/CONs (0.15 wt %), demonstrate rapid temperature increase 80 °C upon exposure 500 mW cm–2 near-infrared (NIR) light irradiation for 12 s. Simultaneously, it maintains optical transmittance 96.2% at thin thickness 20 μm extremely low (0.08 %). localized elevation effectively eliminates surface promotes mechanical damage within achieving efficiency exceeding 98%. Our findings represent significant advancement in design photothermally active materials based on COFs, opening up new prospects next-generation electronic applications.
