Advanced aerogel fibers possess numerousadvantages amalgamating the attributes of aerogels and fibermaterials, rendering them invaluable in the realm of thermalmanagement and regulation. However, the achievement ofrobust mechanical properties and increased temperaturestability is still a major challenge for the majority of aerogelfibers. Herein, SiO_(2)-Kevlar hybrid aerogel fibers with bioniccore-shell structure were prepared by reaction spinning andweaved into fabric. Kevlar nanowires dispersion is pumpedinto a bath comprising a self-synthesized silica sol, whichfacilitates the hybridization of biphasic aerogels through thegel reaction. Precise control over the diameter (200-800 μm)and structure of the wet gel fibers was achieved throughmeticulous adjustment of the spinning solution composition and spinning parameters. Subsequent freeze-drying processfacilitates the formation of a core-shell hybrid structure, in which the SiO_(2) aerogel layer effectively encapsulate the Kevlaraerogel core fiber. Taking full advantage of the mechanical properties of the Kevlar core fiber, the resulting SiO_(2)-Kevlaraerogel fibers exhibit commendable weaving characteristics (51.8 MPa). Furthermore, SiO_(2)-Kevlar aerogel fabrics exhibitenhanced thermal insulation characteristics with a thermal conductivity of 0.037 W/(m·K). As a result of the presence ofexternal SiO_(2) aerogel layer, the overall temperature resistance performance of the SiO_(2)-Kevlar fabric reach up to 700 ℃.

Alternating current electroluminescent (ACEL) devices have become an important direction for the development of visualized smart wearable e-textiles due to their advantages of light weight, flexibility, easy integration, and convenient processing. The electrode layer is a crucial component of ACEL devices, providing the necessary electric field for the dielectric and luminescent layers, and facilitating the stable transport and recombination of electrons and holes in the luminescent layer. Herein, the structural design principles and luminescence mechanisms of ACEL are reviewed, and the newest research and remarkable results of metal-, carbon-, and ion-gel-based electrodes are introduced. This review emphasizes that optimizing the conductive pathways of electrodes, enhancing the interfacial roles of functional layers, and adjusting the thickness and microstructure of layers are crucial for developing high-brightness and stable ACEL devices. Also, increasing the electric field strength and selecting high dielectric constants are identified as key factors. On this basis, the recent progress of ACEL fibers, films, and fabrics in textiles is highlighted. Finally, the challenges and growth encountered in the development of ACEL devices are prospected, considering aspects such as voltage, luminous brightness, color, sensitivity, comfort, and large-scale processing. © 2025 The Royal Society of Chemistry.
