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 ℃.

To achieve the scalable production of high-performance melamine-based flame retardant nanofibers, solution blowing spinning technology was employed into the continuous spinning of melamine(MA)@polyacrylonitrile(PAN) composite fibers. Propelled by the compressed air current, spinnable MA@PAN solutions can be shaped into nanofiber with a high flow rate over 50 m L/h. Among different melamine-based materials,melamine phosphate(MPP) exhibited excellent solubility in the solution, exceeding 30 wt%, ensuring that the MPP@PAN nanofiber products demonstrated exceptionally robust flame-retardant performance. Furthermore,through fiber textile needle punching technology, loose fiber sponge can be organized into enhanced fiber blankets. These MPP@PAN nanofiber products exhibited outstanding flame retardant and thermal insulation properties, rendering them pivotal as the flame-retardant materials in extreme environments.

Achieving large-scale production of high-performance mullite ceramic nanofibers posed a formidable ***, an air heating-solution blow spinning technique was designed for the mass fabrication of mullite nanofibers at high speeds, ranging from 6 to 60 ml/h. Spinnable aqueous Al–Si solution systems, employing various aluminum sources, were systematically investigated. The optimization of the solution blow spinning apparatus involved the incorporation of a hot air blow device capable of dispensing streams of hot, dry air. Comprehensive investigations were conducted to examine the impact of variables such as spinning solution viscosity, spinning rate, and spinning distance on the resulting mullite fiber diameter and morphology. Following sintering at 1200°C, mullite fiber cotton was successfully synthesized, exhibiting diameters spanning from 500 nm to 5 μm. These mullite nanofiber cotton demonstrated exceptional attributes, including robust temperature stability(up to 1300°C), remarkable thermal insulation properties and superior filtration efficiency.

Elastic zirconium-based ceramic fiber products have gain particular interest due to their exceptional hightemperature resistant performance. Nonetheless, commercial high-performance Zr-based fibers are still difficult to acquire which hinders its widely application in thermal insulation scenes. Herein, large-scale fabrication of various Zr-based（ZrO2, ZrSiO4） ceramic fibers were achieved through solution blow spinning technology, which was endowed with merits such as cost-effectiveness, high production efficiency, reduced energy consumption, and exceptional product quality. Through high-temperature sintering to 1000°C, blow spun organic fibers can be converted into Zr-based ceramic fibers with diameters ranging from 0.5 to 2 μm. Optimizing the crystalline structure of these fibers through high-temperature pyrolysis process enhanced their thermal resistance. Additionally, through introducing polysiloxane as the Si source, ZrSiO4fibers can be synthesized with markedly improved mechanical properties and high-temperature resistance. These blow-spun Zr-based fiber sponges exhibit advantageous internal pore structures, high-temperature elasticity and thermal insulation performance.
