Facile Preparation of Continuous and Porous Polyimide Aerogel Fibers for Multifunctional Applications

), which render the woven PAF fabrics with excellent thermal insulation properties within a wide temperature range (-190 to 320 °C) and potential applications for thermal insulation under harsh environments. Additionally, a series of functionalized aerogel fibers or their fabrics based on PAFs, including phase-change fabrics with a thermoregulation function and electromagnetic shielding (EMI) textiles with a high EMI SE value, have been successfully fabricated for expanding their potential applications. Overall, this novel aerogel fiber sheds light on a promising direction for developing the next generation of high-performance thermal insulation and multifunctional fibers and textiles.
