Ion-confined ice template-driven advanced aramid nanofiber aerogels for efficient adiabatic applications in harsh environments

). Moreover, SN aerogels display integrated properties of mechanical elasticity and extreme temperature durability (80% compressible strain from -196 to 400 °C), fire resistance, and recyclability, ensuring the strong adaptive capacity in harsh environments and the friendly closed-loop re-processibility. This study provides a versatile strategy for regulating ice-crystal growth in nanofiber aerogels and opens new opportunities for developing advanced ultralow-thermal-conductivity adiabatic materials.
