Aerogels, the lightest artificial solid materials characterized by low density and thermal conductivity, high porosity, large specific surface area, have attracted increasing interest. Aerogels exhibit single-mode insulation properties regardless of surrounding temperature. In this study, hyperelastic Kevlar nanofiber aerogels (HEKAs) are designed fabricated a slow-proton-release-modulating gelation thermoinduced crosslinking strategy. The method does not use agents endows ultralow-density (4.7 mg cm-3 ) HEKAs with conductivity (0.029 W m-1 K-1 ), porosity (99.75%), stability (550 °C), increased compression resilience (80%) fatigue resistance. Proofs concept acting as on-off switches demonstrated through experiments simulations. rapid response speed 0.73 °C s-1 , heat flux 2044 J m-2 switching ratio 7.5. Heat dissipation can be reversibly switched on/off more than fifty times owing to hyperelasticity resistance HEKAs. This study suggests route fulfill highly porous tailor on-demand.

Abstract Ice-templating technology holds great potential to construct industrial porous materials from nanometers the macroscopic scale for tailoring thermal, electronic, or acoustic transport. Herein, we describe a general ice-templating through freezing material on rotating cryogenic drum surface, crushing it, and then re-casting nanofiber slurry. Through decoupling ice nucleation growth processes, achieved columnar-equiaxed crystal transition in procedure. The highly random stacking integrating of equiaxed crystals can organize nanofibers into thousands repeating microscale units with tortuous channel topology. Owing spatially well-defined isotropic structure, obtained Al 2 O 3 ·SiO aerogels exhibit ultralow thermal conductivity, superelasticity, good damage tolerance, fatigue resistance.
