Given extremely high porosity, aerogels have demonstrated remarkable advantages in serving as thermal insulation and wave-transparent materials. Unfortunately, their practical applications are greatly confined by inherent fragility. The recent emergence of polymer presents an ideal platform for the development flexible aerogel films. However, additional cross-linking agents necessitated constructing a robust structure, complicating production process. Herein, we report film based on meta-aramid composites, inspired porous structure penguin feathers. intermolecular hydrogen bonds function natural agents. Their disruption results dissolution fibers, while reconstruction facilitates localized rearrangement chains during sol-gel process, generating closed nanopores. Furthermore, fluorinated hollow glass microspheres filled, compressing nanopores situated near interface to 75-150 nm. This meets critical threshold required Knudsen effect, decreasing conductivity levels below that ambient air. At optimized doping ratio 3 wt%, is 21.6 mW m-1 K-1, achieving low dielectric constant 1.43. Simultaneously, films exhibit enhanced mechanical properties, also show benefits hydrophobicity, colorability, ultralightness, flame retardancy, making themselves multifunctional materials suitable applications.
