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.

Abstract Polymer‐based electrostatic capacitors are important energy storage components in power systems, yet they suffer from low breakdown strength due to the vigorous movement of molecular chains at elevated temperatures. Herein, hollow‐structured alumina nanotubes prepared by an ion exchange method and introduced into polyetherimide films. In this design, act as equivalent crosslinking points which can restrain polymer that pass through nanotubes. Meanwhile, wide bandgap trap scatter charges further contribute enhancement strength. Accordingly, when merely 0.3 wt.% incorporated film, a significantly boosted 679.54 MV m −1 , is 143.80% pure polyetherimide, achieved 200 °C. Consequently, ultrahigh density 6.54 J cm −3 (efficiency > 90%), reaches 641.18% pristine (1.02 ), obtained This work provides innovative strategy, i.e., constructing points, greatly enhance high‐temperature pulsed performances dielectrics.
