The potential of thermally insulated wood aerogels in energy-efficient engineering is constrained by their mechanical weakness and inadequate environmental stability. Combining minerals with offers promise for enhancing multifaceted performance. However, fabricating high-performance wood-based via organic–inorganic assembly remains challenging due to poor uniformity weak interfacial bonding. Herein, inspired diatoms, an ultrastrong flame-retardant biomimetic polymethylsilsesquioxane–wood aerogel (MSQW) fabricated combining a nanoscale heterogeneous strategy sol–gel process precisely engineer each level the hierarchy. Meanwhile, situ mineralization amorphous inorganic oligomers firmly welds interface, forming continuous homogeneous monolithic structure. resulting MSQW exhibits ultrahigh stiffness axial direction (Young's modulus 68.73 ± 3.20 MPa) withstands over 60% strain at 6.97 MPa radial direction, recovering its original shape after stress release, unique structural features. Additionally, excellent combination properties, including outstanding fire resistance ( peak heat release rate 91.13 kW/m2), hydrophobicity (water contact angle 137.3°), degradability. These advanced properties make ideal material thermal insulation harsh environments.

Abstract Metal oxide aerogels, inorganic cousins of the highly commercialized metalloid silica exhibit distinct properties specific to each type. Nevertheless, they share a common challenge with aerogels—brittleness and low mechanical strength due their particulate necklace‐like structure. In contrast, polymer aerogels often boast significantly enhanced thanks nanofibrillated networks. To enhance metal formation polymeric nanostructure is micro‐templated. This method transforms microstructure (e.g., Al 2 O 3 Cr , Fe ) into polymer‐like nanobelt Remarkably, even after removing template through calcination at 600 °C, structure remains intact. These (MNB) exceptional compressibility while retaining mesoporous As demonstration, resulting Al‐MNB aerogel can withstand compression up 80% strain without fracturing preserving its porous high surface area 228 m g −1 pore volume 0.7 cm heat treatment 1300 °C. work introduces an innovative strategy for creating distinctive microstructure, paving way novel applications unique structures performance.
