Here, we solve this problem by constructing a flexible, nacre\u2010mimetic mullite nanofiber aerogel paper through a self\u2010templated electrospinning strategy. In this design, functionalized mica nanosheets serve as dielectric barriers uniformly embedded within a\u00a0mullite nanofiber framework, forming a brick\u2010and\u2010mortar architecture. This structure not only creates an extended tortuous path to suppress electron avalanche breakdown but also establishes a double\u2010network bandgap that inhibits charge transport and segmental chain motion. The aerogel paper thus achieves an exceptional electrical resistivity of 6.5 \u00d7 10\n                    <jats:sup>14<\/jats:sup>\n                    \u03a9\u00b7cm while maintaining stable dielectric performance above 500\u00b0C. Moreover, by grafting low\u2010surface\u2010energy ormosil directly into the precursor sol, we circumvent the pore\u2010clogging and hydration issues inherent to post\u2010synthesis treatments, endowing the aerogel paper with super\u2010hydrophobicity. This combination of ultralight weight, high\u2010temperature dielectric stability, and environmental durability represents a paradigm shift in material design for next\u2010generation miniaturized high\u2010power electronics.\n
