However, conventional SiC aerogels assembled from rigid nanoparticle\u2010chain skeletons are intrinsically brittle and lack reversible deformability, limiting their use under complex service conditions. Herein, inspired by the heterogeneous trunk\u2013flower\u2010cluster architecture of kapok trees, a biomimetic flexible SiC\/SiO\n                    <jats:sub>x<\/jats:sub>\n                    microribbon aerogel (SMA) is developed via carbon\u2010felt\u2010template\u2010assisted in situ reaction growth followed by controlled thermal oxidation. The aerogel features a hierarchical porous network composed of interconnected SiC\/SiO\n                    <jats:sub>x<\/jats:sub>\n                    microribbons and SiC clusters, with an ultralow density of 0.02\u00a0g\u00a0cm\n                    <jats:sup>\u22123<\/jats:sup>\n                    and a porosity above 99%. Benefiting from the highly porous microribbon\u2013cluster framework, SMA exhibits a low thermal conductivity of 0.035\u00a0W\u00a0m\n                    <jats:sup>\u22121<\/jats:sup>\n                    \u00a0K\n                    <jats:sup>\u22121<\/jats:sup>\n                    at room temperature and robust high\u2010temperature thermal insulation under direct flame heating. Moreover, the flexible SiC\/SiO\n                    <jats:sub>x<\/jats:sub>\n                    microribbons and rigid SiC cluster nodes enable reversible bending up to 150\u00b0 and recoverable compression up to 40%. The optimized heterogeneous structure further improves impedance matching and interfacial\/dipolar polarization loss, delivering a 4.0\u00a0GHz effective absorption bandwidth at 5.0\u00a0mm. This work offers a structural strategy for flexible, lightweight, multifunctional SiC aerogels for integrated thermal and electromagnetic protection in extreme environments.\n
