Silicon carbide (SiC) aerogels with high porosity and excellent thermal stability are a promising thermal insulation and adsorption material. However, the poor mechanical properties of SiC aerogels greatly limit its practical application. Herein, inspired by flexible palm bark, for the first time, we report a novel method called “bioinspired link assembly” (BLA) to fabricate bioinspired SiC aerogels (BSA) with significant layered structure. The layered structure and elastic links are in situ constructed in bioinspired link assembly process. The BLA method optimizes structure of the BSA by regulate monolayer dimensions. Owing to the elastic links between the layered structures, the BSA can be bent 180°. Moreover, the BSA shows super-elasticity (elastic deformation up to 70 %) and fatigue resistance (100000 compressions). Benefiting from layered structure, the BSA exhibits an ultralow thermal conductivity (0.027 W m⁻¹ K⁻¹). In addition, BSA shows excellent absorption capacities (weight gain about 44 ∼ 72 times) for organic solvents. Therefore, the excellent comprehensive properties make BSA have broad application prospects in the fields of high temperature thermal insulation and oil pollution treatment.

碳化硅（SiC）气凝胶具有高孔隙率和优异的热稳定性，是一种很有前途的绝热和吸附材料。然而，碳化硅气凝胶较差的力学性能极大地限制了其实际应用。在此，受柔性棕榈树皮的启发，我们首次报告了一种称为“仿生链接组装”(BLA) 的新方法，用于制造具有显着层状结构的仿生 SiC 气凝胶 (BSA)。分层结构和弹性链接就位在 bioinspired 链接组装过程中构建。BLA 方法通过调节单层尺寸来优化 BSA 的结构。由于分层结构之间的弹性连接，BSA 可以弯曲 180°。此外，BSA 显示出超弹性（弹性变形高达 70%）和抗疲劳性（100000 次压缩）。受益于层状结构，BSA 表现出超低的热导率 (0.027 W m ^-1 K ^-1 )。此外，BSA 对有机溶剂表现出优异的吸收能力（增重约 44 ∼ 72 倍）。因此，优异的综合性能使得BSA在高温绝热、油污治理等领域具有广阔的应用前景。
