Nanofibrous core/nanoporous sheath structured ultra–flexible ceramic aerogels for thermal superinsulation

at 26 °C and remains stable at working temperatures exceeding 1300 °C. Ultimately, proposed CSCA constitutes a fundamentally new approach in structure design to resolving the formidable mechanical-thermal tradeoff of aerogels, and it offers promising material configuration for further advancements in thermal superinsulation.
