Nano-scaled core-sheath ceramic aerogel demonstrates favorable thermomechanical properties/ thermal superinsulation performance

https://www.eurekalert.org/news-releases/1101496

"ceramic aerogels typically highly brittle, overcome using unitary structured dual-phase nanofibrous core for ultra- flexible deformation/ nanoporous sheath for thermal superinsulation... introduces numerous nanopores suppressing air conduction, resulting in a κ less than 24 mW·m−1·K−1... enables all nanoporous aerogels to be orderly assembled onto fibers' surface, increasing stability... mechanical flexibility with compressive strain up to 80%, fracture strain up to 21.9%, bending strain up to 100%... up to 1,300°C working temperature"
