Direct synthesis of ultralight, elastic, high-temperature insulation N-doped TiO₂ ceramic nanofibrous sponges via conjugate electrospinning

Abstract

The design of three-dimensional ceramic nanofibrous materials with high-temperature insulation and flame-retardant characteristics is widely concerned due to the effectively improved mechanical properties. However, achieving pure ceramic monolith with ultra-low...

TiO2/SiO2 spiral crimped Janus fibers engineered for stretchable ceramic membranes with high-temperature resistance

“…aerogels, 10 mats, 8 membranes 15 ) and a single fiber structure ( e.g. doping, 16,17 nanograin–glass, 18,19 brick–mortar, 11 nanofiber/bead-based 15 and core–shell 20,21 ). Most existing pure ceramic nanofibrous materials possess excellent flexibility and compression properties, but the poor tensile properties make them suffer from transient structural fracture or slip under very small tensile strain, which greatly restricts their applications in extreme environments.…”
