Summary:Title screen
Ceramic nanofiber materials have significant potential for thermal insulation applications. However, their tensile strength is often limited due to the random arrangement of nanofibers, which makes them prone to deformation or fracture under practical conditions. This research aims to develop highly oriented mullite nanofiber membranes with enhanced tensile strength, which were fabricated by controlling the evaporation rate of an inorganic sol and the directed collection of nanofibers. The results show that the tensile strength of the obtained membranes can reach up to 7 MPa, which is significantly higher than that of conventional unoriented membranes. Furthermore, when combined with a mullite nanofiber sponge to a thickness of 1.5 cm, the composite demonstrates excellent thermal insulation, maintaining a backside temperature of only 219 °C when exposed to a 1200 °C flame. The unique design of highly oriented mullite nanofiber membranes makes them widely applicable as support materials or substrates in high-temperature industrial devices, as well as in joint components of personal protective equipment and high temperature thermal protection systems in the aerospace industry
