摘要
SiC fibers are widely used in aerospace, military and nucleus fusion. Herein, SiC ultrathin fibers, hierarchical TiO2/SiC and SnO2/SiC fibers were successfully fabricated via electrospinning combined with polymer-derived ceramics route and hydrothermal method. The compositions and microstructures of these SiC-based ultrathin fibers were characterized in detail. The SiC ultrathin fibers exhibited a high specific extinction coefficient of 160 m2 kg-1. The hierarchical TiO2/SiC fibers exhibited high sensitivity (16.9) and selectivity toward acetone, while the hierarchical SnO2/SiC fibers presented high sensitivity (23.5) toward ethanol. These SiC-based ultrathin fibers were anticipated to have great potentials in the application of gas sensors and reinforcements for high-temperature insulations. © 2017 The American Ceramic Society.
