Tin Oxide Nanofiber and 3D Sponge Structure by Blow Spinning

Abstract

SnO2 nanofibers show wide applications in many advancing areas, such as gas sensors and semiconductors. The traditional methods of fabricating SnO2 nanofibers include electrospinning, hydrothermal synthesis etc. In this work, SnO2 nanofibers were prepared by blow spinning, which is a convenient and high-efficient method. Meanwhile, a 3D sponge nanofiber network can be produced by accumulating fibers in a novel collector. While traditional SnO2 nanofibers obtained from previous work show high brittleness, the SnO2 nanofiber sponge has good resilience against external compression and can recover to its original shape.
