Comparative and verified studies of zirconium nanocomposite nanofibres by bubble spinning

Zirconia nanocomposite nanofibres were prepared from several different as‐spun fibre polymers fabricated by the bubble spinning, a novel spinning method for mass production of nanofibres. To obtain various zirconia nanocomposites, several polymers were used as zirconia powder carriers for a bubble spinning. The morphology, the thermal/mechanical property and pore‐size distribution of the obtained nanofibres were characterised and the theoretical fluid mechanics analyses were described, then a comparative and verified study drew a conclusion on the distinctions of their principle structural diagrams, resulting in different properties. Among all these nanocomposites, PAN‐based zirconia nanocomposite was found to outperform all the rest nanocomposites, which had the best thermal stability, the most uniform pore structure and the highest strength.
