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.
