More importantly, as the nano-ZrO 2 mass ratio increased, temperature exerted less influence on the viscosity of the ZrO 2/SiO 2-STF system diminished, but still had a significant influence on the shear thickening effect. The hollow magnetic porous zirconia fibers have a BET specific surface area of 34.70 m 2 g 1 and a pore volume of 0.18 cm 3 g 1. The rheological testing results showed that the ZrO 2/SiO 2-STF system produced a considerable shear thickening effect when the nano-ZrO 2 mass ratio was 12%, the critical shear rate of the system was relatively small and the peak value of apparent viscosity was relatively large.

By adding magnetic particles to the inner electrospinning precursor solution, magnetic nanoparticles were conveniently assembled into the hollow ZrO 2 fibers. The presence of ZrO 2 and their interaction with the SiO 2 nanoparticles in the STF were analyzed using scanning electron microscope (SEM), Energy dispersive spectroscopy (EDS) and x-ray diffractometer (XRD). Nano-ZrO 2/SiO 2-STF of different concentrations (9.0-20.0 wt%) were prepared via an ultrasonication and mechanical stirring technique. For the synthesis of PdPt-ZrO 2 /MWCNT hybrids, 0.4 g of MWCNT was first reached 50 ml using deionized water and placed in an ultrasonic bath for 30 minutes. The influence of the ZrO 2 mass ratio on the sensitivity of nano-ZrO 2/SiO 2-STF to temperature was further discussed. In this study, the rheological characteristic of shear thickening fluid (STF) with various mass ratios of zirconium dioxide (ZrO 2) to silicon dioxide (SiO 2) was investigated.
