Abstract
The technique of electrospinning was employed to fabricate uniform 1-D inorganic­organic composite nanofibers from alcoholic
solutions containing polyvinyl pyrrolidone (PVP) and suitable aqueous precursors of yttrium and zirconium ions. Upon firing and sintering
under carefully pre-selected time-temperature profiles, yttria-stabilized zirconia nanofibers retaining the original morphological features
observed in the as-spun composition were obtained. X-ray diffraction was used to identify the crystalline fate of the final product. Analytical
tools such as Raman spectroscopy and scanning electron microscopy (SEM) were employed to elucidate the pathway of ceramic phase
formation and the systematic evolution of morphological features in the spun and the processed fibers. Several millimeters long, uniform
YSZ nanofibers of high phase purity could be fabricated.
