FABRICATION OF PB(ZRs, TI)O, NANOFIBERS BYELECTROSPINNING

Lead zirconate titanate (PZT) / Polyvinil pyrolidone (PVP) nanofibers were spun from spinnable solution by electrospinning method. Zirconium n-propoxide, Tetraisopropyl orthotitanate and Lead acetate trihydrate were solved in Ethylene glycol monomethyl ether to obtain a precursor solution with a suitable viscosity. The obtained mats were calcined at 800 °C for 2h. The morphology and crystalline phase of PZT nanofibers were characterized using X-ray diffraction (XRD), Scanning electron microscopy (SEM) and Fourier transform infrared (FTIR). XRD spectra indicated the formation of perovskite Pb(ZrO.52, TiO.48)O3 phase at 800 °C. Fibers had diameters between 50 to 500 nm by controlling of the process parameters.
