Lead zirconate titanate (PZT)/poly vinyl acetate (PVAc) green nanofibers were spun by electrospinning PZT/PVAc mixture. The acidification (acetic acid) effect of PZT/PVAc Solution oil the morphology of PZT ceramic fibers calcined at various temperatures was investigated by scanning electron microscopy (SEM), transmission electron microscopy (TEM), Fourier transform infrared (FTIR) and X-ray diffraction (XRD). The PZT ceramic fibers processed with acetic acid (CH3COOH) turned out to be thinner and more compact, compared to the fiber without it. It was also evident that there was an optimal concentration of acetic acid for the dense PZT nanofiber. In addition. FTIR and XRD revealed that the complete perovskite formation was achieved by the calcination between 650 degrees C and 700 degrees C. (c) 2009 Elsevier B.V. All rights reserved.
