Effect of chemical treatment on phase transition of lead zirconate nanofibers

Abstract

Lead zirconate (PZ) nanofibers were treated by the solvothermal method in the presence of dimethyl formamide (DMF) solution in order to investigate the effect of chemical treatment on phase transition of PZ nanofibers. The influences of temperature and reaction time are described. The crystal structure, phase transition and morphology of the powders were analyzed by X-ray diffraction (XRD), fourier-transform infrared spectroscopy (FT-IR), differential scanning calorimetry (DSC), and scanning electron microscopy (SEM). The results of DSC confirmed that chemical treatment with DMF could effect the AFE-PE phase transition of PZ nanofibers efficiently. Significant changes of fiber size and morphology after chemical treatment are shown by SEM images. Copyright © Taylor & Francis Group, LLC.
