    A three-phase PZ/CNT/PVDF nanocomposite comprising lead zirconate (PZ) nanofibers, polyvinylidene fluoride (PVDF) and a small volume fraction of carbon nanotubes (CNT) was prepared by the solvent casting technique followed by composite heating at 80°C. The PZ/CNT/PVDF composites were characterized by X-ray diffraction, FT-IR and scanning electron microscopy (SEM). The dielectric properties of the composite were studied as a function of the frequency by an LCR meter. The dielectric constant of the PZ/CNT/PVDF nanocomposite was found to be in the range of 18-61 within the measurement frequencies from 100 Hz to 2 MHz. This value is higher than the dielectric constant of the PZ/PVDF nanocomposite. The measured dielectric properties demonstrate that the addition of CNT can improve the dielectric property appearance of the composite. © 2013 Copyright Taylor and Francis Group, LLC.

    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.
