Item type:Publication, Synthesis and phase evolution of electrospun antiferroelectric lead zirconate (PbZrO3) nanofibers(2012-08-01); ; ; Lead zirconate (PbZrO<inf>3</inf>; PZO) fibers were synthesized by the electrospinning method using a solution that contained 5 wt% poly(ethylene oxide) (PEO) in ethanol and a sol-gel solution of PZO. Some parameters varied, for example, the ratio between PEO and PZO, concentrations of the precursor solution, flow rate, and calcination temperature. The as-spun and calcined PZO/PEO composite fibers were characterized by TG-DTA, X-ray diffraction, FT-IR, SEM and TEM. PZO fibers were obtained successfully with a well-developed perovskite structure after as-spun PZO/PEO composite fibers were calcined using the PZO/PEO volume ratio of 10:3 at a PZO concentration of 1.0 M at 650 °C for 4 h. Stable nanofibers were produced with an average diameter of 300 ± 64 nm. Additionally, the PZO fibers showed a Curie temperature that rose by nearly 13 °C, when comparing with a normal PZO particle. © 2012 Elsevier B.V.

Item type:Publication, Preparation and dielectric properties of 3-3 lead zirconate/polyvinylidene fluoride nanocomposite(2013-01-01); ; Composites made of electroactive ceramics and a ferroelectric polymer are very attractive for applications since they exhibit good piezoelectric and pyroelectric properties, low densities and their properties can be tailored to various requirements. Here, we reported the preparation and dielectric properties of 3-3 PZ/PVDF nanocomposites by infusion of polyvinylidenedifluoride (PVDF) into the PZ nanofiber mat followed by heating of the composite at 80°C. The 3-3 PZ/PVDF composites were characterized by X-ray diffraction, FT-IR, SEM and LCR meter. The dielectric constant of the PZ/PVDF nanocomposite are relatively stable in the range of 21.98-18.21 within the measurement frequencies from 100 Hz to 2 MHz. This value is higher than the dielectric constant of the polyvinylidene fluoride. Moreover, the dielectric loss of the composite is below 0.09 at low frequencies. © 2013 Copyright Taylor and Francis Group, LLC. - Some of the metrics are blocked by yourconsent settings
