摘要：

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 degrees 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 100Hz to 2MHz. 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.
