摘要: Pb(Zr0.52Ti0.48)O3 (PZT) nanofibers with diameters of 150–200 nm are prepared via electrospinning and used as dielectric fillers in poly(vinylidene fluoride) (PVDF)-based composite films. Highly flexible polymer films fabricated a solution cast method. Enhanced constants obtained at low volume fraction PZT nanofibers. The orientation perpendicular to the external electric field gives rise improved breakdown strength. A subsequent uniaxial stretching leads higher crystallinity strength composites, which is favorable for polarization nanocomposites fields. ferroelectric properties, i.e., saturated remnant polarization, these high piezoelectric coefficient (d33) ∼87.4 pm V−1 also achieved filled only 2.4 vol% results show that PZT/PVDF have potential applications sensors, even actuators.
