Dielectric Parametric Study in Electrospun PLZT/PVDF Nanocomposite Membranes

Electrospun lead lanthanum zirconate titanate (PLZT)/polyvinylidene fluoride(PVDF) nanocomposite-based membranes were fabricated using a traditional electrospinning process. Scanning electron microscopy (SEM) was utilized to observe the surface morphology of the electrospun nanofiber membrane. The dielectric parameters of the nanocomposite membranes, such as permittivity, electric modulus, ac conductivity, and Impedance in the frequency range of 103 -106 Hz, were measured via an LCR measurement system. All-important electrical parameters were calculated from experimental measurements of capacitance and dissipation factor at ambient temperature. Frequency-dependent of, the above-cited parameters are presented.
