Abstract

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.
静电纺PLZT/PVDF纳米复合膜的介电参数研究
采用传统静电纺丝工艺制备了锆钛酸铅镧/聚偏氟乙烯(PVDF)纳米复合膜。利用扫描电子显微镜(SEM)观察了静电纺纳米纤维膜的表面形貌。利用LCR测量系统测量了纳米复合膜在103 ~ 106 Hz范围内的介电常数、电模量、交流电导率和阻抗等介电参数。所有重要的电学参数都是根据环境温度下电容和耗散系数的实验测量来计算的。给出了上述参数的频率依赖性。
