Abstract The polymer composite of electrically conducting polyaniline with polyvinylidene fluoride is prepared to study the electrical conductivity and structural modifications. The electrical conductivity studies were made by varying frequency from 100 Hz to 5 MHz at room temperature. The AC conductivity remained almost constant at lower frequencies and for higher frequencies the conductivity increased. The PAni-PVDF composite exhibited better conductivity in comparison to the pure samples. The changes in dielectric properties against frequency variations were studied and exponential reduction in dielectric loss at very low frequencies was observed. The structural and morphological studies were carried out using XRD, FTIR, and SEM.

PVDF对聚苯胺结构和传输性能影响的研究

摘要 制备了导电聚苯胺与聚偏二氟乙烯的聚合物复合材料，以研究其导电性和结构改性。电导率研究是通过在室温下从 100 Hz 到 5 MHz 的不同频率进行的。AC 电导率在较低频率下几乎保持不变，而对于较高频率，电导率增加。与纯样品相比，PAni-PVDF 复合材料表现出更好的导电性。研究了介电特性随频率变化的变化，并观察到在极低频率下介电损耗呈指数下降。使用XRD、FTIR和SEM进行结构和形态研究。
