Abstract We report the synthesis and characterization of Ag/Au-MnO2 nanoparticles dispersed PVDF nanocomposites having high dielectric properties. The Ag/Au-MnO2 nanoparticles are synthesized by hydrothermal method, and were characterized by XRD, SEM and EDAX spectroscopic techniques. The prepared nanocomposites of Ag-MnO2 nanoparticles and Au-MnO2 nanoparticles dispersed PVDF are characterized using XRD, SEM, TGA, DTA and Electrical properties. The Ag/Au-MnO2 incorporated PVDF nanocomposite shows high dielectric constant, electrical conductivity, and reduction in resistivity when compared to neat PVDF. The high dielectric constant was observed for 3%Ag/MnO2 dispersed PVDF with a value of 3.5 × 10−4 and 2% Au/MnO2 dispersed PVDF showed 1.0 × 10−9 at 1 MHz.

Ag/Au-MnO2纳米结构嵌入聚偏二氟乙烯高K纳米复合材料的合成与表征

摘要 我们报告了具有高介电性能的 Ag/Au-MnO2 纳米颗粒分散 PVDF 纳米复合材料的合成和表征。Ag/Au-MnO2纳米颗粒是通过水热法合成的，并通过XRD、SEM和EDAX光谱技术进行了表征。使用XRD、SEM、TGA、DTA和电学性质对制备的Ag-MnO2纳米颗粒和Au-MnO2纳米颗粒分散PVDF的纳米复合材料进行表征。与纯 PVDF 相比，掺入 Ag/Au-MnO2 的 PVDF 纳米复合材料显示出高介电常数、导电性和电阻率降低。观察到 3% Ag/MnO2 分散 PVDF 的高介电常数为 3.5 × 10-4，2% Au/MnO2 分散 PVDF 在 1 MHz 下显示为 1.0 × 10-9。
