摘　　要：通过对PP/PVDF共混材料的微观结构与电学性能的相关参数材料的介电研究,试验表明该合金材料具有较好的介电频率稳定性。当PP/PVDF体系的介电性能随着PVDF加入量的增加下降但不明显,而压电性能随着PP的增加而增加,在相关条件下介电常数较高。同时扫描电镜照片可以看出共混体系为两相结构,两者的相界面比较明显。Dielectric study on the microstructure and electrical properties of PP / PVDF blends of materials related parameters,tests showed that the alloy material has good dielectric frequency stability. When the dielectric properties of PP / PVDF system increases the amount of PVDF added decreased but not significantly, but with the piezoelectric properties of PP increases, under the relevant conditions of high dielectric constant. Meanwhile scanning electron micrograph can be seen as a two-phase structure blends,both obvious phase interface.
