| 摘 要： | 研究了掺Al或Ag微粉的聚丙烯（PE）基和聚二氯乙烯（PVDF）基复合材料的导电开关特性，发现在某一电场阈值（对应开关电压阈值Vk）附近，复合材料的电导率随外电场的变化而发生大幅度变化，还研究了掺入金属微粉的种类、体积比及颗粒度对Vk的影响，验证了量子隧道效应是复合材料导电开关特性的主要机理。

| Abstract: | This paper studied the characteristics of switching effect in Ag - PE, Al - PE, Ag - PVDF and Al -PVDFcomposites. Found the conductivity has Changed greatly while electric field changed near the threshold value (correlative threshold value of switching voltage is VK). And studied that the VK is influnced by the kinds, volume ratio andparticle size of mixing metal. Verified the mechanism of switching effect in Composite is quantum tunnel effect. |
