Abstract The high-density polyethylene (HDPE) conductive composites filled separately with carbon fibers (CFs), ethylene-vinyl acetate copolymer (EVA), and three kinds of carbon blacks (CBs) (including different diameter, BET specific area, and DBP value) were prepared, to investigate the influence of the property, size, and content of the conductive fillers on the nonlinear voltage–current characteristics of the HDPE conductive composites. The results showed that the relationship between the electric current density and the electric field intensity of the three HDPE/CB composites including the HDPE/CF composites, the HDPE/CB/CF composites, and the HDPE/EVA/CB composites was nonlinear. The nonlinear conductivity index of the HDPE/CF composites was kept a low level comparing to the HDPE/CB composites, the HDPE/CB/CF composites, and the HDPE/EVA/CB composites. Moreover, the nonlinear conductive behavior mechanisms were discussed.

高密度聚乙烯导电复合材料的电压-电流特性

摘要 分别填充碳纤维(CFs)、乙烯-醋酸乙烯共聚物(EVA)和三种炭黑(CBs)(包括不同直径、BET比表面积和DBP值)的高密度聚乙烯(HDPE)导电复合材料。 ),研究导电填料的性质、尺寸和含量对 HDPE 导电复合材料的非线性电压-电流特性的影响。结果表明,HDPE/CF复合材料、HDPE/CB/CF复合材料和HDPE/EVA/CB复合材料三种HDPE/CB复合材料的电流密度与电场强度之间的关系是非线性的。与 HDPE/CB 复合材料、HDPE/CB/CF 复合材料相比,HDPE/CF 复合材料的非线性电导率指数保持在较低水平,和 HDPE/EVA/CB 复合材料。此外,还讨论了非线性导电行为机制。
