摘　　要：采用熔融共混的方法制得聚乙烯/纳米二硫化钼复合材料,研究该复合材料的电性能及其微观形貌.结果表明,当二硫化钼质量分数大于15%时,体系的电阻明显下降,复合材料的渗滤阀值为15%;二硫化钼均匀分散于聚乙烯基体中,二硫化钼导电颗粒相互接触,形成链状导电网络.The composites were prepared by melt-mixing high-density polyethylene filled with nanoscaled molybdenum disulfide, the electrical conductivity property and morphology of the composites were studied. The results showed that the volume resistivity of the composites decreased visibly as the nano-MoS2 content is above 15 wt%, the percolation threshold of the composites was 15 wt%. The nano-MoS2 particles were well-dispersed in HDPE matrix and conductive network formed when the neighboring MoS2 particles contacted.
