摘要
介绍了低密度聚乙烯（聚苯乙烯）／聚吡咯复合材料的导电特性。发现复合材料的导电率和聚吡咯含量的关系可用“渗流理论”来描述，复合材料制备工艺强烈地影响其微观结构从而影响渗流门槛值。讨论了复合材料导电率的温度依赖性行为和结构的关系。
Results of measurements of the electrical conductivity of low density polyethylene (polystyrene)polypyrrole composites are reported. It is observed that the electrical conductivity of the composite versus concentration fellows the law predicted by the percolation theory. It is shown how the fabrication procedures influence the homogeneity of the composite at the microscopic scale and thus the percolation threshold. The relationship between the temperature dependence of the conductivity and structure of the composite is also discussed.
