摘要
总结了经典的微粒填充复合材料体积电导率的计算公式，并针对分散相填充浓度较高的情况从串、并联电路角度进行了分析，指出这些模型各有一定的适用范围。
The electrical conductivity of particle filled polymer composite was analyzed by applying classical evaluation formulas and series — parallel circuit. It is pointed out that these models have their own range of application. Particular regulations of conductivity change of composite material with filler concentration, which were obtained from practical measurements, are explained by using the conduction current due to interfacial charge accumulation proposed by the authors.
