摘要

摘要研究发现，在渗流阈值区域，根据一种或另一种传导机制的主导地位，以乙烯-醋酸乙烯酯为基体的聚合物复合材料的比体积电阻率 ρ(T) 的温度依赖性会发生显著变化。随着 CB 含量的增加，相对电阻率ρ(T)max/ρ20 的最大值随温度的变化降低了几个数量级。基质大分子的过氧化物交联导致电阻率随温度变化的性质发生变化。

The Influence of Carbon Black Content on Temperature Dependences of Electrical Conductivity of Polymer Composite

Abstract

It was found that in the region of the percolation threshold, depending on the dominance of one or another conduction mechanism, the temperature dependence of the specific volume resistivity ρ(T) of the polymer composite based on a matrix of ethylene vinyl acetate is significantly transformed. With an increase in the CB content, there is a decrease by several orders of magnitude in the maximum value of the relative resistivity ρ(T)_max/ρ₂₀ in its temperature dependence. Peroxide crosslinking of matrix macromolecules leads to a change in the nature of the temperature dependence of resistivity.
