摘要: 研究了LDPE/CPE/炭黑三相复合导电体系的导性能和电流-电压特性。实验结果表明复合体系具有明显的导电渗滤效应,在共混比LDPE/CPE>50/50时,导电性能随CPE含量增加而显著提高,这主要是由于炭黑粒子在LDPE和CPE两组分分中的分布不均匀性所致。Abstract: In this Paper, the electrical conductivity and current-voltage (I-U) characteristics of LDPE / CPE / CB electrical conductive composites were studied. It shows that the composites possess notable Percolation effect. Above the blend ratio of LDPE / CPE =5
