摘　　要：研究了以乙炔炭黑为导电粒子，ＨＤＰＥ、ＬＬＤＰＥ及粘接性树脂（接枝高密度聚乙烯（ｇＨＤＰＥ））为基体的导电复合物ＰＴＣ行为，电致发热特性及电压循环冲击试验。结果发现，ｇＨＤＰＥ／ＣＢ导电复合材料。The PTC characteristics, electrically indued heating performances and swithching on and off cycling test under voltage for HDPE/CB, LLDPE/CB, g HDPE/CB conductive composites were investigated. The results show that the PTC reproducibility and the rdsistance stability of g HDPE/CB and LLDPE/g HDPE/CB composites both are better than those of LLDPE/CB, HDPE/CB composites.
