摘 要: 探索了聚丙烯/炭黑导电复合材料在不同的通电状态及不同的工艺条件下的电压—电流特性、正温度系数效应及起动态性能。结果表明,炭黑的种类、添充量及添加剂将改变复合材料的发热特性。并且聚丙烯/炭黑导电复合材料的非欧姆性质明显。 PP/CB composite heat generation behavior by of at difference current and technologic condition were investigated. The results show that the additive quantity kinds and of CB,and other filler will change its thermal behavior. The nolinear characteristioc of current-voltage is obvious of pp/CB composites
