| 摘 要： | 对ＬＤＰＥ／ＣＰＥ／炭黑三相复合导电体系的亚微形态和导电性能进行了研究。实验发现,该体系的亚微形态在共混比ＬＤＰＥ／ＣＰＥ大于和小于５０／５０时为典型的“海－岛”结构,在５０／５０时,为两相连续交错“互锁”结构;在共混比大于５０／５０时,ＬＤＰＥ／ＣＰＥ炭黑复合体系的导电性能较单一的ＬＰＤＰＥ树脂与炭黑复合体系的高２－５个数量级。

| Abstract: | In this paper, the morphology and electrical conductivity of LDPE/CPE/carbon black composites were studied.It was shown that depending on the composition, the composites may show "sea-island"structure or dual-continuous phases interlocking structure.Above the blend ratio of LDPE/CPE= 50/50,the electrical conductivity of LDPE/CPE/carbon black composites is higher more than 2-5 orders of magnitude than that of LDPE/carbon black composites,which is mainly caused by the heterogeneous distribution of carbon black particles in the two incompatible polymer components,i.e. LDPE and CPE. This experimental result indicates that addition of an incompatible polymer to a polymer filled with carbon black can be a new method to increase the electrical conductivity of polymer composites. |
