Abstract
The dielectric constant and electrical conductivity of a composite of two insulators, poly(1,1-difluoroethylene) (yellow) and K(2)CO(3) (white), increased dramatically near the percolation threshold f(c) (f=concentration of K(2)CO(3)). This intriguing phenomenon can be interpreted in terms of interface percolation caused by the formation of chemically activated interfaces.
摘要
两种绝缘体聚（1,1-二氟乙烯）（黄色）和 K2CO3（白色）的复合材料的介电常数和电导率在渗流阈值 f(c)（f=K2CO3 的浓度）附近急剧增加。这种有趣的现象可以用化学激活界面形成引起的界面渗流来解释。
