摘要
模拟了导电介质填充聚合物体系的二维点阵逾渗过程 ,研究了分散工艺对导电性复合材料逾渗形成过程的影响 ,以及HDPE/CB复合体系导电粒子的分布状态对其逾渗网络及导电特性的影响。根据在低填充体积分数时逾渗的发生是粒子不均匀分散这一原理 ,阐述了PTC材料设计制作的注意事项。
It simulated the percolation process in 2-dimention lattice of conductive particles filled polymer, and studied the influencing effects of dispersion process on the percolation process of the conductive composites and the effects of the distribution state of conductive particles in HDPE/CB composites on its percolation network and conductive behavior. It also elaborated the key points of designing and producing the PTC material, which based on the principle of the percolation process resulted from the uneven dispersion of conductive particles in case of the volume fraction of the conductive particles was low.
