The interphase region around nanoparticles changes the percolation threshold of long and thin nanoparticles, such as carbon nanotubes (CNT) in polymer nanocomposites. In this paper, the effects of the interphase region on the percolation threshold of nanoparticles and the network fraction are studied. New percolation threshold () is defined by the role of the interphase in the excluded volume of nanoparticles (V). Moreover, the influences of filler and interphase size on the percolation volume fraction, the fraction of nanoparticles in the network as well as the volume fraction and relative density of the filler network are investigated. The least ranges of "" are obtained by thin and long CNT. Similarly, a thick interphase increases the "V" parameter, which causes a positive role in the percolation occurrence. Also, thin CNT and a thick interphase cause the high fraction of the filler network in the nanocomposites.
纳米颗粒周围的界面区域会改变长而细的纳米颗粒（如聚合物纳米复合材料中的碳纳米管（CNT））的渗流阈值。本文研究了界面区域对纳米颗粒渗流阈值和网络分数的影响。新的渗流阈值（）由界面在纳米颗粒排除体积（V）中的作用定义。此外，还研究了填料和界面尺寸对渗流体积分数、网络中纳米颗粒分数以及填料网络的体积分数和相对密度的影响。通过细而长的碳纳米管获得了“”的最小范围。同样，较厚的界面会增加“V”参数，这对渗流的发生起到积极作用。此外，细碳纳米管和较厚的界面会导致纳米复合材料中填料网络的高分数。
