摘要
为了探究导电填料对导电网络的构建，以及不同种类和含量的导电填料对导电高分子复合材料(CPCs)电性能的影响，选用多壁碳纳米管(MWCNTs)和炭黑(CB)作为导电填料，聚碳酸酯(PC)和聚偏氟乙烯(PVDF)为高分子基体，通过熔融共混制备双逾渗结构的PC/PVDF共混物复合材料。通过选择性刻蚀PC，发现PC/PVDF质量比为40/60时形成共连续结构的CPCs；通过热力学计算预测和扫描电镜观察发现MWCNTs和CB两种填料均选择性分散在PVDF相，共连续结构和选择性分布导致CPCs的电逾渗阈值为0.03 wt%；在相同MWCNTs填料量下，CPCs的电性能随着CB掺杂量的增加而增加，这是因为掺杂的CB在导电网络中起到了桥接MWCNTs的作用；同时利用光学显微镜定量分析了导电填料在基体中的分布，随着CB含量的增加，共连续结构没有发生变化，但联用填料的团聚体面积呈现上升趋势。
Abstract
In order to investigate the effect of conductive fillers on the construction of conductive network and the effect of different types and contents of conductive fillers on the electrical properties of conductive polymer composites (CPCs)
multi-walled carbon nanotubes (MWCNTs) and carbon black (CB) were selected as conductive fillers
and polycarbonate (PC) and poly(vinylidene fluoride) (PVDF) were selected as polymer matrix. PC/PVDF blends with double percolation structure were prepared by melt blending. By selective etching of PC
it was found that CPCs with co-continuous structure were formed when the mass ratio of PC/PVDF was 40/60. It was found that MWCNTs and CB fillers were selectively dispersed in the PVDF phase by thermodynamic calculation and SEM observation. The co-continuous structure and selective distribution resulted in the electrical percolation threshold of 0.03 wt%. With the same amount of MWCNTs filler
the electrical properties of CPCs increased with the increase of CB content
because the doped CB played a role in bridging the MWCNTs in the conductive network. At the same time
the distribution of the conductive filler in the matrix was quantitatively analyzed by optical microscope. With the increase of CB content
the co-continuous structure did not change
but the aggregate area of the combined filler showed an increasing trend.
