Conductive polymers and nanocomposites have attracted great attention in industry and academia for their tremendous potential applications. Most of the research was focused on the type and amount of nano-additives used and fewer on their morphology which is critical in forming the conductive network. In this paper, a detailed investigation of the effect nanomaterial’s morphology was carried out to study their electrical conductivity properties. Silver nanowire (AgNW) nanocomposite and silver nanoparticle (AgNP) nanocomposite were fabricated. The morphology, crystallinity, and orientation of various silver nanofillers were characterized. AgNW based nanocomposites have shown a lower percolation threshold. A conductive unit based model was established to explain the evolution of the conductive network and aggregation. The aggregation geometry of nanofiller appeared as a dominant factor in altering the percolation behavior.

导电聚合物和纳米复合材料因其巨大的潜在应用而在工业和学术界引起了极大的关注。大多数研究都集中在使用的纳米添加剂的类型和数量上，而较少关注对形成导电网络至关重要的形态。在本文中，对效应纳米材料的形态进行了详细研究，以研究它们的导电性能。制备了银纳米线（AgNW）纳米复合材料和银纳米颗粒（AgNP）纳米复合材料。表征了各种银纳米填料的形态、结晶度和取向。基于 AgNW 的纳米复合材料显示出较低的渗透阈值。建立了基于导电单元的模型来解释导电网络和聚合的演变。
