Core-sheath silver nanowire/polyvinylpyrrolidone (AgNW/PVP) nanocables have been fabricated via an efficient single-spinneret electrospinning method. The core-sheath structure is revealed by combining several characterization methods. A possible formation mechanism of the AgNW/PVP nanocable involving a strong stretching during the electrospinning process is proposed. Further, electrical measurements were performed on AgNW/PVP nanocables as well as bare AgNWs, which indicated the nanocables became insulating due to the isolation of highly conductive AgNWs by insulating PVP sheath. Therefore, the described fabrication method holds potential for the fabrication of low-cost metal/polymer composite materials for nanoelectronic applications in general.
通过高效的单喷丝头静电纺丝方法制备了核壳银纳米线/聚乙烯吡咯烷酮（AgNW/PVP）纳米电缆。通过结合几种表征方法揭示了核壳结构。提出了一种涉及静电纺丝过程中强拉伸的 AgNW/PVP 纳米电缆的可能形成机制。进一步对 AgNW/PVP 纳米电缆以及裸露的 AgNW 进行了电测量，结果表明，由于高度导电的 AgNW 被绝缘的 PVP 鞘隔离，纳米电缆变为绝缘。因此，所描述的制造方法为用于纳米电子应用的低成本金属/聚合物复合材料的制造提供了潜力。
