摘　　要：由于质脆及成本昂贵等缺点,传统的透明导电材料铟锡氧化物(ITO)已不能满足柔性电子设备的需求。银纳米线具有高导电率、良好柔软性以及高透明度,被公认为是最具前景的ITO替代材料。它可以广泛应用于柔性透明电子设备,如可拉伸太阳能电池、可折叠智能手机以及有机发光二极管的透明导电薄膜(TCF)材料。以提高TCF透明度、降低薄层电阻为目标,本文从控制纳米银线的长径比、纳米线之间的接触电阻以及网络结构等几个方面,归纳总结了性能优良、工艺简单、可大规模制备Ag NWs的方法。In recent years, flexible and transparent electronic equipments have developed rapidly, such as stretchable solar cells, foldable smart phones, and flexible organic light-emitting diodes. The materials which play important roles in flexible and transparent electronic equipment, have attracted more and more attentions. Because of the excessive brittleness, however, the traditional transparent conductive material of indium tin oxide （ITO） cannot meet the needs of flexible electronic equipment, so many alternative materials appeared, such as carbon nanotubes, graphite, metal nanowires, and conductive polymers. Among them, the silver nanowires （Ag NWs） have become the most promising ITO alternative materials with high conductivity, good flexibility and high transparency. In this mini-review, the synthetic methods of the Ag NWs based on the aspect ratio, the contact between nanowires and network structure are summarized in the purpose of exploring the ways to obtain transparent conductive film （TCF） with high transparency and low sheet resistance.
