Abstract Silver nanowires (AgNWs) are remarkable components that may be able to replace indium tin oxide (ITO) as transparent electrodes. However, a common coating method can cause poor conductivity and adhesively because of the creation of randomly organized connections of Ag NWs. These problems should be overcome in AgNW networks for transparent electrodes through material and engineering approaches. In this work, novel AgNW based transparent conductive electrodes (TCEs) on a flexible polycarbonate (PC) substrate, with synchronously improved adhesivity and reduced resistivity, are prepared via hot lamination process. The sheet resistance of the treated AgNW networks decreases from 100 to 12.5 Ω/sq. at optical transmittance of 94.5%. Calculation of figure of merit (FOM) displays a high value of 187, which is superior to that obtained from the flexible ITO, carbon nanotubes, graphene, and other metal nanowires. Meanwhile, the sheet resistance is almost unchanged after 30 tape tests, suggesting an outstanding adhesion of AgNW networks to the flexible substrate. In addition, the treated AgNW networks show small bending radius of 3.0 mm, indicating good flexibility. These results illustrate a promising alternative to traditional transparent conductive films for wearable electronic devices.

通过简单的热层压工艺同时提高柔性 AgNW 网络的导电性和附着力

摘要 银纳米线 (AgNW) 是一种卓越的组件，可以替代氧化铟锡 (ITO) 作为透明电极。然而，由于 Ag NW 的随机组织连接的产生，常见的涂层方法会导致导电性和粘附性较差。这些问题应该通过材料和工程方法在透明电极的 AgNW 网络中得到克服。在这项工作中，通过热层压工艺在柔性聚碳酸酯 (PC) 基板上制备了新型基于 AgNW 的透明导电电极 (TCE)，具有同步提高的粘附性和降低的电阻率。处理过的 AgNW 网络的薄层电阻从 100 降至 12.5 Ω/sq。光透射率为 94.5%。品质因数 (FOM) 的计算显示为 187 的高值，这优于从柔性 ITO、碳纳米管、石墨烯和其他金属纳米线获得的。同时，在 30 次胶带测试后，薄层电阻几乎没有变化，这表明 AgNW 网络对柔性基板的附着力非常出色。此外，经过处理的 AgNW 网络显示出 3.0 mm 的小弯曲半径，表明具有良好的柔韧性。这些结果说明了用于可穿戴电子设备的传统透明导电薄膜的有前途的替代品。
