在这项工作中，通过简单的剥离方法无需任何后处理即可制备出透明导电且柔性的银纳米线/聚酰亚胺（AgNW/PI）复合薄膜，其平均品质因数高达111.3（电子电导率与光导率之比）。当采用AgNW/PI复合薄膜作为蓝色聚合物发光二极管中的柔性透明导电阳极时，该器件表现出3.42%的高外量子效率，与基于刚性氧化铟锡（ITO）的控制器件3.96%的效率相当。此外，以AgNW/PI为透明导电阳极的柔性印刷聚合物太阳能电池（PSC）实现了4.01%的高功率转换效率，这也与刚性ITO基PSC相当。该工作系统地论证了AgNW/PI复合薄膜在各类柔性光电器件中具有广阔的应用前景。
In this work, transparent and conductive as well as flexible silver nanowire/polyimide (AgNW/PI) composite film with an average figure of merit as high as 111.3, which is the ratio of electronic conductivity to optical conductivity, is produced by a simple peel-off method without any post treatments. When employing the AgNW/PI composite film as the flexible transparent conductive anode in blue polymer light-emitting diodes, the device shows a high external quantum efficiency of 3.42% which is comparable to the rigid indium tin oxide (ITO)-based control device with an efficiency of 3.96%. Moreover, for the flexible printed polymer solar cell (PSCs) with AgNW/PI as the transparent conductive anode, a high power conversion efficiency of 4.01% is achieved, which is also comparable to that of the rigid ITO-based PSC. This work systematically demonstrates that AgNW/PI composite film has a promising prospect for application in all kinds of flexible optoelectronic devices.
