| 摘 要： | 有机发光二极管(organic light emitting diodes, OLEDs)可以柔性制备，在未来的可穿戴应用上有广阔的发展前景，而柔性透明电极(flexible transparent electrode, FTE)的性能直接影响着柔性OLED的性能。本文基于银纳米线(AgNWs)和聚(3,4-乙烯二氧噻吩)∶聚苯乙烯磺酸(PEDOT∶PSS)制备了FTE,并采用甲醇浸渍、氩等离子处理、紫外辐射3种不同的方式对该电极进行处理，优化FTE的光电性能。研究发现：甲醇浸渍，可减少AgNWs上聚合物的包覆；等离子体处理和紫外辐射，可对AgNWs进行焊接；而两种方式的协同作用则可以对FTE的光电性能进一步优化。实验获得最优FTE的方阻为14.18Ω/sq,在550 nm处的透过率可达到84%以上。经过500次弯曲测试后，FTE的方阻变化率低于15%。本文的工作对FTE的制备及优化提供了可行性方案。

| Abstract: | Organic light emitting diodes (OLEDs) have a broad prospect for development in future wearable diodes due to its flexible manufacturing and the performance of flexible transparent electrodes (FTEs) affects that of flexible OLED.In this paper,the FTE was fabricated based on the silver nanowires (AgNWs) and poly(3,4-ethylenedioxythiophene)∶poly(styrenesulfonate) (PEDOT∶PSS),which was treated by methanol impregnation,Ar plasma treatment and ultraviolet radiation to optimize the optoelectronic properties of FTE.It was found that methanol impregnation could reduce polymer coating on AgNWs,AgNWs could be welded by Ar plasma treatment and ultraviolet treatment,as well as the synergistic effect of two methods can further optimize the photoelectric properties of FTE.The sheet resistance of the optimal FTE is 14.18 Ω/sq,and the transmittance at 550 nm is more than 84%.The sheet resistance change rate of FTE is less than 15% after 500 bending tests.This work provides a feasible scheme for the preparation and optimization of FTE. |
