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.
