Abstract

Flexible organic light emitting diodes (OLED) have attracted great attention in many applications. MXene based flexible transparent conductive films (TCFs) are the most promising next-generation electrodes for flexible electronics. Herein, the sandwich conductive structure of silver nanowires (AgNWs) network, new 2D nanosheets with excellent conductivity, hydrophilicity and mechanical flexibility and PEDOT:PSS contributes to a highly transparent and conductive hybrid electrode through a simple, scalable, low-cost spray method. The TiCT/AgNWs/PEDOT-PET film shows a low sheet resistance (<30 Ω/sq) and high transmittance (>80%) at 550 nm. Flexible OLED with such hybrid anode has the maximum brightness, current efficiency and current density, as high as 10 040 cd m, 3.7 cd Aand 535.5 mA cm, respectively. These results indicate that the novel TiCT/AgNWs/PEDOT-PET TCFs have a great potential for high-performance flexible optoelectronic devices.

摘要

柔性有机发光二极管（OLED）在许多应用中引起了极大关注。基于MXene的柔性透明导电薄膜（TCF）是柔性电子学中最有前途的下一代电极。在此，银纳米线（AgNWs）网络、具有优异导电性、亲水性和机械柔韧性的新型二维纳米片以及PEDOT:PSS的三明治导电结构，通过一种简单、可扩展、低成本的喷涂方法，形成了一种高度透明且导电的混合电极。TiCT/AgNWs/PEDOT-PET薄膜在550 nm处显示出低方阻（<30 Ω/sq）和高透过率（>80%）。具有这种混合阳极的柔性OLED具有最高亮度、电流效率和电流密度，分别高达10040 cd m、3.7 cd A和535.5 mA cm。这些结果表明，新型TiCT/AgNWs/PEDOT-PET TCF在高性能柔性光电器件方面具有巨大潜力。
