We prepared a hybrid electrode comprosed of a silver nanowires/poly (3,4-ethylenedioxythiophene): poly(styrenesulfonate) (AgNW/PEDOT:PSS) nanocomposite for flexible organic light-emitting diodes (FOLEDs). To increase the conductivity of PEDOT:PSS, diethylene glycol (DEG) was introduced into the PEDOT:PSS solution. The PEDOT:PSS layer shows a higher figure of merits (FoM) when prepared with the optimum amount of 7 vol%-DEG in the coating solution, due to the three-dimensional conducting network formed in the hybrid electrode. The perfluorinated ionomer (PFI) was also introduced into the PEDOT:PSS solution, and the resulting polymer solution was used to prepare a transparent anode on polymeric substrates. The PEDOT:PSS layers with higher contents of PFI exhibited higher work functions of 5.9 eV, due to control of the surface composition. After bending for 600,000 cycles, the hybrid electrode maintained a low R/R₀ value. When the hybrid electrode with PFI-PEDOT:PSS was used as a transparent anode in a flexible OLED device, the FOLED exhibited a 25% higher current efficiency. Therefore, the enhanced performance of the FOLED devices fabricated on PFI-PEDOT:PSS anodes could be applicable to flexible displays.

我们制备了由银纳米线/聚（3,4-亚乙基二氧噻吩）：聚（苯乙烯磺酸盐）（AgNW/PEDOT:PSS）纳米复合材料组成的混合电极，用于柔性有机发光二极管（FOLED）。为了增加 PEDOT:PSS 的电导率，将二甘醇 (DEG) 引入 PEDOT:PSS 溶液中。由于在混合电极中形成了三维导电网络，PEDOT:PSS 层在涂层溶液中以最佳量的 7 vol%-DEG 制备时显示出更高的品质因数 (FoM)。全氟离聚物 (PFI) 也被引入到 PEDOT:PSS 溶液中，所得聚合物溶液用于在聚合物基材上制备透明阳极。由于表面成分的控制，具有更高 PFI 含量的 PEDOT:PSS 层表现出更高的功函数，为 5.9 eV。₀值。当具有 PFI-PEDOT:PSS 的混合电极用作柔性 OLED 器件中的透明阳极时，FOLED 的电流效率提高了 25%。因此，在 PFI-PEDOT:PSS 阳极上制造的 FOLED 器件的增强性能可适用于柔性显示器。
