Low-cost fabric-based top-emitting polymer light-emitting devices (Fa-TPLEDs) have aroused increasing attention due to their remarkable potential applications in wearable displays. However, it is still challenging to realize efficient all-solution-processed devices from bottom electrodes to top electrodes with large-scale fabrication. Here, a smooth reflective Ag cathode integrated on fabric by one-step silver mirror reaction and a composite transparent anode of polydimethylsiloxane/silver nanowires/poly(3,4-ethylenedioxythiophene):poly(styrenesulfonate) via a water-assisted peeling method are presented, both of which possess excellent optoelectrical properties and robust mechanical flexibility. The Fa-TPLEDs are constructed by spin-coating functional layers on the bottom reflective cathodes and laminating the top transparent anodes. The Fa-TPLEDs show a current efficiency of 16.3 cd A−1, an external quantum efficiency of 4.9% and angle-independent electroluminescence spectra. In addition, the Fa-TPLEDs possess excellent mechanical stability, maintaining a current efficiency of 14.3 cd A−1 after 200 bending cycles at a radius of 4 mm. The results demonstrate that the integration of solution-processed reflective cathodes and transparent anodes sheds light on a new avenue to construct low-cost and efficient fabric-based devices, showing great potential applications in emerging smart flexible/wearable electronics.

用于可穿戴电子产品的高效柔性基于织物的顶发射聚合物发光器件
低成本的基于织物的顶发射聚合物发光器件（Fa-TPLED）由于其在可穿戴显示器中的巨大潜在应用而引起了越来越多的关注。然而，大规模制造从底部电极到顶部电极的高效全溶液加工器件仍然具有挑战性。在此，提出了一种通过一步银镜反应集成在织物上的光滑反射银阴极和通过水辅助剥离方法制备的聚二甲基硅氧烷/银纳米线/聚(3,4-乙撑二氧噻吩):聚(苯乙烯磺酸盐)复合透明阳极，两者都具有优异的光电性能和强大的机械灵活性。 Fa-TPLED 是通过在底部反射阴极上旋涂功能层并层压顶部透明阳极而构建的。 Fa-TPLED显示出16.3 cd A -1的电流效率、4.9%的外量子效率和与角度无关的电致发光光谱。此外，Fa-TPLED具有优异的机械稳定性，在4mm半径下进行200次弯曲循环后，电流效率仍保持在14.3cdA -1 。结果表明，溶液处理的反射阴极和透明阳极的集成为构建低成本、高效的基于织物的设备提供了一条新途径，在新兴智能柔性/可穿戴电子产品中显示出巨大的潜在应用。
