在这篇文章中，有机发光电化学电池（OLECs）已被制作在由一个标准的编织聚酯棉纺织品的基板上。纺织品基底通过首先丝网印刷紫外线（UV）可固化聚氨酯层（称为界面层）来预平滑。然后利用溶液处理的喷涂将所有功能层存款在纺织品上，以实现完全喷涂的柔性有机发光二极管。OLEC器件最初是在ITO涂层的玻璃基板上制造的，用于工艺优化。然后，使用优化的喷涂工艺在柔性织物上制备了OLEC。最后，在周围环境中测试之前，通过模板印刷环氧树脂封装玻璃和纺织品衬底上的OLEC器件。ITO涂层玻璃上的OLEC的开启电压为3 V，亮度水平为200 cd/m（2），寿命至少为60 min。纺织品上的OLEC的开启电压为4 V，亮度水平为80 cd/m（2），寿命至少为30 min。
In this article, organic light-emitting electrochemical cells (OLECs) have been fabricated on a substrate consisting of a standard woven polyester cotton textile. The textile substrate is presmoothed by first screen printing an ultraviolet (UV) curable polyurethane layer, termed the interface layer. Solution-processed spray coating is then utilized to deposit all the functional layers on the textile to achieve fully spray-coated flexible OLECs. OLEC devices were initially fabricated on ITO-coated glass substrates for process optimization. Then, the OLECs were fabricated on flexible textile using the optimized spray coating process. Finally, both OLECs devices on the glass and textile substrates were encapsulated by stencil printing epoxy before testing in an ambient environment. The OLECs on ITO-coated glass exhibit a turn-on voltage of 3 V, a brightness level of 200 cd/m(2) and a lifetime of at least 60 min. The OLECs on textile exhibit a turn-on voltage of 4 V, a brightness level of 80 cd/m(2) level and a lifetime of at least 30 min.
