Herein, a novel photolithographic stretchable transparent hybrid electrode comprising spin-coated poly(3,4-ethylenedioxythiophene):poly(styrenesulfonate) (PEDOT:PSS) and a spray-coated single-wall carbon nanotube (SWCNT) network was prepared via one-step photolithography and all-dry etching. The PEDOT:PSS layer provided good interface wettability for the SWCNT aqueous dispersion to form an ultrathin uniform conductive film, which not only allowed the production of a photolithographic high-precision versatile electrode pattern, but also simultaneously ensured that the stretchable transparent electrode had the high optical transparency of up to 84% at 550 nm and good cyclic stretching stability. The photolithographic stretchable transparent electrodes, combined with a spin-coated dioctyl[1]benzothieno [3,2-b][1] benzothiophene (C₈-BTBT) thin film and a mechanical lamination strategy, realized a photolithography-compatible all-solution-processed transparent conformal organic transistor array with the highest mobility of up to 2.7 cm² V⁻¹ s⁻¹ and good operation stability in an LED driving circuit.

用于全溶液处理的全透明共形有机晶体管阵列的光刻可拉伸透明电极†

在此，一种新型光刻伸缩性透明复合包括旋涂聚（3,4-亚乙基）电极：制备：（PSS PEDOT）和所述的喷镀膜的单壁碳纳米管（SWCNT）网络聚（苯乙烯磺酸盐）经由一维步骤光刻和全干蚀刻。PEDOT：PSS层为SWCNT水分散液提供了良好的界面润湿性，从而形成了超薄均匀的导电膜，这不仅可以生产出光刻高精度的通用电极图案，而且还可以确保可拉伸透明电极具有较高的润湿性。在550 nm处的光学透明度高达84％，并具有良好的循环拉伸稳定性。光刻可拉伸透明电极，与旋涂二辛基[1]苯并噻吩并[3,2-b ] [1]苯并噻吩（C ₈ -BTBT）薄膜和机械层压的策略，实现了与向上的最高迁移率的光刻兼容所有溶液处理透明保形有机晶体管阵列2.7厘米² V ^-1小号^{- 1}和LED驱动电路中良好的操作稳定性。
