The application of conductive polymer polypyrrole (PPY) towards transparent and flexible electronics has been demonstrated by a photolithography-compatible technique. The oxygen plasma pretreatment was found to be important for successful fabrication of PPY electrode patterns on flexible poly(ethylene terephthalate) (PET). By the patterning process of PPY, the transparency of PPY electrode can be improved up to >80% over the visible spectrum, which combined with the excellent chemical and physical stability of PPY shows the huge potential of PPY electrode as flexible transparent conductive electrode. In addition, PPY provides better interface connection for uniform deposition of organic semiconductor thin film. These outstanding advantages in PPY, coupled with selection of a novel anti-solvent and water-tolerant elastic dielectric, enable the photolithographic PPY patterns to be used for fabrication of large-scale flexible transparent organic field-effect transistor arrays. These results open up the capability of PPY as flexible transparent electrode for flexible organic devices, and exhibit a strong potential of PPY electrode patterns for future large-scale high-precision flexible electronics.
通过与光刻工艺兼容的技术，已经证明了导电聚合物聚吡咯（PPY）在透明和柔性电子产品方面的应用。发现氧气等离子体预处理对于在柔性聚对苯二甲酸乙二醇酯（PET）上成功制备 PPY 电极图案非常重要。通过 PPY 的图案化工艺，PPY 电极的透明度在可见光谱范围内可以提高到超过 80%，这与 PPY 的优异的化学和物理稳定性相结合，表明 PPY 电极作为柔性透明导电电极具有巨大的潜力。此外，PPY 为均匀沉积有机半导体薄膜提供了更好的界面连接。PPY 的这些突出优点，加上选择一种新型的抗溶剂和耐水弹性介电材料，使得光刻 PPY 图案可用于制造大规模柔性透明有机场效应晶体管阵列。这些结果展示了 PPY 作为柔性透明电极在柔性有机器件中的应用能力，并展示了 PPY 电极图案在未来大规模高精度柔性电子学中的强大潜力。
