Silver nanowires (AgNWs) have been considered as replacements of indium tin oxide (ITO) due to superior optoelectronic properties and mechanical stability for flexible electronics. However, high cost and process complexity of patterning process disturb their applicability to commercial products. Herein, a facile patterning method of AgNWs by using inkjet‐printed conductive polymer templates is developed, which can be applied on various surfaces including super hydrophobic light‐emitting organic layer. Combination of inkjet and transfer printing processes rendered high degree of freedom both in customizing patterns and in tuning transparency and conductivity simultaneously. AgNWs are selectively transferred from a donor elastomer onto formulated adhesive conductive polymer patterns. By changing thickness of the AgNW networks flood‐coated on the elastomer, their transparency and conductivity can be tuned during the transfer process. AgNW transparent electrodes on plastic substrates have much higher figure of merit than that of ITO on plastic substrate. The selective transfer process simultaneously solves inherent issues of the AgNW electrodes such as poor adhesion to various surfaces, surface roughness, and fine pattern formation. Finally, with superior optoelectronic property and mechanical flexibility of the electrodes, various flexible electronic applications are demonstrated.

通过在各种表面上形成的喷墨印刷导电聚合物模板，高度可定制的透明银纳米线图案

银纳米线（AgNWs）由于其优异的光电性能和柔性电子产品的机械稳定性而被视为铟锡氧化物（ITO）的替代品。然而，构图工艺的高成本和工艺复杂性干扰了它们对商业产品的适用性。本文中，开发了一种通过使用喷墨印刷的导电聚合物模板对AgNWs进行便捷构图的方法，该方法可以应用于包括超疏水发光有机层在内的各种表面。喷墨和转移印刷工艺的结合在定制图案以及同时调节透明度和导电性方面都具有高度的自由度。将AgNW从供体弹性体选择性转移到配制的粘合剂导电聚合物图案上。通过改变涂在弹性体上的AgNW网络的厚度，可以在转移过程中调整其透明度和电导率。塑料基板上的AgNW透明电极的品质因数比塑料基板上的ITO高。选择性转移过程同时解决了AgNW电极的固有问题，例如对各种表面的附着力差，表面粗糙度大，图案形成精细。最后，具有优异的光电性能和电极的机械柔韧性，展示了各种柔韧性电子应用。选择性转移过程同时解决了AgNW电极的固有问题，例如对各种表面的附着力差，表面粗糙度大，图案形成精细。最后，具有优异的光电性能和电极的机械柔韧性，展示了各种柔韧性电子应用。选择性转移过程同时解决了AgNW电极的固有问题，例如对各种表面的附着力差，表面粗糙度大，图案形成精细。最后，具有优异的光电性能和电极的机械柔韧性，展示了各种柔韧性电子应用。
