Silver nanowires-embedded polydimethylsiloxane (AgNWs/PDMS) electrodes are promising components for various soft electronics, but face energy mismatch with organic semiconductors. Attempts at galvanic replacement, involving spontaneous gold (Au) formation on the electrodes, often result in non-uniform and particulate Au coatings, compromising device performance and stability. In this study, we introduce a novel approach for achieving a uniform and complete Au coating on AgNWs/PDMS electrodes by adding NaCl to the Au complex solution. This addition slows down the galvanic replacement process and prevents precipitation, enabling a uniform and complete Au coating on the AgNWs surface. Such coating significantly reduces contact resistance (R_C), thereby enhancing the electrical characteristics of p-type organic transistors. Furthermore, the development of high-performance, fully soft organic transistors was achieved incorporating an organic semiconductor-elastomer blend. Additionally, reliable, mechanically stable soft glucose sensor was developed, taking advantage of the complete Au coating, which protects against oxidation during the glucose sensing process.

银纳米线嵌入的聚二甲基硅氧烷 （AgNWs/PDMS） 电极是各种软电子器件的有前途的组件，但与有机半导体存在能量不匹配。尝试电流置换，包括在电极上自发形成金 （Au），通常会导致不均匀和颗粒状的 Au 涂层，从而影响器件的性能和稳定性。在这项研究中，我们介绍了一种通过在 Au 配合溶液中添加 NaCl 在 AgNWs/PDMS 电极上实现均匀和完整的 Au 涂层的新方法。这种添加减慢了电偶置换过程并防止沉淀，从而在 AgNWs 表面形成均匀和完整的 Au 涂层。这种涂层显著降低了接触电阻 （R_C），从而增强了 p 型有机晶体管的电气特性。此外，还开发了高性能、全软的有机晶体管，并结合了有机半导体-弹性体混合物。此外，还开发了可靠、机械稳定的软葡萄糖传感器，利用完整的 Au 涂层，防止葡萄糖传感过程中的氧化。
