A simple, low-cost, and reliable process of production for conductive tracks and their transfer to poly(dimethylsiloxane) (PDMS) substrate has been proposed. Flexible electrodes were fabricated using conductive nanoparticulates under intensive pulsed light, which were then transferred on to a PDMS substrate via a pouring, curing, and peeling process. The combination of copper-silver nitrate-graphene nanoplatelets (GnPs) provided multiple benefits to the conductive tracks, such as oxidation resistance and increased durability on PDMS. The addition of silver nitrate reduced the speed of oxidation during the curing process of PDMS in the presence of heat and air. The addition of GnPs then increased the stability of conductive tracks on PDMS, whereas the films without GnPs were not conductive on PDMS due to mechanical cracks. The copper-silver-GnP electrodes on PDMS were successfully demonstrated as flexible electrodes and reveal the enhancement of oxidation resistance during thermal oxidation for Joule heater application.
已经提出了一种简单、低成本且可靠的生产导电轨道及其向聚二甲基硅氧烷（PDMS）基底转移的方法。使用高强度脉冲光制备了使用导电纳米颗粒的柔性电极，然后通过浇铸、固化和剥离工艺将其转移到 PDMS 基底上。铜-硝酸银-石墨烯纳米片（GnPs）的组合为导电轨道提供了多种好处，例如抗氧化性和在 PDMS 上增加的耐用性。硝酸银的添加降低了 PDMS 在加热和空气存在下的固化过程中的氧化速度。GnPs 的添加增加了导电轨道在 PDMS 上的稳定性，而没有 GnPs 的薄膜由于机械裂纹而在 PDMS 上不导电。PDMS 上的铜-银-GnP 电极成功地被证明为柔性电极，并揭示了在焦耳加热器应用的热氧化过程中抗氧化性的增强。
