Copper nanowires are widely utilized for flexible electronics applications due to their excellent electrical conductivity, mechanical flexibility, and optical transparency with very low material cost. While many previous studies are dedicated to developing effective synthesis routes for copper nanowires, most of them have focused on the control of the morphology including length and diameter rather than synthesis yields. Although many postprocessing methods have been established to make use of the copper nanowires, there still remains crucial weakness in the nanowires against oxidation stability. In this study, a new synthesis method for the morphology control of copper nanowires as well as synthesis yields is introduced. After optimizing of the copper nanowire synthesis, a copper‐nanowire‐based flexible transparent conductor is fabricated as a highly robust electrode by using UV‐curable polyurethane acrylate resin. As a proof‐of‐concept, a flexible transparent capacitive‐force‐detection touch pad is demonstrated. The developed flexible transparent copper nanowire electrode with enhanced oxidation resistance is expected to be applied in various flexible and wearable electronics applications.

由高纵横比的铜纳米线制成的透明且柔性的电容式触摸板，具有增强的抗氧化性，适用于可穿戴电子产品

铜纳米线以其极低的材料成本而具有出色的导电性，机械柔韧性和光学透明性，因此被广泛用于柔性电子应用。尽管许多先前的研究致力于开发铜纳米线的有效合成路线，但大多数研究都集中在形态控制上，包括长度和直径，而不是合成产量。尽管已经建立了许多后处理方法来利用铜纳米线，但是纳米线在抗氧化稳定性方面仍然存在关键的弱点。在这项研究中，介绍了一种新的合成方法，用于控制铜纳米线的形貌以及合成产率。优化铜纳米线合成后，通过使用可紫外线固化的聚氨酯丙烯酸酯树脂，将铜纳米线为基础的柔性透明导体制成了高度耐用的电极。作为概念验证，展示了一个灵活的透明电容力检测触摸板。具有增强的抗氧化性的已开发的柔性透明铜纳米线电极有望用于各种柔性和可穿戴电子应用中。
