最近，通过使用银和铜纳米线已经成功地制造了柔性透明电极。银是昂贵且稀缺的，而铜是廉价的，但它需要复杂的后处理工艺来获得具有等效性能的铜纳米线电极。在这项研究中，通过使用基于聚乙烯吡咯烷酮的墨水和超长铜纳米线，一个简单的和低成本的方法已经提出了用于制造优良的铜纳米线为基础的柔性透明电极。当将0.5wt%的纵横比的铜纳米线和基于聚乙烯吡咯烷酮的油墨施加以涂覆到基底上时，后处理过程可以简化为在乙酸中浸渍一次60秒。与以前报道的研究相比，我们的铜纳米线电极被证明是质量最好的透明电极之一。此外，这些电极被成功地应用于自电容按钮触摸传感器的制作。
Recently, flexible transparent electrodes have been fabricated successfully by using silver and copper nanowires. Silver is expensive and scarce, while copper is inexpensive but it requires a complex post-treatment process to obtain copper nanowire electrodes with an equivalent performance. In this study, by using polyvinylpyrrolidone-based ink and ultralong copper nanowires, a simple and low-cost approach has been presented for the fabrication of excellent copper nanowire-based flexible transparent electrodes. When ultrahigh aspect ratio copper nanowires and 0.5 wt % polyvinylpyrrolidone-based ink are applied to coat onto a substrate, the post-treatment process can be simplified to dipping once in acetic acid for 60 s. When compared to previously reported studies, our copper nanowire electrodes proved to be one of the best quality transparent electrodes. Moreover, these electrodes were applied successfully in the fabrication of self-capacitance button touch sensors.
