Copper nanowires (CuNWs) are becoming an indispensable item for next-generation transparent optical devices due to their excellent conductivity and transparency. In this work, ultrathin semicircle-shaped copper nanowires(SCuNWs) with a diameter of ∼ 15 nm and a length of ∼ 30 μm (aspect ratio of ∼2,000) were synthesized in ethanol solution. The mechanism and factors that affect the morphology and dispersity of the SCuNWs were investigated. The prepared SCuNWs were coated on polyethylene terephthalate (PET) or polydimethylsiloxane (PDMS) substrate to fabricate flexible transparent conductors (FTCs). The fabricated FTCs exhibited excellent optoelectrical performance and low haze. In addition, the fabricated FTCs showed high mechanical stability during stretching and bending, indicating their great potential in flexible optical devices.

低雾度柔性透明导体乙醇溶液中超薄半圆形铜纳米线的合成

铜纳米线（CuNWs）由于其出色的导电性和透明性，已成为下一代透明光学设备必不可少的产品。在这项工作中，在乙醇溶液中合成了直径约为15 nm，长度约为30μm（纵横比约为2,000）的超薄半圆形铜纳米线（SCuNWs）。研究了影响SCuNWs形貌和分散性的机理和因素。将制备的SCuNWs涂覆在聚对苯二甲酸乙二醇酯（PET）或聚二甲基硅氧烷（PDMS）基底上，以制造柔性透明导体（FTC）。制成的FTC表现出出色的光电性能和低雾度。此外，制造的FTC在拉伸和弯曲过程中显示出很高的机械稳定性，表明它们在柔性光学器件中的巨大潜力。
