The increasing demand for the state-of-the-art transparent conductive electrodes has received great interest in synthesizing silver nanowires (AgNWs) with a uniform diameter that exhibit excellent conductance, transparency, flexibility and mechanical ductility. Herein, we report the controllable synthesis of ultrathin AgNWs with high aspect ratio via a polyol-assisted process. The diameter of AgNWs can be continuously modulated from 20 to 80 nm by simply adjusting the aging time. The self-assembled films fabricated by using AgNWs with a diameter of 20 nm as building blocks enable an excellent performance and show a sheet resistance of ∼30 Ω/sq and an optical transmittance of 94%. In addition, such nanowire-based conductive films can keep the excellent flexibility and resistance after bending 10,000 cycles. Similarly, the intelligent dimming films prepared by this AgNW films also have excellent flexibility and stability.

对最新技术的透明导电电极的需求日益增长，人们对合成具有均匀直径，表现出优异电导率，透明性，柔韧性和机械延展性的银纳米线（AgNW）引起了极大的兴趣。在本文中，我们报道了超薄具有高纵横比AgNWs的可控合成通过多元醇辅助工艺。通过简单地调节老化时间，可以将AgNW的直径连续地从20纳米调节到80纳米。通过使用直径为20 nm的AgNWs作为构件来制作的自组装膜具有出色的性能，并具有约30Ω/ sq的薄层电阻和94％的透光率。另外，这样的基于纳米线的导电膜在弯曲10,000次之后可以保持优异的挠性和电阻。类似地，由该AgNW膜制备的智能调光膜也具有优异的柔韧性和稳定性。
