Silver nanowires (Ag NWs) with the length of approximately 60 µm and the diameter of approximately 300 nm are prepared via a simple, cost-effective, high-yield and eco-friendly procedure under a high molar concentration ratio of silver nitrate (AgNO) solution to poly(vinyl pyrrolidone) solution. The pre-synthesized Ag NWs were analysed by scanning electron microscopy, X-ray diffraction and UV-visible spectrophotometer. Furthermore, the as-prepared silver nanowires were roll-coated on the surfaces of the polyethylene terephthalate (PET) substrates. By optimizing the concentration of silver nanowire solution, the flexible Ag NW/PET transparent electrodes with a sheet resistance of 3.8 Ω sq at a transmittance of 70% can be fabricated. The results reported in this paper provide a basis for optimizing the growth of silver nanowires and performances of transparent electrodes.
通过在硝酸银（AgNO）溶液与聚乙烯吡咯烷酮溶液的高摩尔浓度比下，采用简单、经济高效、高产且环保的方法制备了长度约为60μm、直径约为300nm的银纳米线（Ag NWs）。通过扫描电子显微镜、X射线衍射和紫外可见分光光度计对预合成的Ag NWs进行了分析。此外，将制备好的银纳米线辊涂在聚对苯二甲酸乙二醇酯（PET）基板表面。通过优化银纳米线溶液的浓度，可以制备出在70%透光率下表面电阻为3.8Ω/sq的柔性Ag NW/PET透明电极。本文报道的结果为优化银纳米线的生长和透明电极的性能提供了依据。
