Data from: Flexible transparent electrodes based on silver nanowires synthesized via a simple method

Silver nanowires (Ag NWs) with the length of ～60 μm and the diameter of ～300 nm are prepared via a simple, cost-effective, high-yield and eco-friendly procedure under a high molar concentration ratio of silver nitrate (AgNO3) solution to Poly(vinyl pyrrolidone) (PVP) solution. The pre-synthesized Ag NWs were analyzed by scanning electron microscopy (SEM), X-ray diffraction (XRD) 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-1 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.

本研究通过硝酸银（silver nitrate, AgNO3）与聚乙烯吡咯烷酮（Poly(vinyl pyrrolidone), PVP）的高摩尔浓度比反应体系，采用简便、低成本、高产量且环境友好的工艺，成功制备了长度约60 μm、直径约300 nm的银纳米线（silver nanowires, Ag NWs）。研究采用扫描电子显微镜（scanning electron microscopy, SEM）、X射线衍射（X-ray diffraction, XRD）及紫外-可见分光光度计对预合成的银纳米线进行了表征分析。此外，将所制备的银纳米线通过辊涂法负载于聚对苯二甲酸乙二酯（polyethylene terephthalate, PET）基底表面。通过优化银纳米线分散液的浓度，可制备出在70%透光率下方块电阻为3.8 Ω sq⁻¹的柔性Ag NW/PET透明电极。本研究结果为银纳米线的生长优化以及透明电极的性能优化提供了重要依据。
