以硝酸银为银源、乙二醇为还原剂和溶剂、聚乙烯吡咯烷酮为表面活性剂，在氯化钠辅助作用下快速合成了银纳米线。用扫描电子显微镜(SEM)、X射线衍射仪(XRD)与紫外-可见吸收光谱(UV-Vis)等方法对样品进行分析和表征。结果表明：在实验条件下，加入NaCl溶液体积为0.55 mL，反应时间为40 min时可获得较纯的银纳米线。最后，讨论了银纳米线的生长机理。
Sodium chloride assisted silver nanowires are rapidly synthesized by reduced silver salt with ethylene glycol in aqueous solution and in the presence of polyvinylpyrrolidone surfactant. The silver nanowires are characterized by scanning electron microscope (SEM),X-ray diffraction (XRD) and UV-Vis absorption spectroscopy. The results demonstrate that when 0.55 mL NaCl solution volume was added, and the reaction time was 40 min, the purer silver nanowires can be obtained. Finally, the growth mechanism of silver nanowires was also discussed.
