A photochemical method has been exploited for the synthesis of electrically conductive silver (Ag) nanowires in a polymer solution in the presence of negatively charged Au seed particles. The synthesis was completed within 8 min of UV-photoirradiation in ambient conditions. The nanowires were fabricated on a PVA template having an average diameter of 135+/-20 nm and a length of 10-20 microm. The current-voltage (I-V) characterization showed that the PVA-Ag nanowires were continuous, having Ohmic behavior with low contact resistance. Results indicate that the PVA acted as a reducing agent, stabilizing agent, and a template for the nucleation and growth of Ag nanowires. The Ag deposition was highly selective and on the PVA only. Our research indicated that the PVA-Ag nanowires might be useful as interconnects in nanoscale integrated circuitry, functional nanodevices, and in optoelectronics.
一种光化学方法已被开发用于在聚合物溶液中合成导电银（Ag）纳米线，其中存在带负电荷的 Au 种子颗粒。在环境条件下进行 UV 光照射 8 分钟内即可完成合成。纳米线是在具有平均直径为 135±20nm 和长度为 10-20μm 的 PVA 模板上制造的。电流-电压（I-V）特性表明，PVA-Ag 纳米线是连续的，具有低接触电阻的欧姆行为。结果表明，PVA 起到了还原剂、稳定剂和 Ag 纳米线成核和生长的模板的作用。Ag 的沉积具有高度选择性，仅在 PVA 上进行。我们的研究表明，PVA-Ag 纳米线可能在纳米级集成电路、功能纳米器件和光电子学中用作互连。
