我们描述了一种新的、简单的、室温湿化学方法，用于将金和银纳米颗粒组装成纳米线网络，而不使用光刻模板。通过机械搅拌含有纳米颗粒的水溶胶和甲苯的双相液体混合物，合成了直径为5至35纳米的纳米线，纳米线表面有一层薄薄的有机层。基于电子显微镜、紫外可见光谱和热重分析，讨论了纳米线的结构和表面化学。
We describe a new, simple, room-temperature wet-chemical approach for assembling Au and Ag nanoparticles into nanowire networks, without the use of lithographic templates. Five to 35 nm-diameter nanowires passivated with a thin organic layer were synthesized by mechanically agitating a biphasic liquid mixture of an aqueous hydrosol containing the nanoparticles, and toluene. Nanowire structure and surface chemistry are discussed based on electron microscopy, UV-visible spectroscopy and thermogravimetric analyses.
