将纳米线组装成具有新功能的有序宏观结构是最近的研究热点。在这封信中,我们报道了一种通过流过玻璃毛细管来制备高长径比的亲水性银纳米线的新方法。目前的玻璃毛细管内部有清晰的银纳米线膜,可以作为一种便携式的、可重复使用的表面增强拉曼光谱(SERS)衬底,这可能为检测混合污染物提供一个通用的、有前途的平台。通过控制纳米线悬浮液的流动参数,最初随机排列的银纳米线可以形成密度可调的纳米线阵列,形成附着在毛细管内壁上的弧形纳米线膜。与Langmuir-Blodgett(LB)法制备的平面有序银纳米线薄膜相比,弧形纳米线薄膜具有更好的表面增强拉曼散射性能。
Assembly of nanowires into ordered macroscopic structures with new functionalities has been a recent focus. In this Letter, we report a new route for ordering hydrophilic Ag nanowires with high aspect ratio by flowing through a glass capillary. The present glass capillary with well-defined silver nanowire films inside can serve as a portable and reusable substrate for surface-enhanced Raman spectroscopy (SERS), which may provide a versatile and promising platform for detecting mixture pollutions. By controlling the flow parameters of nanowire suspensions, initially random Ag nanowires can be aligned to form nanowire arrays with tunable density, forming cambered nanowire films adhered onto the inner wall of the capillary. Compared with the planar ordered Ag nanowire films by the Langmuir-Blodgett (LB) technique, the cambered nanowire films show better SERS performance.
