| 摘 要： | 本文报道了一种在水溶液中室温下方便地制备铜纳米线的方法。发现反应过程中会先形成小的铜纳米颗粒,在乙二胺的取向诱导作用下这些小的纳米颗粒能生长成纳米线。可以经过离心过程使产物(产物一般是铜纳米线和纳米颗粒的混合物)得到纯化。用透射电子显微镜(TEM)对所得铜纳米线进行了表征,发现这些铜纳米线的直径约85纳米,长度可达几十微米。研究还发现所得铜纳米材料的形状与反应温度密切相关。本文也对可能的铜纳米线形成机理进行了讨论。

| Abstract: | This paper describes a soft,facile aqueous solution approach to the synthesis of uniform bicrystalline copper nanowires at ambient temperature. It is involved the formation of small copper nanoparticles during the reaction. Due to the direct action of ethylenediamine,these small copper nanoparticles grow up to nanomaterials. Copper nanowires were obtained through a purification process and were characterized by transmission electron microscopy (TEM). It was found that the shapes of the resultant copper nano... |
