Facile Synthesis of Long, Straight and Uniform Copper Nanowires via a Solvothermal Method

Keywords： copper

Copper nanowires were facilely prepared via a solvothermal method. In this method, cetyltrimethylammonium bromide (CTAB) was used as a soft template, copper nitrate was an inorganic precursor, and absolute ethanol served as a reducing agent as well as a solvent. X-ray diffraction (XRD) and scanning electron microscopy (SEM) were used to characterize the as-prepared copper nanowires. The as-prepared copper nanowires are fairly uniform and long. The majority of them are longer than 100 μm and some even longer than 200 μm. Furthermore, most nanowires are quite straight. In addition,The mechanism of the growth process of copper nanowires was discussed.
