【摘要】：利用多孔氧化铝(AAO)模板经交流电沉积制备得到了铜纳米线阵列,扫描电子显微镜(SEM)、能谱仪(EDS)分析结果表明:其长度在1~2μm,直径在60~80nm之间。利用制备的铜纳米线催化生长了纳米碳纤维阵列(VACNFs),利用SEM对VACNFs的形貌进行了表征,结果表明,所制备的VACNFs呈现阵列状分布,每根纤维垂直基底直立生长,在纤维末端距离较近的纤维之间相互吸引缠绕形成纤维束。最后分析了纳米碳纤维阵列的生长机制并提出了生长模型。
[Abstract]:Copper nanowires array was prepared by alternating current electrodeposition of porous alumina (AAO) template. (EDS) analysis of scanning electron microscope (SEM), spectrometer showed that the length and diameter of copper nanowires were between 1 ~ 2 渭 m and between 60~80nm. Nano-carbon fiber arrays (VACNFs),) were prepared by using copper nanowires as catalyst. The morphology of VACNFs was characterized by SEM. The results showed that the prepared VACNFs exhibited array-like distribution, and the vertical substrate of each fiber grew upright. The fibers that are closer to the ends of the fibers attract each other to form a bundle of fibers. Finally, the growth mechanism of carbon fiber nanoarray was analyzed and the growth model was put forward.
