化学镀CuNiP-碳纳米管复合材料的制备与表征

Prepartion and characterization of chemical plating Cu - Ni - P onto carbon nanotubes

用化学镀的方法在多壁碳纳米管表面沉积Cu-Ni-P合金,制备碳纳米管复合材料． 并对制备出来的复合材料进行透射电子显微镜(TEM)和X-射线衍射(XRD)表征．通过XRD对已 制备的化学镀合金分析,得出沉积铜为立方面心结构而镍是非晶态．TEM观察复合碳纳米管,发现 在其表面沉积有分散均匀纳米级的金属颗粒,Cu-Ni-P合金呈球形．

Ni - Cu - P alloys have been deposited on the surface of carbon nanotubes （CNTs） through chemical plating techniques. Thus, composite nano- materials have been obtained. The composite materials obtained through chemical deposition have been characterized by transmission electron microscopy （TEM） and X - ray diffraction （XRD）. The alloys analyzed by XRD are made up of face - centered cubic （fee） Cu and amorphous Ni - P. The composite carbon nanotubes observed by TEM, alloy grains on the CNTs surfaces are uniform and nano- sized. Cu - Ni - P alloys are spheric.
