为了获得性能优异的微电子材料,通过化学镀和自组装制备了平均直径小于50 nm的准一维金纳米复合导线.通过实验证实了金纳米线的形成机制,即纳米金复合导线是纳米金微粒在巯基化的碳纳米管表面通过自组装而形成的.碳纳米管分别依次与浓硝酸和浓硫酸的混酸(1:4)、LiAlH4、PBr3和NaHS反应,可得到活性基团巯基修饰的碳纳米管.分别用XPS、TEM、XRD等对实验结果进行了表征.

In order to obtain some noticeable microelectronic materials, the quasi-one-dimensional gold nanowires with average diameters less than 50 nm were prepared by electroless and gold nano-particles self-assembling. The forming mechanism of gold nanowires was proposed, the gold nanowires could be prepared by the gold nano-particles self-assembling on the surface of carbon nanotubes (CNTs) at the presence of mercapto groups (-SH). The carbon nanotubes modified by mercapto groups were prepared by reacting with the mixed acid solution of HNO3 and H2SO4, LiAlH4, PBr3, NaHS in turn. The active mercapto groups inarched onto the surface of carbon nanotubes were also demonstrated by XPS analysis. The microstructure of gold nanowires was analyzed by TEM images and XRD pattern.
