C纳米管包裹的金属钴纳米线(管)同心电缆的制备与表征

The concentric cable of cobalt nanowires(nanotubes) encapsulated in carbon nanotubes has been prepared by using “ second order template” method, combined with electrodeposition. The products were characterized by SEM, TEM, XRD and Raman, respectively. The C/Co composite nanowires(nanotubes) were about 60μ m in length, and the thickness can be adjusted by changing the reaction conditions. This method could be extended to construct an array of multi layer nanotubes, composed of various metals, encapsulated in carbon nanotubes.

填充含能分子的碳纳米管有序阵列的构筑和表征

报导了黑索今填充的碳纳米管有序阵列的构筑。通过苯胺原位聚合在Al2O3模板的孔道内构筑了聚苯胺纳米管有序阵列，经高温裂解转化成碳纳米管，利用毛细凝聚作用将黑索今填装到碳纳米管中，得到黑索今纳米线填装的碳纳米管有序阵列。用TEM、SEM、XRD、FT-IR和^1H NMR作了表征。
