| 초록 | Aligned multi-wall carbon nanotubes (MWNTs) were synthesized through the catalytic decomposition of hydrocarbons in a quartz tube reactor. In this study, we investigated the influence of reaction parameters such as gas flow rate, ferrocene-xylene ratio and partial pressure, and reaction time on the yield and structure of vertically aligned carbon nanotubes produced by the floating catalyst method. The MWNTs produced had diameters in the range of 20∼100 nm, length around 100 μm and bulk density about 0.51 g/cm3 at a pressure of 10000 psi. It was possible to produce MWNTs with much faster growth rate of 12 μm/min than that reported previously by the increase of ferrocene-xylene partial pressure. |
