In the present research, aligned carbon nanotubes were synthesized by thermal chemical vapor deposition using acetylene as the source gas and iron as the catalyst. The overall appearance and nature of the aligned carbon nanotube are affected by different variables in the process such as the concentration of the catalyst, the operation temperature, the flow rate of the carrier or reaction gas, the reaction time, the pre-treatment, et cetera. Microstructural analyses were done by atomic force microscope, field emission scanning electron microscope and high resolution transmission electron microscope. Growth of aligned carbon nanotube with optimal microstructure was observed when the catalyst concentration was controlled at 0.02M, temperature at 775 degrees Celsius, acetylene flow rate at 2.5 seem, and a reaction time at 5 minutes. |
