Carbon nanotube (CNT) is one of the most attractive nanomaterials which may be used in many potential applications of nanotechnology due to its excellent mechanical, electrical and thermal properties. We demonstrated the fabrication of carbon nanotube at the surface of anodic aluminum oxide (AAO) membrane by chemical vapor deposition (CVD) method. Acetylene was used as a hydrocarbon source and Fe as catalyst. CNT was synthesized at different temperature. The iron catalyst was confined in the holes of the AAO membrane. A variety of carbon structures such as nanotubes, helices, spiral, and hook-like curved shapes in the range of micrometer were synthesized. High graphitic multiwall carbon nanotube (MWCNT) was found at 700-750°C temperature.

Carbon nanotube (CNT) is one of the most attractive materials for the potential applications of nanotechnology due to its excellent mechanical, thermal, electrical and optical properties. We demonstrated the fabrication of carbon nanotube and carbon nanofiber (CNF) inside the pore and at the surface of anodic aluminum oxide (AAO) membrane by chemical vapor deposition method at atmospheric pressure. Ethanol was used as a hydrocarbon source and Co–Mo as catalyst. CNT was synthesized at different temperature. High graphitic multiwall carbon nanotube (MWCNT) was found at 750°C, while CNF was found at 800°C and above temperature analyzing by Raman spectroscopy.

Potential Applications

Ordered nanostructure materials have received attention due to their unique physical properties and potential applications in electronics, mechanics and optical devices. To actualize most of the proposed applications, it is quite important to obtain highly ordered nanostructure arrays. The well-aligned nanostructure can be achieved by synthesizing nanostructure material in the highly ordered template. In this paper, Anodic Aluminum Oxide (AAO) templates were fabricated using a two-step anodization process with pretreatment such as electropolishing and annealing. To reduce process time and get well-aligned pore array, rapid thermal anneal by an IR lamp was employed in vacuum state at 500oC for 2 hours. The pore array is comparable to a template annealed in vacuum furnace at 500oC for 30 hours. The well-fabricated AAO template has a mean pore diameter of 70 nm and the interpore distance of 100nm. The pore density can be as high as 1.2×1010cm-2.
