Abstract

Carbon nanotubes were synthesized with a microwave plasma chemical vapor deposition method using nickel as catalyst. A gas mixture of methane and hydrogen was used. The alignment and length of the synthesized nanotubes were studied with Scanning Electron Microscope (SEM). With a specially designed process, we obtained dense and vertically aligned nanotubes with length up to 250 micrometers within 20 minutes of growth at temperatures between 650°C and 700°C. The diameters of the nanotubes are in the range of 40 to 70nm, determined with Transmission Electron Microscope (TEM). The nanotubes that we synthesized are not completely hollow and are separated into many nano-compartments by curved platelets. The very large aspect ratio (length/diameter) and the fine alignment of the cluster nanotubes are the important features of our process. These features are expected to be very beneficial for applications such as polymer reinforcement.
