Abstract

A new carbon network is prepared using microwave plasma enhanced chemical vapor deposition(MPCVD) under the plasma of a mixture of methane, hydrogen and nitrogen at 720 °C. The Field Emission Scanning Electronic Microscopy(FESEM) images show that the carbon nanotubes are self-organized into carbon networks, which is different from the previously reported carbon nanotube ropes or nanofibers. The carbon networks are about 1 micron in diameter, more than 10 microns in length and composed of hundreds of carbon nanotubes with the diameter from 20 to 100 nm. Energy Dispersive X-Ray(EDX) results confirm that the network is carbon in nature, with a small amount of Ni which was used as catalyst.
