Synthesis of Highly Aligned Carbon Nanotubes in Liquid Phase

Abstract:

Aligned carbon nanotube arrays (CNTAs) were readily synthesized by a resistance heating method on a substrate of commercially available stainless steel which has more plentiful availability than the wafers of Si and quarts. The catalyst was supported on the substrate by dip coating with a methanol solution of M(C5H5)2(M=Co,Fe), and the substrate was electrically heated at 800oC in methanol. Highly aligned CNTAs were grown from the catalyst prepared from 0.02 M Co(C5H5)2 methanol solution. The alignment was influenced by the concentration and the kind of M(C5H5)2.
