Kinetics of growth of carbon nanotubes

Kinetics of growth of carbon nanotubes is important for applications of material in construction field. Here I discuss the kinetics of growth of carbon nanotubes inside metallocene-filled single-walled carbon nanotubes (SWCNTs). The growth mechanism of carbon nanotubes is revealed [1]. It includes stages of growth on carbide and metallic catalyst particles [2]. Two stages are characterized with growth rates and activation energies [3]. They are dependent on diameter and metal type. The growth rates increase with decreasing the nanotube diameter [4]. The activation energies also depend on diameter. They also show slight dependence on chiral angle of carbon nanotube. The metal dependence is caused by different structures of catalyst particles with different diameters. These findings are very important for construction of buildings of the future.
