Dendrimer-assisted low-temperature growth of carbon nanotubes by plasma-enhanced chemical vapor deposition

摘要

Using a shielded growth approach and N_2-annealed,nearly monodispersed Fe_2O_3 nanoparticles synthesized by interden-dritic stabilization of Fe~(3+) species within fourth-generation poly(amidoamine) dendrimers,carbon nanotubes and nanofl-bers were successfully grown at low substrate temperatures (200-400 °C) by microwave plasma-enhanced chemical vapor deposition.
