Large-Scale Synthesis of Perpendicularly Aligned Helical Carbon Nanotubes

Abstract

Large-scale perpendicularly aligned helical carbon nanotube arrays were prepared by co-pyrolysis of Fe(CO)₅ and pyridine onto the pristine quartz glass plates in a tube furnace at 900−1100 °C under a mixture flow of Ar and H₂. The resultant aligned helical carbon nanotubes could not only facilitate the structure−property characterization for helical carbon nanotubes but also allow them to be effectively incorporated into devices for practical applications.
