The Effect of Temperature on Properties of CNTs Grown by Chemical Vapor Deposition

Abstract

In this article, the carbon nanotubes (CNTs) grown at different temperature by thermal chemical vapor deposition(T-CVD) have been reported, while the effect of growing temperature and catalyst annealing on the quality of CNTs has also been investigated. The longest CNT bundles were grown at the temperature of 730°C by Scanning Electron Microscopy (SEM) images and the better quality of CNT bundles were achieved at higher temperatures of 850°C by Raman spectroscopy.
