Comparison between Chemical Vapor Deposition and Flame Fragments Deposition Techniques for Synthesizing Carbon Nanotubes

Abstract

HR-TEM in order to make compare between the two types CNT/CVD and CNT/FFD. The HR-TEMs images showed that the two types were few walled carbon nanotubes FWCNTs with 0.6- 1.2 μm and 1.1- 2.7 μm in length for CNT/CVD and CNT/FL respectively. The outer and inner diameter were referred to thickness 2- 4 sheet of graphene for CNT/CVD while CNT/FFD was 2-3 sheets of graphene. The analysis indicates that Raman spectroscopy were influence with impurities when shows reduceing in the intensities of G, D and RBM bands.
