Chemical Synthesis, Functionalization and Characterization of Multiwalled Carbon Nanotubes

Abstract

This research work is attempted to synthesize, functionalize and to characterize multi walled carbon nanotubes (MWCNTs). The synthesis of multi walled carbon nanotubes was done by chemical vapor deposition (CVD) method. The characterization of MWCNTs was done by adopting the following techniques such as field emission scanning electron microscope, X-ray diffraction, Fourier-transform infrared spectroscopy. The crystalline quality of MWCNTs was confirmed from the analysis of X-ray diffraction pattern. FE-SEM image obtained for MWCNTs and functionalized MWCNTs and it has been seen that dimeter of most of the MWCNTs lies around 90 nm, where as, functionalized MWCNTs diameter is smaller i.e., around 35 nm only. Fourier-transform infrared spectroscopy study confirmed the presence of –COOH and H- bonded –OH in functionalized MWCNTs.
