This paper focuses attention on the functionalization of multi wall carbon nanotubes (MWCNTs). It is important to disperse carbon nanotubes in organic and inorganic solvent, otherwise; the carbon nanotubes are aggregated and lost their efficiency. Functionalization of carbon nanotubes was carried out by chemical method. The Fourier transform infrared spectroscopy (FTIR) and Raman spectrum showed the functionalization of carbon nanotubes. A new peak was observed in around 1726 cm-1 as C=O stretch vibration in the carboxyl group (COOH). Scanning electron microscope (SEM) and Transmission electron microscope (TEM) observations showed that MWCNTs were dispersed effectively in aqueous solution.
