ABSTRACT: New and economic method of functionalized Multi walled Carbon Nanotubes (MWCNTs) was made using neem and flax (kitan) oil separately improving their solubility as compared with the traditional methods. This method is initiated by ultrasoniction mixture of each oil separately (neem and flax) with 0.05g MWCNTs. Then the samples were dried at 90°C in a vacuum oven for 24 h and annealing for 1h at temperature 200^oC to obtain the powder of MWCNTs containing functional groups treated with both oil separately. The results were examined by using Scanning Electron Microscopy (SEM) and Transmission Electron Microscopy (TEM) to study the morphology of the surface treated with neem and flax oil. Fourier transformed infrared spectroscopy (FTIR) shows the formation of functional group on to MWCNTs surface such as C=O and COOH. Furthermore, improving the antimicrobial activity of functionalized MWCNTs treated with oils and reducing colonies at high consecrations of samples against E. coli, P. aeruginosa and S. aureus after incubated for 24h which reveals the ability of functionalized MWNTs in removal pathogens and enhanced the adsorption of bacteria on the surface of (MWCNTs), which are used in environmental applications and contaminated water such as filters.
