During the first step of the reaction, Cl and CHCl2 groups were attached to the surfaces of MWCNTs through an electrophilic addition reaction. In the second step of process, Cl atoms were replaced with NH2 and amino groups (ethylene diamine and butyl amine) under a nucleophilic substitution reaction. The aminated MWCNTs have high solubility and dispersion stability in organic solvents and polymeric matrixes. FTIR, XRD, TGA and Raman spectroscopy were used for characterization of the achieved products. The analysis results indicate that the MWCNTs functionalized with high concentration of amino groups. Also, treated CNTs show good dispersity and interfacial compatibility when used to make MWCNT/polymer composites. Proposed method is an efficient route to introduce of amino groups onto the surfaces of MWCNTs and the process is a very effective, clean, safe and easy to operate, and the scale up of this method is easy. %U https://www.ijnnonline.net/article_13472_09c49cab80d7a8d55ac234c5add3ddf5.pdf
