A new method of amidation of Carboxy Multi Walled Carbon Nanotubes (MWCNT-COOH) with diamine monomer such as ethylene diamine (EDA) and O-Phenylenediamine (OPDA) was applied by using a solution blending technique. The structure and properties of these composites have been investigated by FTIR, SEM, TEM, XRD, UV, DSC and TGA. The formation of Poly [MWCNT/ Amide] composites was confirmed and the DC electrical conductivity of poly-composites was in the range 4.5×10^-6-5.3×10^-6 S/cm due to the interaction between the nanotubes.
