In this study Multi Walled Carbon Nanotubes (MWCNTs) were functionalized by amine group and Polyaniline nanocomposites with functionalized MWCNTs were prepared by ex-situ method. The amine functionalized MWCNTs (am-CNTs) were simply and efficiently blended ultrasonically in the Isopropyl Alcohol solution of polyaniline emeraldine base (PANIEB). Results show the characterization of am-CNTs/PANIEB nanocomposites as a function of different am-CNTs concentrations by weight. The structure and morphology of the composites were characterized by scanning electron microscopy; Transmission electron microscopy and Fourier transform infrared spectroscopy.
