Carbon nanotubes (CNTs) can be combined with conducting polyaniline which exists in three idealized oxidation states, resulting with outstanding physical and chemical properties. The dual (granular and fibrillar) morphology polyaniline has been prepared through chemical oxidative polymerization method followed by mixing with different vol% of functionalized carbon nanotubes. These composites were prepared through simple and very efficient solution mixing method. The produced nano-composites have been characterized by different physiochemical techniques. For example, X-ray diffractometry, Fourier transform infrared spectroscopy, transmission electron microscopy and scanning electron microscopy. The prepared nanocomposites (0 to 21 vol% CNTs) express higher electrical conductivity compared to pure polyaniline due to the creation of conducting path between carbon nanotubes and polyaniline matrix. The electrical conductivity of prepared nano-composites with volume percent 3.3 and 13.9 of functionalized carbon nanotubes was 1.6 X 10-1 S/cm and 1.8 X 10-1 S/cm respectively.
