Synthesis and Characterization of PANI and Polyaniline/Multi Walled Carbon Nanotube Composite

ABSTRACT The study reports the synthesis of doped polyaniline (PANI) with multi-walled carbon nanotube (MWCNT) composites. These composites have been characterized by atomic force microscopic (AFM) and Fourier Transformer- Infra Red (FT-IR) to study the contribution of MWCNT on the morphology and the structure of polyaniline. The AFM studies distributed morphology of MWCNT in these composite films, the surface roughness was seems to increase with increasing the amount of MWCNT. FTIR investigations show the formation of MWCNT doped composite at the molecular level and their interaction with PANI can be attributed to charge transfer. The nanocomposites showed increased conductivity by increasing the frequency and MWCNT amount. S the exponential factor was more than unity. Real and imaginary parts of dielectric constant were decreased with increasing frequency which can be attributed to the powr-low behavior know at low frequency dispersion.
