The nanocomposites of polypyrrole (PPy), single wall carbon nanotube (SWCNT) and polyvinyl alcohol (PVA) with different compositions were synthesized by the chemical oxidative polymerization and solution casting methods. The morphological and structural properties of the nanocomposites were investigated with the help of FTIR and SEM techniques. The Fourier transform infrared spectroscopy (FTIR) analysis showed that the addition of PPy/SWCNT nanocomposite into PVA created interaction within the composite structure. SEM images revealed that the incorporation of SWCNT significantly altered morphology of PPy and PVA. The PPy/SWCNT nanocomposites exhibit
an enhanced electrical conductivity 0.746 Scm-1 compared to 6.87 ×10-3 Scm-1 for pure PPy and 1.18 ×10-15 Scm-1 for neat PVA. However, the DCconductivity of PPy/SWCNT/PVA nanocomposite is found to drop a little giving a value of 2.44x10-4 S/cm-1. PVA has been selected as the matrix for PPy/SWCNT nanocomposite in order to give mechanical stability to the PPy/SWCNT nanocomposites. The tensile strength study suggests that the incorporation of PVA makes it possible to cast the mechanically stable conducting film of the PPy/SWCNT/PVA ternary composite.
