Abstract

Polyaniline was synthesized chemically in acidic medium in the presence of ammonium peroxydisulphate (APS) as oxidizing agent. PANI-ZnO nanocomposites prepared in the presence of various amount of nano ZnO (from 1 to 5 wt.%) by solution casting method, free standing film of polyaniline and its nano-composites was obtain by vaporization of solvent content. The composition, morphology and structure of the polymer and the nanocomposites were characterized by Fourier transform infrared spectroscopy FT-IR spectra, scanning electron microscopy (SEM) image and XRD pattern also thermal stability was studied by TGA analysis, electrical conductivity was measured by four point probe technique and mechanical properties were studied by tensile strength. The characteristic FTIR peaks of PANI were found to shift to lower number in nanocomposites due to formation of H-bonding. XRD results revealed that the crystallinity of PANI was more pronounced after addition of nano ZnO, while the intensity of the peaks increased by addition of ZnO nanoparticles. Also, TGA results showed that the decomposition of the nanocomposite was less than that of pure polyaniline which confirms the successful fabrication of products. Young’s modulus and strength at break point was increased in case of Nanocomposite, Addition electrical conductivity of the PANI–ZnO nanocomposite film was found to be smaller than that of the PANI film.
