Synthesis of hybrid functional nanocomposites (PPy-ZnO) was employed with ZnO by mechanical mixing method, this system, the observed FT-IR results ensured the presence of PPy in the composite and also pronounces the characteristic absorption peaks of ZnO around 591 and 438 cm−1. The observed strong vibration in the low wave number region around 591cm−1 is corresponds to antisymmetric vibrations of Zn-O-Zn bond of Zinc oxide. This ensured the presence of ZnO incorporated in the PPy nanoparticles. UV-Vis absorption spectra of PPy-ZnO nanocomposites helps to explore the optical behavior of incorporated nanoparticles into PPy matrix and hence, the integrated ZnO nanoparticles gives rise to the red shift of π–π* transition of polypyrrole. The XRD pattern exhibits the crystalline nature of PPy-ZnO nanocomposite and reveal out the existence of different crystallite sizes observed from diffraction peaks. Thermal stability of both polypyrrole and PPy-ZnO nanocomposite was investigated by thermo gravimetric analysis (TGA) and Differential scanning calorimetry (DSC). SEM images reveal that ZnO nanoparticles is deposited on the PPy surface which have a nucleus effect on the polymerization of PPy. It also ensures, the degree of deposition on the surface of PPy increases with ZnO content. SEM images indicated that the zinc particles are embedded in the PPy matrix forming the core-shell structure. ZnO nanoparticles exist as agglomerates due to high surface area and magneto dipole-dipole interactions between the particles. In SEM images, the black core is zinc particles with the diameter range of 50-150 nm and the light colored shell is attributed to PPy in the nanocomposites, which is due to the different electron penetrability. The EDAX results of PPy-ZnO reveals that an elements like Carbon (44.23 wt.%) and Sulfur (3.18 wt.%) molecules decreases and Zinc (23.47 wt.%), Oxygen(29.12 wt.%) molecules increases, while increasing concentration of ZnO nano metal oxide content.
