Abstrakt: In this report, the Polypyrrole, PPy/Sn and PPy/SnO2 nanocomposites have been prepared through a facile chemical oxidation polymerization (COP) techniques. The resulting nanocomposites were characterized by Fourier transform-infrared spectroscopy (FT-IR), X-ray diffraction (XRD) and UV–Visible spectroscopy (UV–Vis). FTIR analysis confirms the presence of nano tin and SnO2 particles in the molecular structure. XRD patterns revealed that the sample is crystallite nature with tetragonal structure. The average crystallite size for the PPy/SnO2 and PPy/Sn nanocomposites are 27 and 56 nm. In addition to this, the surface morphologies and elemental compositions were investigated by field emission scanning electron microscopy (FESEM), high resolution transmission electron microscopy (HRTEM) and Energy-dispersive X-ray spectroscopy (EDX). We obtained the aggregate, hollow nanosphere for PPy/Sn nanocomposites. The results indicate that the hollow sphere of the nanocomposites effectively enhances the electrical conductivity.
