Abstract
Iron-decorated polypyrrole-stannic oxide (Fe-PPy-SnO2) nanocomposites were prepared by in situ polymerization. The structural characteristics, morphology, and uniform distribution of SnO2 nanoparticles in iron-decorated PPy-SnO2 nanocomposites were studied by using x-ray diffraction (XRD), scanning electron microscopy (SEM), Fourier-transfer infrared (FTIR) spectroscopy, transmission electron microscopy (TEM), etc. Also, AC and DC electrical conductivity and electromagnetic shielding interference (EMI) properties were performed. The results revealed that the conductivity increases with a decrease in weight % of SnO2 nanoparticles. It has also been observed that, from 303 K to 378 K, DC conductivity is marginally increased by the increase in temperature. The Fe- PPy-5% SnO2 sample exhibited a marginally lower resistance than that of other composites. The dielectric constant value decreases with the increase in frequency, and the maximum dielectric constant was observed for Fe-PPy-5% SnO2 and the lowest for Fe-PPy-25% SnO2. The Fe-PPy-5% SnO2 sample showed the highest shielding effectiveness as compared to other composites in the frequency range 2–3 GHz. The experimental results show that the materials exhibit useful properties, i.e., EMI shielding properties, and could be developed for different operations in electronic, electrical, and EMI shielding applications.
