Abstract

Novel PbO- Fe3O4-polypyrrole Nanocomposites were synthesized by two techniques including sol-gel and sonication. The nanocomposites were described using Raman spectroscopy, X-ray diffraction (XRD), field emission scanning electron microscopy (FESEM), vibrating-sample magnetometer (VSM), conductivity measurements, and thermal gravimetric analysis (TGA). According to XRD phase identification, the crystal structure of lead oxide was orthorhombic in both techniques, lead iron oxide was orthorhombic according to the sol-gel in comparison with sonication, which was monoclinic, while the crystal structure of lead iron oxide /polypyrrole nanocomposites was monoclinic in both techniques. The crystallite size was calculated using the Scherrer equation, which was lowered from lead oxide to lead iron oxide/polypyrrole. Raman’s research revealed a significant change in the composite structure, indicating the creation of nanomaterials. According to the AC conductivity measurements, lead oxide had a lower conductivity than lead iron oxide, while lead iron oxide /polypyrrole had a higher conductivity. When assessed using the VSM technique, lead iron oxide had higher Ms values.
