The microemulsion approach was used to create three new nano nanocomposites: Lead oxide (LO)/PbO, lead iron oxide (LIO)/PbO-Fe2O3 and lead iron oxide polypyrrole (LIOPYY)/PbO-Fe2O3-polypyrrole. X-ray diffraction (XRD), Raman, field emission scanning electron microscopy (FESEM), Brunauer–Emmett–Teller (BET) surface area, vibrating-sample magnetometer (VSM), and thermal gravimetric analysis were used to describe the nanocomposites (TGA). LO and LIO composites have an orthorhombic crystal structure, whereas LIOPYY nanocomposites have a monoclinic crystal structure, according to XRD studies. The Scherrer equation was used to calculate the crystallite size, which was a high value in LO and a low value in LIOPYY. A considerable shift in the composite structure was discovered using Raman analysis, confirming the formation of nanomaterials. The AC conductivity measurements revealed that LO has a lower conductivity than LIO, whereas LIOPYY has a greater conductivity. LIO exhibits higher Ms Values when measured using the VSM method.
