synthesis of new pbo-fe2o3-polypyrrole hybrid nanocomposite to improve the structural, magnetic and electrical characteristics of lead oxide

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.
