Magnetic Properties of Hybrid Inorganic-organic Flexible Nanofibers

Polypyrrole nanofibers (PPy-NFs) had prepared via chemical oxidation of pyrrole monomer by Iron (III) chloride in the presence of methyl orange. As well as, Nanomagnetic particles of Co0.8Mn0.2Fe2O4 and Zn0.8Mn0.2Fe2O4 had synthesized by the hydrothermal autoclave reactor after use co-precipitation technique. The PPy-NFs nanocomposite that obtained from decorating of PPy-NFs with Nanomagnetic particles. The XRD studied showed that the (PPy-NFs) is non-crystalline and the average crystallite size of Co0.8Mn0.2Fe2O4 and Zn0.8Mn0.2Fe2O4 were 8.54 and 14.47 nm respectively. These two belong to single phase cubic spinel. FESEM studies exhibit that PPy has a nanofibers structure with distinct diameters and most the magnetic nanoparticles had homogeneous distribution and had sphere form. The saturation magnetization (Ms) increased with increasing ferrite content in the nanocomposite samples, according to magnetic hysteresis loop measurements. As its increases in pure ferrite samples by increases cobalt ions. The Ms Values of Co0.8Mn0.2Fe2O4, Zn0.8Mn0.2Fe2O4 and PPy-NFs were 41.15 emu/g, 10.13 emu/g and 14.95 emu/g respectively.
