What is Synthesis of Bismuth Doped Cobalt Ferrite and Its Composite with Polyaniline about?

Ferrites are ceramics having Fe (III) ions. Cobalt ferrite was doped with bismuth via sol-gel method. The doped samples were mixed with polyaniline to form the composites. Polyaniline was chosen as it was a cheap material. Sol-gel method is a time saving and simple method. It also brings about the homogeneity in the reaction. The synthesized material was calcinated at 900 °C for 6 h. Preparation of polyaniline was done by oxidative polymerization method. Here ammonium persulphate act as an oxidative agent. The polyaniline was washed with methanol and dried for 24 h in an oven. The composite of bismuth doped cobalt ferrite and polyaniline were studied through X-ray diffraction (XRD), FTIR, UV, VSM and FESEM. It was observed that magnetic and optical properties changed with change in amount of dopant.
