Synthesis And Characterization Of Cofe2o4 And Polypyrrole Based Composites

Abstract Spinel ferrites and polymer based nanocomposites are emerging as a new class of materials having potential for medical field and flexible electronic devices. Nano sized ferrites CoFe2O4 were synthesized via chemical technique called co-precipitation. The polypyrrole was produced via in-situ polymerization technique. The formation of nano-composites was completed by combining nano sized ferrites with polypyrrole. Electrical, magnetic and structural properties of samples were inspected through two probe method, vibrating sample magnetometer, and X-ray diffraction (XRD) technique respectively. The peak intensity of XRD was enhanced and its width reduced with rise of ferrite concentration in the nanocomposites. The dc resistivity was increased with the ferrite contents. The ferromagnetic behavior was picked through hysteresis loop. These parameters were optimized according to requirement by fixing the ferrites ratio. Samples PF-1 (25% ferrites) PF-2 (50% ferrite ratio) displays super paramagnetic phenomenon. These samples may be used in hyperthermia; a cancer treatment technique.
