Magnetic behavior of ferrite-polymer composites for hyperthermia applications

Journal Article

The current research is related to the preparation and inspection of various
properties of nano-composites. These composites are the combination of ferrite
filler and polypyrrole matrix. The co-precipitation route was taken into account
to produce ferrite filler and eminent in-situ polymerization method was utilized
to obtain polypyrrole. Merging of Nd0.04Fe2O4 ferrites within the polypyrrole
polymeric matrix enabled to get nano-composites. There were six samples PPy
(polypyrrole), FP1 (25% ferrite), FP2 (50% ferrite), FP3 (75% ferrite, FP4 (100%
ferrite) and pure ferrite. The structural, morphological and magnetic behaviors
of the fabricated samples were examined. The ferromagnetic behavior of fabricated
composites was witnessed through hysteresis loop. When the quantity of
ferrite filler was increased in the matrix, the variation in the magnetic parameters
(magnetization and coercivity) resulted. The high values of dielectric
constant suggest that these samples may be suitable for microwave devices.
