ABSTRACT
Accepted: 14 September 2020
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.

1 Introduction A lot of studies have been completed about the research of ferrite particles due to their wide range uses in technical areas. Their common uses include as contrast agent in MRI, protein detection and drug delivery applications. They are considered best as capsules and receptors for drugs [1, 2]. These ferrite nanoparticles are joined with conducting polymers to achieve the nano-composites. Various researchers reported the investigated uses of such nano-composites [3]. The magnetic grains are lodged among

the non-magnetic matrix to produce soft ferrite system. Then the synthesized system is modified to attain desired consequences and make them suitable for particular application [4]. The properties such as elasticity and transparency were found in semi-crystalline substances like PVDF (polyvinylidene fluoride). Moreover, such a materials can be easily prepared and they possess sturdy piezo- and pyroelectric properties [5]. The polymers are combined with the ferrite nanoparticles to obtain nanocomposites. These nano-composites are widely applied in various instruments such as drug
