Synthesis and Characterization of Low Dielectric Polymer Composite: Ethylene-Propylene-Diene Terpolymer/ Barium hexa ferrite

Abstract

A series of organic- inorganic polymer composites were synthesized by incorporating Barium hexa ferrite (BHF) at different wt % in the Ethylene-propylene-diene terpolymer (EPDM) polymer matrix by adopting solution casting method. The synthesized EPDM/BHF polymer composite were characterized through different techniques i.e.; X-ray diffraction study, SEM(scanning electron microscope), dielectrical and electrical behavior in the frequency range 1 kHz to 1 MHz. A detailed study of the dielectric behavior i.e.; ε’ (dielectric permittivity), tan δ (dielectric loss), M’and M’’ (dielectric modulus) and σac (electrical conductivity) were reported in this communication. The XRD of the composites showed the uniform distribution of the filler particles in the polymer matrix. The SEM micrograph confirms the homogeneous dispersion and distribution of BHF particles in the EPDM polymer matrix. These polymer composite show a promising dielectric behavior which is different from its constituent components.
