“…The BHF sample contained 90.91% of BaFe12O19 and 7.086% of F2O3 as impurity with sig value 1.9. The sample exhibited hexagonal structure with lattice parameter a=b=5.8950334 Å and c=23.21821 Å [5]. Fig 1(c) indicates the XRD diffraction of the polymer composite films at different wt% of the BHF.…”

“…EPDM (Ethylene propylene diene terpolymer) and Cyclohexane (%) were purchased from LOBA chemicals. The filler barium hexa ferrite (BHF) Nano particles was previously prepared by using Sol gel combustion method via urea root [5].EPDM/BHF Nano composites were prepared by adopting solution casting method. First the EPDM rubber was completely dissolved with cyclohexane through magnetic stirrer.…”

“…It can widely use as permanent magnet, in high density recording application and magneto optical devices. [5] Research on EPDM composites have been carried out by many authors. Ali et al investigated that the thermal and mechanical behavior of EPDM matrix increases with silica loading and it possess insulating properties which is helps them in high voltage insulation application.…”

“…The electrical behavior of the polymer of the composite depends upon the polymer matrix, filler added, dispersion of filler in the polymer, frequency and temperature [5]. This work was devoted to studying the dielectric and electric behavior of EPDM / BHF composites at wide frequency range (1 kHz to 1 MHz) at different temperature.…”

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.
