â¢An attempt to find out application of Barium Ferrite & Graphite integrated with Polyaniline composite for electromagnetic Radiation Shielding.â¢Using and testing of composite materials shielding effectiveness instead of the other widely used materials.â¢Synthesis and Characterization of materials for its application as a shielding material.â¢Dielectric and Electromagnetic shielding behavior study of PANI/EG/BaFe12O19 composite.
Barium ferrite was incorporated into polyaniline matrix along with expanded graphite (EG) in order that the resultant conductive composite can be used for electromagnetic shielding. The different properties like complex permittivity (εâ²â²), permeability (μâ²â²), and effectiveness of shielding have been studied by vector network analyzer using theoretical enumeration given in Weir and Nicholson-Ross algorithms. The microwave absorption characteristic of the composites have been calculated in the X-band (8.2-12.4 GHz) frequency range which shows a shielding effectiveness up-to 37.1 dB, which strongly depends on dielectric loss.
