Investigation of microwave attenuation and shielding performance of PTFE/Fe2O3/OPEFB composites at X-band frequency
This study explored the microwave attenuation and shielding properties of PTFE/Fe2O3/OPEFB composites in the X-band frequency range. Fe2O3 nanoparticles were incorporated into the PTFE/OPEFB matrix using a powder-dry mixing technique. The composites were characterized using XRD and FESEM, and attenuation performance was evaluated using a VNA. The results indicated that the addition of Fe2O3 nanoparticles improved microwave attenuation and shielding properties, with the composite containing 15 wt% Fe2O3 exhibiting the highest attenuation of 16.02 dB. The homogeneous dispersion of Fe2O3 nanoparticles was confirmed through FESEM analysis, and XRD analysis confirmed the presence of Fe2O3 nanoparticles in the composites. The study concludes that PTFE/ Fe2O3/OPEFB composites have potential for electromagnetic interference shielding applications in aerospace, telecommunications, and electronics industries.
