In this article, we have synthesized the Polypyrrole/Ba0.6Sr0.4Fe12O19 (PBSF) composite via in-situ polymerization technique. The synthesized samples were further characterized for structural, electrical, magnetic and microwave absorbing characterizations. The X-ray diffraction patterns reveal the formation of pure hexagonal ferrite phase whereas the Fourier transform infrared spectrums and X-ray photoelectron spectroscopy confirms the formation of polypyrrole/BSF composite structure. The microwave absorbing and shielding properties were studied in the frequency range 8–18 GHz. Using X and Ku band. The magnetic properties were studied using VSM and the PBSF37 composite shows the highest magnetic moment 59.58 emu/gm rather than the other PBSF composites and pure BSF ferrite. The PBSF37 shows the maximum microwave absorption of 89% over the broadband frequency range 8–18 GHz. The maximum shielding effectiveness 37.49 dB at 15.2 GHz corresponding maximum microwave properties were also observed for the same sample.
