N2 - This work has investigated the electromagnetic interference shielding effectiveness (EMI-SE) of Mn–Zn–ferrite–Poly(vinylidene fluoride) (MZF-PVDF) composites in the microwave/GHz frequency range. The modulation of EMI-SE of MZF-PVDF composite structures was observed due to the variation of MZF nanofillers weight percentage inside the matrix of PVDF. The polycrystalline phase of MZF-PVDF composite structures was identified by X-ray diffraction (XRD) analysis. The presence of polar β-phase of PVDF matrix in the MZF-PVDF composite structures was observed and estimated by the FTIR analysis. The variation of magnetization as a function of applied magnetic field shows a maximum magnetization of 15.8 emu/g of MZF-PVDF composite materials, whereas the variation of dielectric permittivity due to the formation of MZF-PVDF interfaces inside PVDF matrix was observed in the frequency dependent dielectric response study. The high value of SE of nearly −32 dB at a matching frequency of 11.5 and 14 GHz has been observed for MZF-PVDF composites and this high SE of MZF-PVDF composites makes them most efficient candidate for the fabrication of lightweight, flexible, laminated electromagnetic pollution reducer (EPR).
