| Abstract: | This study examines the impact of SrFe₁₂O₁₉ nanoparticles on the structural, optical, and ferroelectric properties of PVDF-based nanocomposites. XRD and FTIR confirm a significant increase in β-phase content. UV-Vis spectroscopy reveals a redshift and peak broadening, enhancing light-harvesting and UV shielding. SEM images show uniform nanoparticle distribution, with higher concentrations forming wave-like patterns. Ferroelectric analysis via P-E loops demonstrates a rise in maximum polarization (Pmax) from 0.01 to 0.1 µC/cm², alongside increased remnant polarization (Pr) and coercive field (Ec). These enhancements are linked to β-phase promotion in PVDF. The findings suggest SrFe₁₂O₁₉/PVDF nanocomposites are promising for energy harvesting, sensors, actuators, and ferroelectric applications.
