| Summary: | This study delineates the process of fabricating and the results of investigating the dielectric properties of hybrid particles created through the integration of Poly(vinylidene fluoride) (PVDF) filled with RuO _2 coated on BaTiO _3 nanoparticles ( n BT), designated as RuO _2 – n BT. These hybrid particles were successfully synthesized employing a simple and cost – effective solid – state reaction method. The inclusion of RuO _2 – n BT in the PVDF matrix engendered a notable enhancement in its dielectric properties. Notably, a RuO _2 – n BT fraction of 0.5 manifested a dielectric constant ( ε ′) of 107.4 and a dielectric loss tangent (tan δ ) value of 0.062 at 30 °C and 1 kHz. These findings signify the effective role of interfacial polarization occurring between the PVDF matrix and the RuO _2 – n BT hybrid particles, leading to a marked improvement in dielectric attributes. Moreover, the observed low tan δ value indicates the elimination of conductive pathways, an inhibitory effect attributed to the incorporation of RuO _2 – n BT hybrid particles. This study underscores the promising potential of RuO _2 – n BT hybrid particles in fine – tuning and augmenting the dielectric properties of polymer composites, particularly in scenarios necessitating low tan δ and high ε ′ values.
