Year: 2025
Type: article
Abstract: In this study, the dielectric performances of PVA–BFO–PDB composite films are evaluated. The composites are synthesized by a solution casting technique. These composite material exhibits a significantly elevated dielectric constant and reduced dielectric loss. This composite material is synthesized by blending polyvinyl alcohol as the polymer matrix with bismuth ferrite (BFO) and polystyrene 2% divinylbenzene (PDB) as fillers. The dielectric characteristics of composite films consisting of PVA, BFO, and PDB are examined over a broad frequency range and varying weight percentages of PDB at room temperature. The PVA–BFO–PDB composite films show a high dielectric constant (≈91) with a dielectric loss factor of approximately <1 at 102 Hz when the PDB content is at 10 wt%. The synthesized PVA composites with improved dielectric performance find their application in potential energy storage devices.
