Dielectric, Ferroelectric, and Energy Storage Properties of Solvent Casted P(VDF-TrFE) Film
This study investigates the effects of hot-pressing temperatures on the dielectric, ferroelectric, and energy storage properties of solvent-casted Poly (vinylidene fluoride-trifluoroethylene) (PVDF-TrFE) films. The hot-pressing process enhances the crystallinity and alignment of polymer chains, directly affecting their electrical properties. The aim is to optimize the performance of PVDF-TrFE films for potential energy storage devices. X-ray diffraction (XRD) and Fourier transform infrared (FTIR) analysis were used to investigate phase formation and the fraction of β-phase. The presence of the β-fraction inside the copolymer is crucial for multifunctional applications. The scanning electron microscopy (SEM) analysis verified the uniform and glossy surface of the P(VDF-TrFE) film. The dielectric, ferroelectric, and piezoelectric properties were found suitable for energy storage and harvesting applications. The remnant polarisation (Pr) and coercive field (Ec) in the ferroelectric hysteresis loop were affected by β-fraction and crystallinity.
