AB  - Poly(vinylidene fluoride) (PVDF) composite films filled with lead-free Ba0.8Ca0.2(Zr0.1Ti0.9)O₃ (BCZT) were prepared by solution casting, using ceramic powder made by solid-state reaction. From the weighed masses, the dry films contain 9–50 wt.% BCZT. X-ray diffraction shows semi-crystalline PVDF together with crystalline perovskite BCZT. At room temperature the relative permittivity falls with frequency for every composition and does not change monotonically with ceramic fraction. The 37.5 wt.% film has the largest permittivity, dropping from about 11.5 at the low-frequency end of the sweep to 8.2 at 5 MHz, with tan δ between 0.08 and 0.13. Polarization–electric-field (P–E) loops measured at a common field of 100 kV cm⁻¹ are slim and unsaturated; at this field the 37.5 wt.% film gives the largest maximum polarization (0.25 μC cm⁻²) and recoverable energy density (0.0106 J cm⁻³), and the efficiency is 79–83% up to 37.5 wt.% and 70% at 50 wt.%. At the highest field recorded for each film, the 9 wt.% film reaches W_rec = 0.145 J cm⁻³ at 700 kV cm⁻¹, and among these maximum-field loops the 28.6 wt.% film has the highest efficiency, 73.9% at 300 kV cm⁻¹. Since the maximum field differs from film to film, the maximum-field values are reported as loop-specific results and not as a ranking of compositions.
