Abstract: To obtain high energy density with low dielectric loss, we synthesized polymer/ceramic composite by incorporating the giant dielectric constant material [Ba0.95Sr0.05(Fe0.5Nb0.5)O3] in a poly(vinylidene fluoride) (PVDF) polymer matrix. X-ray diffraction analysis confirmed the single phase monoclinic structure in all the composite samples. Microstructural analysis indicates that the Ba0.95Sr0.05(Fe0.5Nb0.5)O3 ceramics are evenly distributed in the PVDF matrix in all the composition. The high dielectric constant (~4045) with low dielectric loss (~0.06) was obtained for 10 wt% PVDF content in composite at room temperature. We found high energy density (3.02 J/cm3) for 10 wt% PVDF content in composite at room temperature. These results may be exploited in the development of high energy density capacitors. A significant variation of dielectric constant with magnetic field was noticed, which was not reported previously. © 2015, Springer Science+Business Media New York.
