In this study, (Ta0.1Sm0.9)0.04Ti0.96O2 /Polyvinylidene fluoride composites were synthesized and analyzed for colossal dielectric properties. The ceramic powder was prepared by solid-state ceramic route, confirmed its phase purity through an X-ray diffractometer, and composites with different volume fractions were synthesized by finely dispersing the filler in the Polyvinylidene fluoride (PVDF) matrix followed by compression molding. Dielectric properties (dielectric constant and loss) up to 1 MHz were studied using an impedance analyzer. A high dielectric constant of 45 along with an acceptable loss of 0.089 was obtained for an optimum filler volume of 50% at 1 kHz. Hence the composites can be effectively used for energy storage applications.<br>
