Nanoparticle incorporation in polymeric materials alters their inherent properties, such as dielectric constant and loss, hence affecting their application as dielectric materials. In the current study, three different oxide-based nanoparticles (Calcium carbonate, Aluminium and Titanium oxides) were added to polyvinylidene Flouride (PVDF) in the concentration of 0.5, 1.0, and 1.5%w/w for each nanoparticles to develop polymer nanocomposites in order to study the effect of such addition on the dielectric responses of PVDF over wide frequency range (20 Hz-2 MHz) using LCR digital frequency meter. The polymer nanocomposite samples were developed using a rapid roll-mix-milling and compression technique at 50°C. The addition of varying nanoparticles to the polymer matrix seems to have the same effects at rising Frequency on the relative permittivity, dielectric loss and conductivity. This suggests that it may be an interesting material for use in high-energy storage devices. A study of the structure and mechanical properties of the developed material is recommended for other potential application areas.
