Dielectric Properties ZnFe2O4 Nanofiller on the Commercial Epoxy Composites

Epoxy is an eco-friendly polymer with excellent insulation properties that can be utilized to encapsulate and protect electronic components. In this analysis, the ZnFe2O4 nanoparticle was successfully synthesized by a simple physical method taking ZnO and Fe2O4 as precursors. The pure epoxy sheet was formed by the solution casting method and subsequently, nanocomposite sheets were produced. Fourier transform infrared of pure epoxy reveals the presence of polymeric groups and using a similar approach the other composite samples were analyzed. The spectrum of composite samples has a slight shift in the absorption band due to the ZnFe2O4 nanofiller. The dielectric loss, dielectric constant, and AC conductivity values show the influence of metal-based nanoparticle ZnFe2O4 incorporation compared to the pure sample and its activity corresponding to temperature and frequency. The results have proven that the prepared nanocomposite can accumulate electrical energy and can be utilized as a dielectric material.
