Dielectric Properties ZnFe2O4 Nanofiller on the Commercial Epoxy Composites

Abstract

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.
