Synthesis, characterization, and dielectric spectroscopy of TiO₂ and ZnO nanoparticle-reinforced epoxy composites

Epoxy nanocomposites exhibit remarkable characteristics by synergistically integrating the characteristics of epoxy resin with the unique properties of nanoparticles. This study focuses on the incorporation of ZnO and TiO₂ nanoparticles into epoxy composites and investigates their impact on dielectric properties. A three-dimensional crosslinked structure was formed using Bisphenol-A epoxy resin and amine hardener. Dielectric spectroscopic assessments of the nanoparticle-doped epoxy composites were conducted over a frequency range of 20 Hz to 2 MHz and extended to 200 MHz to 20 GHz. The research provides a detailed analysis of the influence of ZnO and TiO₂ nanoparticles on pristine, undoped epoxy resin. We present Regression analysis which is a useful tool for predicting the dielectric constant of intermediate frequency because it can save time and resources. Experiment data from tests show that using the XGBoost regression analysis can result in a 60% reduction in both time and resource requirements.
