Enhancing Dielectric Properties through Nanocomposite Formation of Tripropylene Glycol Diacrylate and Montmorillonite"

Abstract

The study developed tripropylene glycol diacrylate/montmorillonite nano composites via in-situ physical cross-linking of TPGDA with different types of cationically exchanged montmorillonite. The cationic exchange was carried out using various chemical products as sources of cations. The synthesized nanocomposites were characterized by FTIR and XRD, and the dielectric properties of the TPGDA/MMt-Cs⁺ composite were studied over a high frequency range of 12 to 200 MHz and at a temperature range of 293-373 K. The results showed that adding TPGDA to the montmorillonite material improved the AC conductivity, dielectric constant, tangent loss, and dielectric loss when compared to montmorillonite without additives.
