Abstract

silver-epoxy nanocomposite films based on diepoxide of Mn = 450, silver tetradecanoate and triethylamine were synthesized by in situ method. The mean diameter of AgNPs in nanocomposite films as defined by SEM technique has been found within the range of 15–20 nm. Ag NPs narrow size distribution was found independent on silver tetradecanoate concentration as shown by UV-vis spectroscopy analysis. Dielectric properties of silver-epoxy nanocomposite films were investigated also by Broadband dielectric spectroscopy technique.
