Ramajo, L. | Castro, M. S. | Reboredo, M. M.
Dielectric properties and relaxation phenomena of hybrid material (functionalized nanosilver/BaTiO₃/epoxy) were studied as a function of ceramic content. Nanoparticles were obtained through chemical reduction in ethanol and triethylenetetramine. Epoxy resin, functionalized Ag and BaTiO₃ were mixed and composites were prepared onto glass substrates by dipping technique. Samples containing various amounts of ceramic filler were examined by thermal and SEM analysis. Dielectric measurements were performed at different frequencies and temperatures. It was found that hybrid materials had high permittivities and their relaxation processes were influenced by the epoxy resin near its Tg, while metallic and ceramic content modified the real permittivity values.
