Abstract :
In this paper, we present an investigation of the dielectric properties of epoxy based nanocomposites filled with silica. Epoxy nanocomposites with surface modified nanoparticles were ex-situ synthesized using a special mixing device called nanomizer. The DC breakdown characterization of the samples filled with 0.2 vol.%, 0.5 vol.% and 1.0 vol.% showed an increase of the DC breakdown strength compared to the neat epoxy. The highest breakdown strength was observed for the samples with 0.5 vol.% fill grade. Tentative explanations are provided for the experimental results.
