Effects of inorganic nanofillers and combinations of them on the complex permittivity of epoxy-based composites

In this paper, we investigate the influence of nanofiller material and its concentration on dielectric properties of epoxy-based composite systems. A comparative study is performed between the unfilled base epoxy, the systems containing one type of nanoparticles (silicon dioxide, aluminum oxide or aluminum nitride) and composites containing a combination of two different fillers inside the host polymer.
