Effects of curing and filler dispersion methods on dielectric properties of epoxy nanocomposites

Effects of the differences in the curing agent and filler dispersion method on the dielectric properties were examined for epoxy/clay nanocomposites. Measurements of permittivity, conductivity, and space charge distribution suggest that the curing agent gives a strong effect and the presence of nanofillers affects secondly, while the filler dispersion method gives a weak effect.
