Various epoxy-based samples were prepared with different content of micro- and nanosized silica filer. In the case of a constant %-weight content of filler amounting to 65%, the microphase was replaced by a nanophase consisting of 2.5% and 5% weight. Three research teams used dielectric spectroscopy to compare the dielectric behaviour of the different composites. Microstructure analyses of the various...
Material samples were prepared consisting of silica particles in an epoxy matrix. The generic compound contained a large amount of micrometric silica (e.g. 60% wt.) and a few % of nanosilica. Investigation of the microstructure of the samples showed that indeed the microcomposites exhibited a nanostructured morphology. Dielectric spectroscopy was used to compare the behavior of materials differing...
