AC electrical strength measurements on LDPE nanocomposites

An AC electrical strength test campaign was performed on different Low Density Polyethylene (LDPE) nanocomposites. Such materials were obtained by the dispersion of inorganic nanoparticles having different aspect ratio and surface nature: silica AEROSIL 200 and montmorillonite. All the considered nanofillers have been organically modified in order to obtain a good dispersion and an efficient interfacial interaction.. The investigated nanocomposite materials show a higher electrical strength than the pure LDPE.
