In this study the realization of nanocomposites based on a melt dispersion of nanoscopic silica particles in a polyethylene matrix is described. Different silane coupling agents were used to improve the interaction between nanosilica and polyethylene and then to improve the dispersion of the filler. In one case vinyl groups-containing silane coupling agents containing were used. The nanocomposite obtained with this modifier was transformed in a crosslinked organic-inorganic hybrid after an electron beam radiation treatment. The nanocomposites and the hybrid were characterized with TEM and FTIR. The thermal decomposition was studied in TGA. Mechanical properties were also detected, in a small punch test and wear resistance in a rotative drum abrader. (C) 2009 Elsevier Ltd. All rights reserved.
