Preparation of polymeric hybrid nanocomposites based upon PE and silica

In this study is described the realization of nanocomposites based on a melt dispersion of nanoscopic silica particles in a polyethylene matrix. Different silane coupling agent were used to improve the interaction between nanosilica and polyethylene and then to improve the dispersion of the filler. In one case silane coupling agents containing vinyl groups 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. Were also detected mechanical properties, in a small punch test and wear resistance in a abrasimeter.
