Abstract

In this paper the thermal and radiochemical behavior of nanocomposite materials consisting of isotactic polypropylene and various content of TiO2 (5, 10, 20 and 30 % w/w) are characterized. The contribution of nanofiller component is pointed out by the increase in oxidation induction time for the enhancing nanoparticles of titania. Although the radiation exposure decreases the thermal resistance of this kind of samples, the modification in activation energy corresponds to the ability of filler for the scavenging of radiolysis intermediates..
