In this work the photo-oxidative behavior of neat polypropylene (PP) and PP based nanocomposites incorporating graphene nanoplatelets (GnP) was studied.

The photo-oxidation has been followed by monitoring the change of the rheological, mechanical and spectroscopic properties upon artificial exposure to UV-B light. The results revealed that the presence of GnP reduced the rate of photooxidation of the PP matrix and, in the investigated composition range, the photo-stabilizing action improved with increasing the GnP content.

Abstract
In this work the photo-oxidative behavior of neat polypropylene (PP) and PP based nanocomposites incorporating graphene nanoplatelets (GnP) was studied. In particular, the influence of the amount of incorporated GnP was evaluated. The photo-oxidation has been followed by monitoring the change of the rheological, mechanical and spectroscopic properties upon artificial exposure to UV-B light. The results revealed that the presence of GnP reduced the rate of photooxidation of the PP matrix and, in the investigated composition range, the photo-stabilizing action improved with increasing the GnP content.File | Dimensione | Formato | |
