The nature of the functional groups on the filler surface is one of the key influences on the interfacial interaction in the aging of polymer composites. However, the characteristics of this interfacial effect and its relation with functional groups remain unclear. In this study, we investigated the effects of interfacial interactions on the photooxidative aging of silica-filled polypropylene (PP) composites in which the interfaces comprise functional groups possessing different photooxidative properties. Results showed that the effects of interfacial interactions on the photooxidative aging of the silica-filled PP composites were closely related to the composition of the interfacial functional groups. Since the effect of interfacial interactions on the PP oxidation rate was correlated with the concentration of the interfacial functional groups, an aging kinetic model of interfacial effects could be constructed for determining the role of interfacial functional groups in the photooxidative aging of PP composites. This study will provide new ideas for developing interfacial antioxidant strategies for polymer composites.
