摘要：

2 vol.-% TiO2 particles were incorporated into PET/PP blends with and without MA-grafted PP compatibilizer. During extrusion of the PET/PP/TiO2 composites the TiO2 particles migrated from the PP matrix to the PET-dispersed phase irrespective of the blending route. For the PET/PP/PP-g-MA/TiO2 composites, however, the location of TiO2 depended on the blending sequence. The preferred location of the TiO2 nanoparticles was confirmed by SEM pictures taken from the chemically etched surface of the blends. The observed migration behavior was traced to differences in the interfacial tensions between TiO2 and PET and TiO2 and PP, and to TiO2 encapsulation in one of the blend components during the related blending procedure.
