Studies on Crystallizations and Mechanical Properties of Polypropylene/Nano-TiO₂ Composites

Abstract:

The surface features of modified nano-TiO₂ were characterized by FI-TR. PP/nano-TiO₂ composites were prepared via melt blending. The mechanical properties and crystallization were analyzed by mechanical properties tests, DSC and POM. The results show that filling nano-TiO₂ to PP matrix result in the improvements of impact and tensile strength at the same time, and nano-TiO₂ plays a role of heterogeneous nucleation so that crystallization grain can be refined, crystallinity and crystallization speed of PP are increased.
