摘要

Abstract

Nano-sized rod-like titanium dioxide (TiO

) filled rigid poly(vinyl chloride) (PVC) nanocomposites were prepared by using injection-molding method. Vicat

Charpy impact and tensile tests as well as thermogravimetric and dynamic mechanical analyses were used to characterize the structure and properties of the nanocomposites. The results showed that nano-TiO

could improve Vicat softening temperature and also improve thermal stability of PVC during the stages of dehydrochlorination and formation of carbonaceous conjugated polyene sequences

which can be ascribed to restriction of the nanoparticles on the segmental relaxation as being evidenced by raises in glass transition and

-relaxation temperatures of PVC upon filling TiO

. Addition of TiO

nanoparticles less than 40 phr (parts per hundreds of resin) could significantly improve impact strength of the composites while the TiO

agglomeration at high contents leads to a reduction in impact toughness.
