Abstract:
The effects of silver nanoparticle on the physical properties of syndiotactic polypropylene (sPP) were investigated in terms of rheological responses and crystallization behavior under shear. Silver nanoparticle played as the nucleating agent of sPP by increasing crystallization temperature (Tc) and heat of crystallization (ΔHc). The introduction of silver nanoparticles more than 1 wt% brought about the rise of dynamic viscosity when compared to pure sPP. sPP with 5 wt% silver nanoparticle exhibited the higher tan δ and lower relaxation time than the others in the low frequency range. However, the effects of silver nanoparticle on the rheological properties became less noticeable when the loading level was higher than 5 wt%.
