- Abstract
The article examines how the crystallization behavior of high molecular weight poly(ethylene terephthalate) (PET) is affected by organoclay and polyhedral oligomeric silsesquioxanes (POSS) in terms of nanoparticle content and shear rate. The nanoparticles served as nucleating agents for PET; they also increased the cold crystallization temperature. Clay proved to be more effective than POSS, giving the highest crystallization rate of all the PET nanocomposites examined. As in differential scanning calorimetry (DSC) measurements, clay appeared to more effectively promote crystallization under shear.
