during the last decades, there has been an increased interest in the synthesis of nanocomposite materials by introducing nanosized inorganic particles into polymers. To achieve
the positive effects of nanoparticles on properties, adequate dispersion of nanofillers within the polymeric matrix is required Different researches have been investigated the
different effects of nanoclay on the crystallization of PET matrix. It was found that the crystallization rate of nanocomposites could increase by the incorporation of inorganic nano
sized materials as a result of heterogeneous nucleation role of nanoparticles. In this study, the effect of anatase TiO2 on physical and thermo-mechanical properties of PET have
been investigated and the crystallization behavior of nanocomposite containing three different levels of the nanofiller have been discusse
