| Abstract: | Poly(ethylene terephthalate) (PET)/TiO 2 nanocomposites were prepared by melt-blending PET and surface-treated TiO 2 . The crystallization behavior and the non-isothermal crystallization kinetics of these composites were investigated by differential scanning calorimetry (DSC). Jeziorny and Mo's methods were applied to describe the kinetics of the non-isothermal crystallization process. It was found that the PET matrix with incorporated surface-treated TiO 2 particles has lower crystallization temperature and melting point than that with incorporated pure nano-TiO 2 particles. Unlike plain TiO 2 , surface-treated TiO 2 particles showed less effect on the degree of crystallization of the PET matrix. |
