Crystallinity of Polyethylene Terephathale/TiO2 Nanocomposites

Nanocomposites of PET/TiO2 has been prepared and their relative crystalinity behavior has been studied. Using a micro twin-screw extruder, nanocomposites incorporating low percentage of the filler has been melt blended in same conditions. Differential scanning calorimetry (DSC) has been used to characterize crystalinity behavior of the samples. Results showed that all nanocomposites have increased crystalinity content as well as crystalinity temperature. Based on increased crystalinity speed, nucleating effect of the fillers is probable
