Synthesis and Characterization of Poly(Ethylene Terephthalate) /Al2O3 Nanocomposites

Poly (ethylene terephthalate)(PET)/Al2O3 nanocomposites via in situ polymerization were studied. The nanoparticle loading was varied from 0.3 to 1 wt.%. From the DSC results, no significant differences were recorded for melting temperatures. However, simple added PET/Al2O3 nanocomposites slightly changed to the lower melting temperature. Morphology of the nanocomposites has been examined by SEM. From the SEM results revealed that dispersed Al2O3 nanoparticles in the EG (ethylene glycol) during the polymerization can be well dispersed in PET matrix.
