The addition of TiO2 made film less transparency than ZnO because TiO2 particles were physically smaller than
ZnO particles. In addition, we found that TiO2 increased thermal stability of PET/PBS blends. The addition of TiO2
and ZnO would not significantly increase tensile strength, young’s modulus and percentage elongation at break. The
result of antibacterial testing of PET/PBS blends thin film with TiO2 exhibited better performance of inhibiting
E.coli and S.aureus bacteria than the one with ZnO.
