This could lead to a better dispersion and more effectiveness as the nucleating site.
However, both of % crystallinity of PET and PBS significantly dropped when the addition of 2% wt of either TiO2
or ZnO was taken place in PET/PBS blends. Because the higher amount (at 2%wt) of TiO2 and ZnO tended to be
easily aggregate. Particularly for TiO2, the percentage of PET and PBS crystallinity drastically decreased at higher
content of 2%.
