The thermal and crystallization properties of poly(ethylene terephthalate) (PET) in the presence of metaleorganic frameworks (MOFs) such as UiO-66(Zr) were systematically studied. UiO-66(Zr) functions as a key nucleating agent in the PET scheme, and adding UiO-66 accelerates the crystallization of PET.
The thermal and crystallization properties of poly (ethylene terephthalate) (PET) in the presence of metaleorganic frameworks (MOFs) such as UiO-66(Zr) have been systematically studied. Under the best conditions, UiO-66(Zr) functions as a key nucleating agent in the PET scheme. In this work, a merge between UiO-66 and PET was used to increase compatibility, however, the tetra oxidation of Zr4+ revealed by defects in UiO-66 was used to enhance the reaction between PET and UiO-66 as well. Additionally, PET containing varying amounts of UiO-66 were made-up. UiO-66 has high nucleation effectiveness in the matrix of PET due to its large specific surface area and coordination of Zr4+. When compared between the formation PET and PET/UiO-66 matrix, the rate of crystallization for PET/UiO-66 nanocomposite was considerably accelerated, and the temperature of crystallization for PET-UiO-66 was remarkably increased or decreased with increasing UiO-66 content, indicating that adding UiO-66 to PET accelerates crystallization. The thermal stability of PET/UiO-66 nanocomposites in terms of characteristic temperature and kinetic parameters, as well as the dispersion of UiO-66, were examined using both (DSC) and (TGA) under non-isothermal circumstances. The degrading response rate (dx/dt)p and the kinetic exponent n of PET/UiO-66 nanocomposites are estimated and analyzed. (C) 2022 The Author(s). Published by Elsevier B.V.
