Thermal behavior of polyacetylacetonatozirconium (PAZ)

The thermal behavior of polyacetylacetonatozirconium (PAZ) was characterized by thermogravimetry–differential thermal analysis–derivative thermalgravimetric (TG–DTA–DTG) techniques. The thermal decomposition studies under air, N2 flux and N2 flux after pretreated by steam showed different thermal behavior modes. Further investigation revealed that the steam pretreatment had extraordinarily significant effects on the thermal behaviors of PAZ. X-ray powder diffraction (XRPD) and Fourier transform infrared spectroscopy (FT-IR) were used to indicate the morphology form and confirm the composition of PAZ during the heat-treatment.
