Resumen:
Pure ZrO2 nanocrystals were successfully prepared from three new complexes of hydrous zirconium acetylacetonate ([Zr2(AcAc)•4H2O]2, [Zr2(AcAc)-PEI•nH2O]2 and [Zr2(AcAc)-PDDAC•nH2O]2), obtained using solvothermal synthesis. The addition of poly(ethyleneimine) (PEI) and poly(diallyldimethylammonium chloride) (PDDAC) hydrophilic polymers as stabilizing agents, had impact on the size and crystalline phase of the calcinated products within a range of 300 to 800 °C, obtaining ZrO2 nanoparticles with tetragonal and/or monoclinic structure and diameters of 5 to 20 nm. The synthesized precursor complexes and ZrO2 were characterized by thermogravimetry (TGA), differential scanning calorimetry (DSC), X-ray diffraction (XRD), UV-Vis spectroscopy, Fourier transformed infrared spectroscopy (FT-IR/FIR) and Raman spectroscopy. © 2020, S.C.
