COBISS.SI-ID: 1537937347The possibilities for savings in the building sector lie in the application of fenestration with advanced properties. Dynamic control of incoming/ outcoming solar energy through windows can be obtained by using thermochromic materials. One of them is vanadium(IV) oxide (VO2) that show characteristic metal-to-insulator transition at about 68 °C. In this study we present thermochromic coatings prepared from commercial VO2 (Alfa Aesar), hydrothermally prepared VO2 doped with antimony tin oxide (VO2/ATO) and VO2 coatings prepared by synthesis from vanadyl sulfat. The prepared types of powders were further introduced into dispersions through milling with zirconia beads. The optical performance of coatings was determined in a custom-made holder that enabled heating of coatings from room temperature to above 100 °C. Differential scanning calorimetry (DSC) was used for determination of metal-to-insulator transition. Morphology and structure of prepared powders was characterised using SEM microscopy, X-ray powder diffraction (XRD) technique and Raman spectroscopy. VO2 coatings were deposited on float glass by spin-coating technique.

COBISS.SI-ID: 6449434This presentation dealt with the low-temperature V-oxide films that can be deposited on polymeric substrates. The films were made from dispersions of V2O5 nanoparticles. The dispersions were prepared by milling of commercial V2O5 powder in isopropanol. As a dispersant vanadium(V) tri-n-propoxide oxide was added. The films were deposited using spin-coating technique and heated at 150 °C. The optical performance of films during coloration and bleaching was followed using in situ UV-visible spectroelectrochemistry. Low-temperature V-oxide films were also used for assembly of electrochromic device with optically active and substoichiometric nickel(II) oxide film. Ormolyte was used as an electrolyte.
