Field test of self-cleaning Zr-modified-TiO$_2$-SiO$_2$ films on glass with a demonstration of their anti-fogging effectŠuligoj, Andraž (Avtor) Pliekhova, Olena (Avtor) Vodišek, Nives (Avtor) Mihelčič, Mohor (Avtor) Surca, Angelja Kjara (Avtor) Kunič, Roman (Avtor) Šubic, Barbara (Avtor) Starman, Jernej (Avtor) Ugovšek, Aleš (Avtor) Lavrenčič Štangar, Urška (Avtor) self-cleaninganti-foggingtitanium dioxidesilicafield testglazingTiO$_2$-SiO$_2$The number of commercial products claiming self-cleaning properties is rising and testing of long-term activity and durability of such coatings needs to be addressed more. The time-dependent changes of different characteristics like haze, transparency, and color are essential for transparent glazing materials. Herein, we aimed to examine whether the laboratory results obtained on the Zr-modified-titania-silica (TiZr) self-cleaning materials would translate to larger-scale outdoor-exposed testing. TiZr thin films were deposited via spraying onto float glass window surfaces and exposed into three different environments for 20 months. For comparison, a commercially available active SGG BIOCLEAN$^{TM}$ glass and standard float glass were simultaneously exposed in the same conditions. It was shown that the self-cleaning property of either a commercial product or TiZr-coated float glass was not considerably effective in real field test conditions, although the previous laboratory tests showed pronounced photocatalytic activity of TiZr thin films. The inclination angle; however, was shown to have a considerable effect on the self-cleaning ability of samples, as did the rain patterns during the testing period. On the other hand, the anti-fogging effect of our TiZr material was very well expressed in controlled laboratory conditions (measuring droplet formation time) as well as in the real outdoor environment.20192021-11-05 10:45:23Članek v reviji132855UDK: 620.1:546.82-31:546.28-31ISSN pri članku: 1996-1944DOI: 10.3390/ma12132196COBISS_ID: 1538290883sl
