20.500.12556/RUL-132855 Field test of self-cleaning Zr-modified-TiO$_2$-SiO$_2$ films on glass with a demonstration of their anti-fogging effect 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. self-cleaning anti-fogging titanium dioxide silica field test glazing TiO$_2$-SiO$_2$ samočistilne površine protizarositvene površine titanov dioksid silicijev dioksid terenska raziskava zasteklitev true false true Angleški jezik Slovenski jezik Članek v reviji 2021-11-05 10:45:23 2021-11-05 10:45:24 2022-09-12 04:14:03 0000-00-00 00:00:00 2019 0 0 14 str. iss. 13, art. 2196 Vol. 12 Jul. 2019 0000-00-00 Zaloznikova Objavljeno NiDoloceno 0000-00-00 0000-00-00 0000-00-00 620.1:546.82-31:546.28-31 1996-1944 10.3390/ma12132196 1538290883 RAZ_Suligoj_Andraz_2019.pdf RAZ_Suligoj_Andraz_2019.pdf 1 DE4726982F37548B40E1C8174CE13294 4d99f4a7044592f1e523c66f1f85f680285fd8b72e57ac6985ec12ebd50909b3 d875e114-3e1d-11ec-abdb-00155dcfd717 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=150590 https://www.mdpi.com/1996-1944/12/13/2196 1 0e228b3b-3e1d-11ec-abdb-00155dcfd717 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=150589 Fakulteta za kemijo in kemijsko tehnologijo Fakulteta za gradbeništvo in geodezijo 0 0 0
