چکیده انگلیسی
ⶠThis work explains an efficient approach to improve weathering performance of an polyurethane based coating with employing silane coupling agent treated TiO2 nanoparticles. ⶠWeathering performance of PU nanocomposites coatings was investigated utilizing colour coordinates data collection, tensile strength measurements and surface morphology evaluation. ⶠTEM and AFM observations revealed that the APS treated nanoparticles have a better dispersion and smaller agglomeration, compared with their untreated counterparts. ⶠThe results revealed that addition of 0.5-1.0 wt.% APS treated TiO2 nanoparticles reduces photocatalytic activity, and improves the weathering performance PU nanocomposite coatings. ⶠResults also revealed that the colour measurement is a useful technique and non destructive method for evaluation of coating's performance against weathering conditions.
