Tóm tắt tiếng anh
This work aims to explore how ZnO nanoparticles enhance the mechanical, photoaging, and self-cleaning properties of water-borne acrylic coating. Micro/nano-ZnO particles (at 2 wt.% of total solid resin) were dispersed into the acrylic polymer matrices using ultrasonication to under-stand the effect of the size of the coating properties. The effect of ZnO particles on the properties of composite coatings (25 �m of thick) have been evaluated through various tests, such as abrasion measurement, ultraviolet/condensation (UV/CON) weathering aging, and methylene blue self-cleaning. Experimental data indicated that the incorporation of ZnO particles enhanced both abrasion resistance and methylene blue removal efficiency of the water-borne acrylic coatings, with nano-ZnO particles being the best. However, the weathering degradation of nanocomposite coatings was more severe as compared to the coating with micro-ZnO (at the same ZnO content). � 2021 by the authors.
