Abstract<\/span><\/span><\/span><\/span><\/p>\n

This work aims to clarify the photocatalytic degradation mechanism and heat reflectance recovery performance of waterborne acrylic polymer\/ZnO nanocomposite coating. To fabricate the nanocomposite coating, ZnO nanoparticles (nano\u2010ZnO) were dispersed into acrylic polymer matrix at the various concentrations from 1 to 6% (by total weight of resin solids). The photocatalytic degradation of nanocomposite coating under ultraviolet (UV) light irradiation has been investigated by monitoring its weight loss and chemical\/microstructural\/morphological changes. As the topcoat layer, its heat reflectance recovery has been evaluated under UV\/condensation exposure by using an artificial dirty mixture of 85 wt% nanoclay, 10 wt% silica particles (1\u20135 \u03bcm), 1 wt% carbon black, and 2 wt% engine oil. After 108\u2010cycle UV\/condensation exposure, infrared spectra and weight loss analysis indicated that the maximal degradation for nanocomposite coating is observed at 1 wt% nano\u2010ZnO. On the other hand, after 96 hr of UV light exposure, the nanocomposite coating with1 wt% nano\u2010ZnO could restore effectively the reflective index of solar\u2010heat reflectance coating (from 58.45 to 80.78%). Finally, the photodegradation mechanism of this waterborne acrylic polymer coating has been proposed as the UV\u2010induced formation of C\uf8feC\uf8ffC\uf8feO conjugated double bonds. As a result, its self\u2010cleaning phenomenon can be achieved as the recovery of heat reflectance.<\/span><\/span><\/span>\u00a0<\/span><\/span><\/p>\n<\/p><\/div>\n","protected":false},"excerpt":{"rendered":"
