The Effect of Zno Nanoparticles on the Color Change of Polyester

In this study, the effect of adding zinc oxide nanoparticles (ZnO) on the general color change and transparent adhesion strength of polyester folds was studied in wood (Ulmusglabra). Zinc oxide nanoparticles with concentrations of 0, 0.22, 0.20,1, 1.20 and 2% of coating weight were combined. In a study about adherence resistance of coating the results showed that the highest adhesion in Nano coatings contained 1% nanoparticles of zinc oxide, and adding more than this had a negative effect on the adhesion of coating. In the case of general color change, the addition of zinc oxide nanoparticles is also caused a change in the color of samples coated with nanoparticles. However, in small amounts of nanoparticles, color changes were made and the brightness reduction was not significant.
