Abstract

In this study, the effect of adding ZINC OXIDE NANOPARTICLES (ZnO) on COLOR CHANGE and adhesion strength of POLYURETHANE CLEAR COAT in elm (Ulmus glabra) wood was investigated. ZnO nanoparticles at the dosage of 0, 0.25, 0.50, 1, 1.50 and 2 wt% were dispersed in coating. TEM (Transmission electron microscopy) images were used to investigate the dispersion of nanoparticles in coatings matrix. Results of investigation showed the dispersion of nanoparticles in polyurethane coating indicating that the best dispersion of nanoparticles was obtained in coating containing 1 wt% nano. Increasing the dosage of nanoparticles to 2 wt%, reduced dispersion of nanoparticles and aggregates of nanoparticles were observed in coating. Investigating the ADHESION STRENGTH OF COATING showed that the highest value of adhesion was in nanocomposite coating with 1 wt% nano but higher ratios of nanoparticles had negative effect on coating adhesion. Results also revealed that adding ZnO nanoparticles, changed color of samples coated with nanocomposite coating but it was not significant in low content of nanoparticles.
