The effect of adding zinc oxide nanoparticles on color change and adhesion strength of polyurethane coating on wood surface

In this study the effect of adding zinc oxide nanoparticles (ZnO) on color change and adhesion strength of polyurethane clear coat in Elm wood species (Ulmus glabra) investigated. ZnO nanoparticles with concentration of 0, 0.25, 0.50, 1, 1.50 and 2 wt% were dispersed in coating. TEM (Transmission el...
