Figure 2.

Photographic images, SEM images and XRF analysis data of coatings on wooden substrates: (a) photographic top view images of 25 × 25 mm samples reveal a more yellow coloring of nano-ZnO/Ag-based coatings compared to nano-ZnO-based and pure matrix coatings; (b) top view and (c) cross-section SEM images reveal a similar distribution for both nano-ZnO- and nano-ZnO/Ag-embedded nanoparticles; (d) Zn content (µg/cm²) was determined using X-ray fluorescence spectroscopy. Zn content in both nanoparticle-based coatings was similar and notably higher compared to the control (pure matrix-covered substrate).
