| Abstract: | Transparent ZrO_2-polyurethane nanocomposites with high refractive index were prepared by dispersing ZrO_2 nanoparticles in a polyurethane matrix via ligand molecule engineering.TEM showed that the inorganic particles were well dispersed within the polymeric network with no significant macroscopic agglomeration.By controlling the phase separation it was possible to obtain transparent zirconia nanostructured coatings,characterized by improved mechanical and thermal properties.UV-Vis spectra indicated that th... |
