Abstract
The structure and properties of three types of cured PhN/metal oxide nanocomposites with Al2O3, TiO2, or ZnO nanoparticles of an average diameter of 60 nm, which were treated with aminopropyltrimethoxysilane GX-540 as coupling agent, are described. In all cases, a satisfactory dispersion of nanoparticles was achieved. A significant improvement in the thermomechanical properties of nanocomposites with respect to the properties of the neat matrix was shown. The experimental data obtained for the elastic modulus of the studied Al2O3-containing nanocomposites were compared with the Series, Halpin–Tsai, and Kerner theoretical models; the best match was shown for the Halpin–Tsai model. The barrier properties of the TiO2-containing nanocomposites as anticorrosive protective coatings were shown. The UV–visible transmittance spectra of the ZnO-containing nanocomposites showed that adding ZnO nanoparticles improved the UV-shielding properties of the neat matrix.
