Functional UV Blocking and Superhydrophobic Coatings Based on Functionalized CeO and AlO Nanoparticles in a Polyurethane Nanocomposite.

Water repellency has significant potential in applications like self-cleaning coatings, anti-staining textiles, and electronics. This study introduces a novel nanocomposite system incorporating functionalized AlO and CeO nanoparticles within a polyurethane matrix to achieve hydrophobic and UV-blocking properties. The nanoparticles were functionalized using an octadecyl phosphonic acid solution and characterized by FTIR and XPS, confirming non-covalent functionalization.
