摘要

We investigated the impact of hydrophobic (MLIPO) and hydrophilic (MHYDRO) monomer additives on surface properties of UV-cured hybrid organic-inorganic thin coatings. Transparent coatings were obtained by UV-curing mixtures of a commercial silica diacrylate (Dp= 50 nm , SiO_2= 50%) mixed with different amounts of the above monomers. Surface energy measurements showed that hydrophobic or hydrophilic surface properties are both controlled by the amount of additives and by SiO_2 loadings. We also found by a staining and cleaning procedure that the hybrid hydrophilic coatings resist very well to dirt pick-up and to oil staining while the hydrophobic coatings exhibit excellent water-repellency and easy-to-clean properties. The colloidal silica also contributed significantly to resistance to abrasion without affecting gloss and transparency.
