| Abstract Scope |
The technology of superhydrophobic ceramic coatings with self-cleaning properties gained strong attention during recent years. Impurities on treated materials are easier removed which leads to reduced maintenance costs and offers a green alternative to aggressive cleaning agents. The potential of commercial products is immense, but the wide range of possible applications is limited by the low temperature and mechanical stability. A route for the preparation of a superhydrophobic coating with mechanical and thermal stability was fabricated on glass substrates. The coating was formed in a solution containing various nanoparticles such as SiO2, TiO2 and ZrO2 and silicic acid, in which the ratio of silicic acid was varied. For receiving superhydrophobicity, subsequent and in-situ functionalization with low surface energy material has been performed. Robust thermally stable films with contact angle close to 180° were preserved even after temperature treatments up to 350 °C and mechanical tests. |
