Özet

In this study, epoxy and methacrylate-based silane coupling agents are used together with titanium oxide to form a hybrid coating system on the glass surface. In the experimental study, an organic–inorganic molecular hybrid compound was prepared by sol-gel method. First glasses were cleaned by traditional piranha solution (3:1 H2SO4: H2O2) to remove contaminants. In order to improve the adhesion of hybrid coatings on glass substrates silanization treatment was applied. Silanization solution was prepared by dissolving 1 g 3-aminopropylTriethoxysilane (3-APTES) in 100 mL 2-propanol. Glass substrates were coated with this solution using a dip-coater. Silanes (3- Glycidoxypropyltrimethoxysilane, GLYMO and 3-(trimethoxysilyl) propylmethacrylate, TMSPM or MEMO) were mixed deionized water and 2- propanol. Titanium oxide was added and mixed the silane solutions for 1 hour. The resultant solution was coated on a glass sheet by dip coater with heater. After evaporation of solvents, coated samples were characterized by Fourier Transform Infrared Spectrophotometer (FTIR), Scanning Electron Microscope with Energy Dispersive X-ray Spectroscopy (SEM-EDX) and Contact Angle Goniometer.
