Abstract :In this study, epoxy and methacrylate based silane coupling agents are used together with titanium oxide to form a hybrid coating system on 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 insert ignore into journalissuearticles values(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-aminopropyl-Triethoxysilane insert ignore into journalissuearticles values(3-APTES); in 100 mL 2-propanol. Glass substrates were coated with this solution using a dip-coater. Silanes insert ignore into journalissuearticles values(3-Glycidoxypropyltrimethoxysilane, GLYMO and 3-insert ignore into journalissuearticles values(trimethoxysilyl);propylmethacrylate, TMSPM or MEMO); were mixed deionized water and 2-propanol. Titanium oxide was added and mixed the silane solutions for 1 hour. After modified solution was coated on a glass sheet by dip coater with heater. After evaporation of solvents, coated samples were characterized by Fouirer Transform Infrared Spektrofotometre insert ignore into journalissuearticles values(FTIR);, Scanning Electron Microscope with Energy Dispersive X-ray Spectroscopy insert ignore into journalissuearticles values(SEM-EDX); and Contact Angle Goniometer.
