Özet
New hybrid inorganic-organic glass coating materials, which contain polyethyleneglycol/ gamma-glycidoxypropyltrimethoxysilane/ titanium(IV)-n-propoxide(2-methoxyethylacetoacetate)/ chromium(III) nitrate [PEG/GPTMS/Ti(OR)(2-MEAA)/Cr3+] have been developed for UV-light absorption by using the sol-gel process. The effect of agitation time and temperature on UV-light absorption was investigated. The titanium complex was characterized by H-1-NMR and FTIR spectroscopies. UV-Vis spectroscopy was used to investigate the optical properties of the coating materials. The results show that the coated glass has very low transmission in the UV region (300-400 nm) compared to the uncoated glass, especially at 150, 200, 250 and 300 degrees C treatment temperatures after 1- and 18-hour agitation times. The UV-light transmission of the coated glass was not different from the uncoated glass between 80-100 degrees C and 350-500 degrees C.
