Ultraviolet/visible and Fourier transform infrared spectroscopic investigations of organic-inorganic hybrid layers for UV protection

► Vacuum deposited organic-inorganic UV protective coatings for polycarbonate ► Thermal co-evaporation of organic UV absorbing compounds with silica ► Matrix materials and the absorber concentration influence the absorption behavior. ► The coatings on PC show improved UV stability under artificial irradiation. ► The hydroxyphenyltriazine-silica layer shows best UV protection results.
