  Abstract:  The effect of UV exposure on PVA membranes doped with TiO2 was observed by UV-vis and Raman spectroscopy. After several hours of moderate UV exposure, the absorption coefficient of non doped membranes is modified. The absorption property of PVA was enhanced by addition of TiO2.

Keywords: PVA, UV-vis Raman spectroscopy, TiO2
