  Article:   UV VIS BEHAVIOR OF DOPED PVA TiO2 MEMBRANES UNDER GAMMA IRRADIATION.

Authors:  L. UDRESCU, E. DINTE, C.V. POP, M. TODICA.
 
       
         
  Abstract:  The UV-VIS absorption properties of PVA-TiO2 composite materials γ irradiated were investigated in function of concentration of TiO2 and the dose of radiation. The UV absorbance of unirradiated samples increases with the concentration of TiO2. Important modifications of this property appear after γ irradiation.

Keywords: PVA, TiO2, gamma irradiation
