Abstract

We report the effect of UV annealing on post-γ-ray-irradiated spin-coated γ-APTES and γ-APTES + NPs + UV. The structure changes of the membranes were characterized using Fourier transform infrared spectroscopy (FTIR) and atomic force microscopy (AFM). We found that the absorption peaks of the Si-O-Si-related bonds of the FTIR spectrum varied with time after 10 kGy γ-ray irradiation. The absorption peak of the NH3 + bonds of the post-irradiated membranes showed less sensitive to hydrogen ions. The AFM surface morphologies showed great grain reconstructions after γ-ray irradiation for all the membranes. However, following the UV annealing process, both the FTIR spectrum and AFM surface morphologies showed that only the spin-coated γ-APTES + NPs + UV membrane could be restored to the pre-irradiated status. It is believed that the nanocomposite of silica NPs mixed with γ-APTES forms a lot of γ-APTES/SiO2 interfaces which enhance the post-irradiation UV oxidation and hence restore the membrane from degradation.
