Preliminary spectroscopic investigation of some PVA membranes gamma irradiated

Abstract

The UV-VIS absorption property and the structural modification of PVA membranes gamma irradiated were investigated by XRD, UV-VIS and Raman spectroscopies. The increase of UV absorbance is observed after irradiation. This behavior is correlated with the scission effect and local ordering of the polymeric chain induced by irradiation. These effects were probed by XRD and Raman spectroscopy. © 2012 Versita Warsaw and Springer-Verlag Wien.
