Abstract
The radiation-induced changes in Poly (vinyl alcohol) (PVA) polymer films exposed to electron irradiation were investigated for different radiation dose. Polymer film samples were irradiated in air at room temperature by an electron beam accelerator at different doses: 0, 100, 150 and 200 kGy. The microstructural and surface properties of the irradiated PVA films were characterized by X-ray diffraction (XRD) and Atomic force microscopy (AFM). An unirradiated PVA film was used as reference. Electron irradiation was found to induce changes in structural and surface properties of polymer films and such changes vary depending on the radiation dose.
