Abstract

Polysulfone (Pfu) films were modified by grafting poly(vinyl alcohol) (PVA) by the oxidative pre-irradiation technique. To achieve this modification, some parameters were modified such as the radiation dose, the concentration of PVA, the temperature and the reaction time. It was found that the grafted films with 12% presented a greater grafting percentage (0.86%). The modified films were characterized by means of the contact angle, Fourier transform infrared spectroscopy (FTIR-ATR) and scanning electron microscopy (SEM) techniques.
