Abstract :
Surface photomodification of polyethylene (PE) films by using new azidobenzenesulfonamides was carried out. The wetting angles for three liquids of different polarity (water, formamide and diiodomethane) have been studied to estimate the surface modification performed. The received values of wetting angles for determining the surface free energy ¿S (¿) by the Owens-Wendt and Lifshitz-van der Waals ¿LW, acid-base ¿AB by the Lifshitz-van der Waals/acid-base methods.
