Abstract

New azidobenzenesulfonamides were synthesized and their photochemical properties were investigated. Surface modification 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 γS (γ), as well as its components – polar γs p , dispersive γs d by the Owens-Wendt and Lifshitz-van der Waals γLW, acid-base γAB by the Lifshitzvan der Waals/acid-base methods. Antimicrobial activity of PE films with sulfonamide moiety was screened in vitro in the following bacterial cultures: Staphylococcus aureus, Escherichia coli, Mycobacterium luteum, Cystopteries tenuis. Preliminary screening of PE films with sulfonamide moiety revealed their inhibitory action against some kinds of bacteria..
