Synthesis and Characterization of Poly (Acrylamide - co - Acrylic acid) Hydrogel Containing Silver Nanoparticles for Antimicrobial Applications
نویسندگان
چکیده
Acrylamide was copolymerized with acrylic acid at different ratios using potassium persulphate initiation system in presence of a crosslinking agent and different doses of silver nitrate to yield hydrogels containing silver nanoparticles upon post treatment with sodium hydroxide. Swelling capacity and kinetics of swelling of these hydrogels were studied. Size and distribution of the nanoparticles and their dependence on acrylamide / acrylic acid ratios as well as on the dose of silver nitrate were also studied using Transmission Electron Microscopy (TEM). Furthermore, the antimicrobial and antifungal activities of the hydrogels in correlation with TEM results were reported. Hydrogels samples having relatively large number of Ag nanoparticles and widely distributed smaller particle size inhibit bacterial and fungal growth. [Fatma S. Aggor; Enas M. Ahmed, A.T.
