Determination of the microstructure, the swelling degree and dynamics of cryogels based on methacrylic acid, dimethylaminoethylmethacrylate and acrylamide

Abstract

By the method of radical polymerization, cryogels were synthesized on the basis of methacrylic acid, crylamide and dimethylaminoethylmethacrylate in proportions of cryogels (%) 20:20:60, 20:60:20, 60:20:20, 40:40:20, 15:45:40, 45:15:40. The microstructure of cryogel was studied by the method of electrone microscopy. It was revealed that cryogels have super macroporous. The degree and dynamics of cryogel swelling in water solutions was identified, fluid diffusion mechanism in the scope of cryogel was identified as well. It was determined that the diffusion of liquids in cryogels obeys Fick ׳s law.
