چکیده انگلیسی
Composite membranes based on gellan and poly(N-vinylimidazole) were prepared by using the method of solvent evaporation. In acid medium ionic interactions are established and evidenced by measurements of FTIR spectroscopy. The properties of these membranes were investigated by using elemental analysis, thermogravimetric analysis, atomic force microscopy and dynamic swelling experiments. The thermic behavior of the membranes depends on the nature of interactions and swelling degree is highly dependent on pH and composition. The properties of these membranes suggest potential applications in the field of biodegradable materials or as supports for drugs in view of their controlled release.
