Resumen
Polyacrylamide/chitosan hydrogels were synthesized in aqueous itaconic acid solution (1% w/w), in order to determine its swelling kinetics at various chitosan concentrations. Analysis of the hydrogel swelling behavior indicated that the network properties of the gel changed depending on the swelling pH, as well as the amount of chitosan, showing a decrease in swelling capacity when the chitosan concentration was increased; this behavior can be explained due to the presence of the chitosan ionic groups.
