Swelling Behavior Study of γ-Irradiated Gelatin Hydrogels Prepared in Organic/Aqueous Mixtures
E-mail:
In these studies, the swelling behaviors of γ-irradiated gelatin hydrogels in the presence of a water miscible organic solvent were reported. The addition of DMSO or dioxane to the reaction medium during a γ-irradiation process provided gelatin hydrogels with a considerably high swelling property. On the other hand the addition of acetone or acetonitrile under same γ-irradiation condition provided gelatin hydrogels with low swelling property. This observation indicates that the swelling of the hydrogels could be controlled by organic additives and their contents added into the gelatin solution prior to a γ-irradiation.
