Development of polymeric conducting materials is an important step when planning applications in bioelectrochemistry. In this work, biocompatible gelatin-based hydrogels prepared with ionic liquids are characterized in terms of their swelling behavior in aqueous solutions. These polymers swell much less than hydrogels made solely with gelatin and they dissolve at temperatures above 25 °C. Hydrogel age can be an important factor that determines the maximum swelling, since one type of polymer swells substantially less as more time elapses after its preparation.
