 This research paper examined the effects of steam sterilization on three types of hydrogels made from different stimuli responsive polymers. The carbapole 940 hydrogel was found to be the most resistant to the effects of steam sterilization while the Pluronic F127 and sodium alginate hydrogels were more susceptible to changes in their properties. Steam sterilization did not significantly affect the chemical and physical characteristics of any of the hydrogels tested.
