Hydrogels are three-dimensional polymeric networks that can absorb and retain large quantities of water in relation to their physical size. By incorporating stimuli-responsive units into the gel structure, hydrogels can be actuated by external stimuli such as photo, thermal, electro and pH, among others. Herein, we demonstrate that the size and volume of a pH sensitive hydrogel based on acrylic acid (AA) and acrylamide (Am) can change when exposed to di erent pH environments. The pH responsive hydrogels that were developed used copolymers of AA and Am in di erent molar ratios 30:70, 50:50 and 70:30, respectively.
