Redox initiation reaction of polyether urethane diacrylamide (PEUDAm) macromer + N-acryloyl glycinamide (NAGA) delivered using double barrel syringe with a mixing head. Ammonium persulfate (APS) and iron gluconate (IG) are used as initiator and reducing agents. Resulting hydrogels display bidentate hydrogen bonding at netpoints for improved durability. Ionic conductivity is conferred through the inclusion of salt species in the hydrogel precursor solution.
