Ionically-driven Coacervate Hydrogels

Coacervate Hydrogels
People Involved with this Research Area: 

Combining the power of oxyanionic polymerization and thiol-ene click chemistry, we can form hydrogels from a binary mixture of solutions containing fully watersoluble and oppositely-charged triblock copolymer precursors. The key to the physical associations in these materials derives from the charged end-blocks, which when combined in solution will phase-separate to form coacervate-domain crosslinks. These unique hydrogel materials are remoldable, injectable, require no cosolvents to form, and are responsive to pH and salt concentration.
