Abstract:
This invention provides a triggered response composition in the form of a barrier material and a delivery device that includes one or more polyelectrolytes in contact with an aqueous system that is stable and insoluble in an aqueous system and that exhibits one or more chemical/physical responses in the aqueous system, wherein the chemical/physical response of the composition is triggered upon one or more changes in ionic strength of the aqueous system.
