ABSTRACT:
Disclosed is a heterogeneous polymer gel comprising at least two gel networks. One embodiment of the present invention concerns a heterogeneous polymer gel comprising a first gel network comprising an environmentally-stable gel and a second gel network comprising an environmentally-unstable gel wherein the first gel network interpenetrates the second gel network. The heterogeneous polymer gel exhibits controlled changes in volume in response to environmental changes in condition, such as of temperature or of chemical composition.
