Active polymer gels are soft materials with adaptive action. Their function is based on non-covalent binding in the gel network, either in a sense of transient chain connectivity or in a sense of delicate interactions of the chains with their environment. Both modes of action can serve in various advanced applications in which a gel specimen serves to adapt its viscoelasticity and/or permeability in response to external parameters. However, to make this all truly useful, it is necessary to understand the mutual interplay between (nano)structure, dynamics, and properties of these fascinating materials. This is what our research is focusing upon.
