Soft and Wet Materials: Polymer Gels



A polymer gel is a soft and wet material capable of undergoing large deformation. A deformed gel, in turn, changes its chemical potential, behaving as an energy transducer. Thus, a polymer gel shows a variety of stimuli-responsive actions, responding to external environmental changes. In this article unique electrical, thermal, and chemical responses of polymer gels are described. Recently observed frictional specificities of gels are also briefly introduced.
