circulatory system. Thus, they have the potential of creating a new class of structural
nanocomposites of ionic polymers and conductors such as metals or carbon nanotubes.
These contain an embedded circulatory system capable of producing electrically
controlled localized internal pressure changes to hydraulically pump liquids contain-
ing ions and chemicals to various parts of the material to cause sensing, actuation,
and large changes in stiffness and conductivity and to perform self-repair or healing.
Ionic polymers equipped with a distributed network of electrodes created by a
chemical plating procedure, such as IPMNCs, are capable of creating an intrinsic
distributed circulatory system of ions, chemicals, water, and polar and ionic liquids
