Abstract
A material that includes an organic polymer capable of being rendered electrically conductive by electrochemical oxidation or reduction, and a redox compound ionically or covalently bonded to the polymer. The redox potential of the redox compound is more positive than the redox potential of the polymer when the polymer is electrically conductive in the oxidized state and more negative than the redox potential of the polymer when the polymer is electrically conductive in the reduced state.
