Abstract
A method of enhancing the conductivity of various conductive polymer products, such as a conductive polymer product obtained by polymerizing 3,4-ethylenedioxythiophene in an aqueous solution of polystyrenesulfonic acid. The method of enhancing the conductivity of a conductive polymer product includes placing a conductive polymer product, water, an organic solvent compatible with the conductive polymer product, and carbon dioxide gas in a pressure vessel; and applying heat and pressure to an interior of the pressure vessel to bring the carbon dioxide into a supercritical state.
