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,

PROBLEM TO BE SOLVED: To simplify the production process of a conductive polymer thin film and a conductive polymer solution.SOLUTION: The conductive polymer solution contains a doped conjugated polymer and an organic solvent. The doped conjugated polymer has a conductivity and a polymer thereof is selected from polyacetylene, polypyrrole, polyparaphenylene, polythiophene, polyfuran, poly(3,4-ethylenedioxythiophene), poly(3,4-propylenedioxythiophene), polythianaphthene, polyaniline, derivatives thereof, and combinations thereof. The organic solvent is a fluorine-containing organic solvent, a mixed solvent with a fluorine-containing organic solvent, or a mixed solvent of a fluorine-containing organic solvent with an organic solvent containing no fluorine. The organic solvent is mixed with the doped conjugated polymer. A method for producing a conductive polymer is also provided.

PROBLEM TO BE SOLVED: To provide an optically driven actuator having flexibility, being lightweight, and having an optical responsivity wherein it deforms reversibly at a high speed in response to a light stimulation, as well as driven soundlessly; and a simple manufacturing method for the optically driven actuator. SOLUTION: The optically driven actuator comprises a crosslinked polymer obtained by crosslinking at least a part of side chains of a condensation polymer having, in the main chain, a photoisomerizing group which induces structural change while undergoing optical stimulation, the crosslinked polymer being deformed reversibly in response to a light stimulation, to thereby serve as an actuator.

Abstract:
PROBLEM TO BE SOLVED: To provide a conductive material having high conductivity than a π-conjugated polymer by simply controlling and improving the conductivity of the π-conjugated polymer. SOLUTION: The conductive material is obtained by bringing a π-conjugated polymer into contact with an ionic liquid. The conductive material preferably has a conductivity ten times or more higher than that of the π-conjugated polymer before it is brought into contact with the ionic liquid.
