    摘要： An intrinsically conductive polymer is prepared with a chemical oxidative process. The polymer is prepared by first dipping or coating a substrate with an Fe(III)-containing oxidizer solution and drying. The substrate is then dipped or coated with a monomer, such as 3,4-ethylenedioxythiophene solution, and reacted to form the conductive polymer. The monomer is dissolved in a solvent in which it has a high solubility but in which the Fe(III)-containing oxidizer has low solubility. This minimizes cross-contamination of the monomer and oxidizer dipping solutions thereby making this process suitable for high volume production. Dissolving the monomer in a solvent allows control over the stoichiometric ratio of monomer to oxidizer and prevents an excess of monomer thereby facilitating the removal of any unreacted monomer by water. The substrate is then dipped in an aqueous solution of para-toluenesulfonic acid to facilitate the removal of Fe(II) byproducts by enhancing their solubility in water and then the substrate may be washed with an aqueous solution or pure water. The process produces low ESR and low leakage valve metal capacitors with conductive polymer cathodes.

    摘要： An electrolytic capacitor comprising a thermally treated anode prepared by heating a manganese dioxide coated porous anodized valve metal nitride anode to a temperature of about 325° C. to about 450° C. The anode may be heated to first temperature of about 200° C. to about 250° C. for a time sufficient for the valve metal nitride anode to reach thermal equilibrium, prior to increasing the temperature to about 325° C. to about 450° C.
