    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 ration 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 of pure water. The process produces low ESR and low leakage valve metal capacitors with conductive polymer cathodes.

    摘要： A process for forming a solid electrolytic capacitor and an electrolytic capacitor formed by the process. The process includes: providing an anode wherein the anode comprises a porous body and an anode wire extending from the porous body; applying a thin polymer layer onto the dielectric, and forming a dielectric on the porous body to form an anodized anode; applying a first slurry to the anodized anode to form a blocking layer wherein the first slurry comprises a first conducting polymer with an median particle size of at least 0.05 µm forming a layer of crosslinker on the blocking layer; and applying a layer of a second conducting polymer on the layer of crosslinker.
