    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; apply a thin polymer layer onto the dielectric, andforming 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; andapplying a layer of a second conducting polymer on the layer of crosslinker.

    摘要： The adhesion of a conductive polymer film to an oxidized porous pellet anode is improved by the incorporation of a silane coupling agent in the polymer impregnating solution. The incorporation of the silane coupling agent also decreases leakage current and dissipation factor. Suitable silanes are those of the general formula (R1—R3)—Si—(OR2)3. Each of R2 and R3 is a C1-C6 alkyl group such as methyl, ethyl, or propyl R1 can be chosen from a wide variety of organic functional groups such as epoxy, glycidoxy, amino, and pyrrole. The most preferred silane is 3-glycidoxypropyltrimethoxysilane.

    摘要： Conductive polymers are prepared from a stabilized solution containing a monomer, an Fe(III) oxidizing agent, and a mixed solvent. The solvents are selected to stabilize the Fe(III) oxidizing agent and monomer in solution while allowing highly conducting polymers to be produced upon evaporating the lower-boiling solvent. The higher-boiling solvent does not appreciably complex with Fe(III), while the lower-boiling solvent forms a weak complex with Fe(III). The mixed-solvent system of the present invention may be used for preparing a conductive polymer counter electrode in a solid tantalum capacitor by polymerizing the monomer inside a porous tantalum pellet.
