の電解液を介在させて電解コンデンサが製造される。In general, electrolytic solution-type aluminum electrolytic capacitors use an anode foil with a surface oxide film formed by electrolytic oxidation, this oxide film is used as a dielectric, and a predetermined electrolyte is interposed between the current collector cathode foil and the electrolytic capacitor. is manufactured.

ンデンサの基本的な性能が影響を受けることとなる。In general, the product characteristics of electrolytic capacitors are mainly determined by the properties of the electrolytic solution interposed between the anode and the cathode in the case of electrolytic capacitors. Unlike the anode, cathode, dielectric oxide film, electrolyte, etc., the separator is not a basic component of an electrolytic capacitor, but if it is used to improve product stability and life characteristics, As a result, the basic performance of the capacitor is affected by the properties of the separator used.

きる。These indicators primarily represent the basic performance of electrolytic capacitors, or the anode, cathode, dielectric oxide film,
If the basic constituent elements of an electrolytic capacitor, such as the electrolyte calculation, are the same, it will vary to reflect the properties of the separator. Therefore, in such cases, indicators such as electrostatic capacitance (Cap), dielectric loss tangent (tanδ), and impedance (Imp) should be considered to represent the overall performance of the electrolytic capacitor, including the properties of the separator. I can do it.

維持するのが困難であった。Cellulose fibers such as manila paper and kraft paper are widely used as separators for electrolytic capacitors.
Conventionally, when a capacitor is used for a long period of time, chemical reactions occur between the electrolyte and the separator, making it difficult to maintain sufficiently stable characteristics.

原因の１つであったと考えられる。Considering the chemical properties of commonly used electrolytic solution components and conventional separator materials, chemical reactions that may occur between the electrolytic solution and the separator include, for example, the hydroxyl groups of cellulose fibers and the carboxylic acid that is a component of the electrolytic solution. Examples include an esterification reaction with. Since ions in the electrolyte are consumed by this type of esterification reaction, it is thought that such a reaction was one of the major causes of deterioration of the characteristics of the electrolytic capacitor.

However, in this type of separator, ions in the electrolyte solution are removed due to the progression of chemical reactions such as esterification between the hydroxyl groups of cellulose fibers and carboxylic acid, a component of the electrolyte solution. There is a problem in that the characteristics of the electrolytic capacitor deteriorate when used for a long period of time at high temperatures, for example.

Further, since the heterocycle-containing aromatic polymer compound having the above structure has high fiber tensile strength, it is possible to reduce the density of the separator.
