For 24 hours. To 50 g of the prepared polythiophene solution, erythritol (5 g), pentaerythritol (1.25 g) and boric acid (1.0 g) were added and stirred at room temperature for 24 hours for complete dissolution. Thereby, a conductive polymer solution was obtained.
- Example 2 A conductive polymer solution was prepared in the same manner as in Example 1 except that erythritol (5 g) and boric acid (1.0 g) were added to 50 g of the polythiophene solution produced in the same manner as in Example 1. A polymer film was prepared.

By this cross-cut test method, the adhesion of the conductive polymer film was evaluated.

The water resistance of the conductive polymer film was evaluated by this tap water immersion method.
- Table 1 compares the adhesion and water resistance of the conductive polymer films in Examples 1 to 4 and Comparative Example 1. From Table 1, it can be seen that the adhesion and water resistance of the conductive polymer films of Examples 1 to 4 are superior to those of Comparative Example 1.

- peeling and swelling were not observed in the examples of the present invention, it can be seen that the resin was uniformly formed.
- Example 5 An anode body composed of a 3 ⁇ 4 mm porous aluminum foil subjected to surface expansion by etching, a monomer solution obtained by dissolving 10 g of pyrrole as a monomer in 200 ml of pure water, and p-toluenesulfonic acid as a dopant and an oxidizing agent It was alternately immersed in a solution in which 200 g of iron (III) salt was dissolved in 200 ml of pure water and pulled up. This was repeated 10 times, and chemical oxidative polymerization was performed to form the first conductive polymer compound layer 3A.
- Example 2 the conductive polymer solution prepared in Example 1 was dropped onto the first conductive polymer compound layer 3A, and then subjected to a condensation polymerization reaction in a 90 ° C. constant temperature bath. Furthermore, the temperature of the thermostatic bath was set to 125 ° C. and dried and solidified to form the second conductive polymer compound layer 3B. Thereafter, a graphite layer and a silver-containing resin layer were sequentially formed on the second conductive polymer compound layer 3B to manufacture a solid electrolytic capacitor.
- Example 6 A solid electrolytic capacitor was produced in the same manner as in Example 5 using the conductive polymer solution prepared in Example 2.
- Example 7 A solid electrolytic capacitor was produced in the same manner as in Example 5 using the conductive polymer solution prepared in Example 3.
- Example 8 A solid electrolytic capacitor was produced in the same manner as in Example 5 using the conductive polymer solution prepared in Example 4.
- Comparative Example 2 A solid electrolytic capacitor was produced in the same manner as in Example 5 using the conductive polymer solution prepared in Comparative Example 1.
- ESR of the solid electrolytic capacitors manufactured in Examples 5 to 8 and Comparative Example 2 was measured and evaluated.
- ESR was measured using an E4980A Precision LCR meter (trade name, manufactured by Agilent Technologies) at 100 kHz.
- ESR evaluation is based on the ESR increase rate obtained by dividing ESR after standing for 500 hours in an environment of temperature 60 ° C and humidity 95% by ESR before leaving, and comparing the ESR increase rate of each solid electrolytic capacitor I went there.
- Table 2 compares the ESR increase rates of the solid electrolytic capacitors manufactured according to Examples 5 to 8 and Comparative Example 2. From Table 2, the ESR of Comparative Example 2 increased 8.0 times when left in a high humidity environment. On the other hand, the ESR increase rate of Examples 5 to 8 is 1.7 to 3.0 times, and it can be seen that the increase in ESR is suppressed. This indicates that the solid electrolytic capacitor according to the present invention is excellent in the adhesion between the anode body and the solid electrolyte layer and the water resistance of the solid electrolyte layer. Moreover, it is also consistent with the evaluation results of water resistance of the conductive polymer material in Table 1. That is, the solid electrolytic capacitor using the conductive polymer material according to the present invention has excellent moisture resistance.
- the ESR increase rate of Examples 7 and 8 is 1/4 or less that of Comparative Example 2, and the ESR increase rate is greatly suppressed.
- the solid electrolyte layer contains a hydrophilic resin so that the cross-linked structure and the straight chain structure cross each other, and the adhesion between the anode body and the solid electrolyte layer and the water resistance of the solid electrolyte layer are further improved. It depends.
