Embodiment 1

[0026] According to the proportions listed in Table 1 below, the listed oxidant such as iron (III) tosylate iron (III) methanesulfonate iron (III) is dissolved in a solvent such as ethanol or n-butanol to form an oxidant solution, and 3,4-ethylenedi Oxythiophene (EDT) monomer is prepared into a monomer solution with a solvent, and then the prepared oxidant solution and the monomer solution are mixed, and ultrasonic waves are used to vibrate the solution to fully mix the solution, and the mixed solution is measured at room temperature (20°C). The saturated vapor pressure of the solution is to make the saturated vapor pressure of the solution below 1000 Pa, and the change of the turbidity of the polymerization liquid over time is measured, and the results are shown in Table 2.

[0027] For each of the prepared polymerization solutions, the oxidative polymerization test was carried out according to the following steps: 1) Clean the 20×50mm glass slides with deionization and dry th...

Embodiment 2

[0034] A sintered block of tantalum powder with a specific volume of 50,000 μF / g and a size of 4.3×3.1×1.1 (mm) was anodized in a 0.1wt% (weight percent) phosphoric acid solution, and the working voltage of the anodization was 33V. After anodizing, the agglomerate is boiled, washed and dried to form the capacitor core. Prepare the polymer solution with the 5# formula in Table 1, soak the above capacitor core in the polymer solution for 5min-10min, then place the tantalum core soaked in the polymer solution at room temperature to dry for about 10min, and then place it at 40℃- React in an oven at 60°C for 15 minutes, and then heat-treat at 120°C for 10 minutes. Then wash the core with deionized water for 30 minutes, repair the anode tantalum core in 0.1wt% p-toluenesulfonic acid aqueous solution for 30 minutes, then rinse and dry in deionized water, and then immerse and dry as described 5 times , heat treatment and supplementary forming process.

Abstract

The invention relates to a formula and an application of conducting macromolecular polymer liquid which can be steadily stored for a long time in the normal temperature, wherein the polymer liquid comprises conducting macromolecular monomers, dopant, two or more than two oxidants with different balancing anion, mixture oxidant solution which is prepared by two or more than two kinds of dissolvent with different boiling points. The polymer liquid is characterized by being steadily stored for a long time in an indoor temperature condition, and the polymerization reaction can not occur. The electrical conductivity of conducting high polymer film which is prepared by the polymer liquid is good, the equivalent series resistance is very low, and the high-temperature thermal property is stable. When the conducting high polymer film which is prepared by the polymer liquid is used as a cathode layer of a solid electrolytic capacitor, the equivalent series resistance (ESR) and the leakage current of the electrolytic capacitor can be obviously reduced, thereby the solid electrolytic capacitor with very low ESR, low leakage current and good characteristics in the high-temperature condition can be obtained.

Description
