| titleOfInvention | Method for preparation of solubility polypyrrole electrolyte |
| abstract | The present invention relates to electrolytic capacitors, such as tantalum electrolytic capacitors and aluminum electrolytic capacitors, by dissolving a polypyrrole of a conductive polymer polypyrrole or a coupling agent and a polypyrrole containing 0.01 to 10 wt% of a surfactant in protonic solvents and organic acids. A method for producing a polypyrrole electrolyte for use. The polypyrrole electrolyte prepared above is dipped in oxidized tantalum and coated with carbon paste and silver paste to prepare a tantalum electrolytic capacitor. The proton solvent is preferably a solvent of -OH, -SO 3 H, -COOH, -NH functional group capable of hydrogen bonding with oxidized tantalum, and the coupling agent is alkoxysilanes (alkoxysilanes), arylsilanes (allylsilanes) Preferably, the surfactant is a zwitterionic surfactant and an anionic surfactant. According to the present invention, it is economical because it is excellent in thermal air stability in air and dipped in an electrolyte solution and coated and dried, and thus it is possible to uniformly coat the inside of tantalum and exhibit stable capacitance characteristics regardless of frequency. In addition, the present invention provides a method for producing a soluble polypyrrole electrolyte for an electrolytic capacitor, which can develop an ideal low impedance, high-capacity tantalum electrolytic capacitor in a high frequency band (100KHz to 10MHz). |
