Title:
CONDUCTIVE POLYMER TERMINAL AND SOLID ELECTROLYTIC CAPACITOR
Document Type and Number:
Japanese Patent JP3201466
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide excellent water resistance and moisture resistance, by connecting a conductive polymer to a metal via a region having a rectifying operation, and setting a direction of the operation in a forward direction from the metal toward the polymer.
SOLUTION: A conductive polymer 2 is a conjugate polymer compound containing dopant made of electron attractive compound. A metal 1 is not particularly limited if it is metal or alloy in which a current can flow but is preferable particularly to having a negative standard electrode potential in view of effects of heat resistance and moisture resistance. A water channel 4 is with water in contact with both the polymer 2 and the metal 1. The polymer 2 is connected to the metal 1 via a region having a rectifying operation. A connecting method is not particularly limited in its shape if a direction of the rectifying operation is forward from the metal 1 toward the polymer 2, i.e., a current flows when the metal 1 is a positive potential and the polymer is a negative potential, and the current scarcely flows on the contrary when the metal 1 is a negative potential and the polymer 2 is a positive potential.
