POLYMERIC COMPOSITION FOR FORMING CONDUCTIVE POLYMERIC LAYER OF TANTAL CAPACITOR AND PREPARING METHOD OF CONDUCTIVE POLYMERIC LAYER

摘要

Particle size is provided a polymerizable composition and a method of forming a conductive polymer cathode layer of small dopants in the conductive polymer cathode layer the covering rate of the tantalum capacitor and the electrical properties of the improved use. Polymerizable composition iron chloride (FeCl3), and the monomer in an amount of about 1mol per 2-3mol, cathode conductive polymer layer forming method of the tantalum capacitor comprising the steps of depositing a tantalum pellet is a dielectric layer formed in the polymerizable composition; Polymerizing the polymer solution is deposited on the tantalum pellet; The step of washing with pure water; The method comprising depositing the tantalum pellet having a polymer layer in the dopant solution and doped by applying electricity; And it comprises a washing step of re-resistance and dried with pure water. And preventing the peeling of the negative electrode formed of the conductive polymer layer, the coverage of the conductive cathode layer is increased. Further, the electrical characteristics and reliability, such as capacitance, loss and ESR value is increased.
