Conductive polymer dispersion for capacitor and capacitor packaging structure

Abstract

The invention provides a conductive polymer dispersion for a capacitor and a capacitor packaging structure. The invention discloses the conductive polymer dispersion for the capacitor. The conductivepolymer dispersion comprises a conductive polymer, a dispersant and an additive, wherein the conductive polymer dispersion is tested by an ultraviolet-visible spectrometer to obtain a transmission spectrum which has a first characteristic peak between 350 nm and 450 nm and a second characteristic peak between 300 nm and 400 nm. The conductive polymer dispersion can be effectively applied to the electrode body of the capacitor so that the electrical characteristics of the capacitor packaging structure can be improved.
