Abstract

A method for preparing electroconductive polymer solution comprises the steps as follows: in the procedure of preparing the electroconductive polymer solution from monomer mixed solution containing electroconductive polymers, an emulsion procedure is adopted to improve the conductivity of the electroconductive polymers so as to obtain the electroconductive polymer with high conductivity. The coating film of the polymer solution has high conductivity and transmission and low resistance. When the coating film is used for the solid electrolyte of a solid electrolytic capacitor, favorable performances such as low ESR and the like can be achieved.
