Abstract
Method of manufacturing a conductive composition precursor prepared by dispersing or dissolving at least one additive having high dielectric layer repairing ability in conductive polymer solution, the conductive composition made by removing a medium or solvent from this composition precursor. The additive is at least one of “phosphoric acid or phosphoric acid ester compounds”, “phenol or phenol derivatives”, “nitrobenzene derivatives”, “alkyl or naphthalene sulfonic acid anion”, “fluorocarbon surface active agent” and “fluorocarbon surface active agent and binder.”
