Abstract
A conducting polymer film has an insulating polymer film as a base, and a conducting aromatic polymer compound is contained by electrochemical polymerization in at least part of the insulating polymer film.
Claims28
A method of manufacturing an electrically conducting polymer film comprising the step of providing an insulating polymer film on the surface of an electrode;
- causing electrolyte solution and aromatic polymer to reach said electrode surface through said insluating polymer film;
- electrolytically polymerizing said aromatic polymer at the interface between said electrode and said insulating polymer film;
- and forming an electrically conducting aromatic compound area from said interface of said insulating polymer film toward the inner side of the insulating polymer film.
A polymer film made in accordance with the method of any one of the preceeding claims.
