Abstract
A novel activation/etch method is disclosed for conductive polymer substrates and conductive polymer composite substrates to achieve good adhesion to subsequently applied coatings. The method in a preferred case involves anodically polarizing conductive polymers/polymer composites in aqueous etching solutions.
