Bilayer electronically conductive polymers and process for their production
First Claim
1. An article comprising:
- an outer metal substrate; and
a coherent coating thereon comprising a bilayer, electronically-conductive film consisting of an outer film of a polycarbazole and an intermediate film of a polypyrrole in contact with said outer metal substrate.

Abstract
A film is provided herein which may be either as a coherent coating on an electrode or as an unbacked film. The film is a bilayer, electronically-conducting film comprising an outer film of a polycarbazole and a base film of a polypyrrole. The bilayer film is formed by depositing a coherent coating, consisting of a polycarbazole-on-polypyrrole bilayer film on an electrode and then stripping the bilayer film from the electrode. The electrode may be, e.g., gold, silver, copper, a platinum group metal (ruthenium, rhodium, palladium, osmium, iridium and platinum, with platinum or palladium being preferred) or a first transition series metal (e.g. iron, cobalt, or nickel). These electronically-conducting films may have catalysts absorbed therein, to exhibit catalytic behavior, or they may be used for the development of macromolecular electronics.
