Formation of conductive polymers using nitrosyl ion as an oxidizing agent

摘要

A method of forming a conductive polymer deposit on a substrate is disclosed. The method may include the steps of preparing a composition comprising monomers of the conductive polymer and a nitrosyl precursor, contacting the substrate with the composition so as to allow formation of nitrosyl ion on the exterior surface of the substrate, and allowing the monomer to polymerize into the conductive polymer, wherein the polymerization is initiated by the nitrosyl ion and the conductive polymer is deposited on the exterior surface of the substrate. The conductive polymer may be polypyrrole.

1. A method of forming a conductive polymer deposit on a substrate, the method comprising:
preparing a composition comprising monomers of the conductive polymer and a nitrosyl precursor, the nitrosyl precursor being a nitrite; contacting the substrate with the composition so as to allow formation of nitrosyl ion from the nitrite only on the exterior surface of the substrate, the substrate comprising a proton-donating surface or a proton-preloaded surface that serves as the only proton source used to convert the nitrite to the nitrosyl ion; and allowing the monomers to polymerize into the conductive polymer, the polymerization being initiated by the nitrosyl ion generated at the exterior surface of the substrate, and the conductive polymer being deposited only on the exterior surface of the substrate.
