Electropolymerization of pyrrole on a gold (Au) electrode

Abstract

A method for forming a polymerized transducer layer on an electrode, and an electrode having a polymerized transducer layer. The electrode is suitable for use in ion-selective applications. The method includes (i) combining a gold-containing electrode with an electropolymerization mixture. The electropolymerization mixture includes a doping agent and a monomer. The doping agent includes benzenesulfonic acid and / or a derivative of benzenesulfonic acid having a benzene ring with amine, hydroxyl, and / or methyl functional groups. The monomer includes a ring structure containing at least four carbons (C) and at least one nitrogen (N), sulfur (S), and / or oxygen (O). The method also includes (ii) treating the combination formed in step (i) under electropolymerization conditions sufficient to oxidize the monomer and form a polymer on the electrode.
