Electrochemically prepared poly(3‐methylthiophene) films on both platinum and 430 stainless steel (430SS) rotating disk electrodes (RDEs) were characterized for various galvanostatic electropolymerization conditions. Both applied current density and rotation rate affected subsequent redox capacity, polarization and self‐discharge behavior of the films in 1N sulfuric acid solution. Poly(3‐methylthiophene) films were galvanically coupled to polished 430SS RDEs in 1N sulfuric acid solution to evaluate their effectiveness in stabilizing the steel in a passive state.
