Unidirectional Current Flow and Charge State Trapping at Redox Polymer Interfaces on Bilayer Electrodes: Principles, Experimental Demonstration, and Theory

Bilayer electrodes consist of conductive electrodes coated with or bonded to two physically discrete polymeric layers which contain two different redox substances having different E0′ values.The redox substance in the inner polymeric film next to the electrode can be oxidized or reduced by the electrode.That in the outer polymer film is constrained, by physical isolation from the electrode, to undergo oxidation or reduction only at electron energies for redox conductivity by the inner film.This arrangement leads to rectified (unidirectional) current flow.Experimental results from bilayer electrodes based on nine different combinations of redox substances in the films are presented to demonstrate the generality of the phenomenon and the ability to fabricate bilayer film.The redox substances include fixed-site redox polymers like poly2+, polyvinylferrocene, poly(4-methyl-4′-vinyl-N,N’-ethylene-2,2′-bipyridinium), and siloxane polymer of N-methyl-N”-(4-(2-(trimethylsilyloxy)ethyl)benzyl)-4-4′-bipyridinium, and (inner film) mobile redox sites like bromide, hexachloroiridate, and benzophenone.Various mechanisms are considered for bilayer electrode nonidealities which appear as a leakage of redox state trapped in the outer film, an a theory describing voltammeric properties of bilayer electrodes is compared to experimental results.
