Polymerization reaction coupled to charge transfer: propagation versus termination as a source of permanent travelling waves and multi-peak voltammograms

摘要: The voltammetric response for an RRC (radical–radical coupling)-initiated polymerization reaction coupled to irreversible charge transfer has been considered. Only the propagation and termination steps of polymeric chains in solution have taken into account, with exclusion any adsorption hindered diffusion effects. A set nonlinear partial differential equations is derived. It demonstrated that this possesses permanent travelling wave solutions as soon a newly defined versus balance (PTB) parameter γ greater than unity. These waves feature building uniformly moving polymer ∣ boundary film being constructed on surface under γ>1 conditions. Finally, it found conditions responsible occurrence sharp pre-peak resulting voltammograms, which thus directly connected abundant consumption monomer by polymerization. All these features are confirmed direct numerical resolution initial equations. results line, qualitatively, some were still uninterpreted, obtained electropolymerization vinylic monomers anhydrous acetonitrile. In particular, can most probably not be assigned either passivation or precipitation effects, but mere dynamical effect due itself.
