• Resumen

  • Considering that electropolymerization process occurs via radical intermediates, it was used a stable nitroxide radical such as TEMPO, with the aim to stabilize the species generated in the electrode/solution interface. The obtained results show that TEMPO really acts as a "radical trapping". Therefore, applying an adequate electrochemical perturbation it should be possible the progressive elongation of polymeric chains, and with that, the control over the structure and polydispersity of the deposit
