The potentiodynamic synthesis and subsequent characterisation of a polyaniline (PAn) grown in the presence of a water-soluble conducting polymer, poly(2-methoxyaniline-5-sulfonic acid) (PMAS) is described. The novel polymer is obtained as a water-insoluble film consisting of a PAn backbone with PMAS integrated as the molecular dopant. The electrodeposition of the polyaniline material is enhanced by the presence of the electrically conducting, PMAS polyelectrolyte dopant, which functions as a molecular template providing supramolecular pre-ordering as well as simultaneously facilitating charge transport during electrodeposition.

Summary: The electrochemical performance of platinum electrodes was evaluated in vitro and in vivo, and the study found that electrode polarization significantly affected the electrochemical response. Initial in vitro measurements were not good predictors of subsequent measurements in vitro or in vivo. Electrode implantation affected the electrochemical impedance, with lower frequencies being more dependent on electrode properties and higher frequencies being dependent on solution properties.
