“…The result is interpreted taking also into account the stabilization of the oxide film by a substrate/poly mer interaction at these positive potentials and over oxidation of the polymer [29]. According to literature data, the curves are characterized by the appearance of current peaks in the active and transpassive regions in both, nearly neutral [16] and alkaline [17] solutions. The first potential region is mainly related to the iron redox processes of Fe/Fe(II) and Fe(II)/Fe 3 O 4 .…”

“…Good adhesion on surface of the poly mer film depends on interaction between the metallic surface and the inner surface. Therefore electropoly merization plays a major role in developing a passive film on the surface [17]. The oxidized and reduced state of the PPy polymer involves the n electron sys tem in the aromatic ring and movements of the doping anions in and out of the film.…”

“…It can be chemically or electrochemically deposited on a metal surface from organic and aqueous media [7][8][9][10][11][12][13][14][15][16]. Several studies reported the capacity of PPy as coating against corrosion of oxidizable metals.…”

“…Por ello se observan altos valores de rugosidad para polyTOH por AFM (Fig. 5.28) y estructuras tipo coliflor [204]. La estructura abierta de la película de polyTOH podría permitir el transporte de cargas eléctricas necesarias para oxidar nuevas especies solubles (monómeros, dímeros y oligómeros).…”
