“…Figure 11a illustrates how the polymer was formed along the lines of the substrate, showing a globular morphology of sizes ranging from 4 to 5μm with a few smaller outer cores on the surface, which are highlighted on the entire matrix of the polymer. This globular morphology, as previous reported, is typical of polypyrrole when formed by electropolymerization either by potentiostatic or galvanostatic methods (Lehr and Saidman, 2007;Lu et al, 2006;Martins et al, 2008;Nie et al, 2008). In Figures 11b and 11c the same globular morphology is observed.…”

Abstract:Polypyrrole films were electrosynthesized potentiodinamically on transparent fluorinedoped tin dioxide (FTO) substrates. Polymerization was carried out in the presence and in the absence of sodium dodecylbenzenesulfonate (SDBS) and single-walled carbon nanotubes (SWCNTs). The effect of the presence of SDBS and the addition of both asgrown and air-oxidized SWCNTs to the polymerization solution was studied. .

“…Puede apreciarse que se ha formado sobre el acero inoxidable siguiendo las líneas del pulido del sustrato, presentando una morfología globular de tamaños que oscilan entre 4-5µm, con algunos núcleos exteriores más pequeños sobre la superficie de los glóbulos grandes, los cuales se resaltan sobre toda la matriz del polímero. Esta morfología globular, según trabajos anteriores, es típica del polipirrol cuando se forma por electropolimerización [36][37][38]. En la micrografía de la Figura 7b se puede apreciar una distribución heterogénea del PPy sobre la superficie del sustrato, dado que no se presenta una geometría definida.…”

The fuel cells are new alternatives for energy production with low environmental impact. Nowadays, conducting polymers are considered the most promising material to manufacture these type of cells because of their easy application and operation, being polypyrrole (PPy) one of them. The electrochemical synthesis of single-layer polypyrrole and two-layers or multiple-layers polypyrrole/platinum (PPy/Pt) films is reported in this paper. The films were obtained by electropolymerisation of pyrrole and cathodic deposition of platinum from ammonium hexachloroplatinate salt on stainless steel 304. The composition, morphology, conductivity and the electrochemical properties of the films were study by Raman Spectroscopy, SEM, Profilometer, impedance and cyclic voltammetry. The possible use of PPy and PPy/Pt films as electrodes for fuel cells is also discussed.Keywords: polypyrrole/platinum, conducting polymers, cyclic voltammetry. IntroducciónLos polímeros conductores son un tipo de materiales que tienen comportamiento redox, además de propiedades combinadas de metales y plásticos. Estos han sido estudiados por sus potenciales aplicaciones como: dispositivos para almacenar carga, materiales para baterías, celdas solares, electrodos modificados, recubrimientos anticorrosivos y transistores moleculares, entre otras [1,2]. Estos polímeros se perfilan como materiales prometedores para la fabricación de celdas de combustible en términos de su aplicación y operación, siendo el polipirrol (PPy) uno de ellos. El PPy presenta alta conductividad eléctrica, estabilidad térmica, resistencia a la oxidación, es de fácil obtención, puede formarse a partir de disoluciones acuosas y en disolventes orgánicos [3]. Además puede obtenerse por polimerización química o electroquímica considerando que la electropolimerización proporciona un mejor control del espesor y de la
