“…Polypyrrole (Ppy) is one of the most promising conducting polymers, in this respect, because of its high conductivity, stability and ease of synthesis. In fact several works have appeared [2][3][4][5][6][7][8][9][10][11][12][13] dealing with the protection of corrosion susceptible metals by electrochemically generated Ppy. However, comparatively few studies have been devoted to the study of copper protection.…”

“…Cascalheira et al [5] also reported the formation of strongly adherent polypyrrole coatings on Cu from an aqueous salicylate solution. Hien et al [12] used oxalic acid as a protective medium while Prissanaroon et al [13] reported the electropolymerisation of pyrrole on copper in aqueous dodecylbezene sulfonic acid. In addition, Bazzaoui et al [14] have shown that it is possible to deposit polypyrrole at copper by oxidizing pyrrole in an aqueous sodium tartrate solution.…”

Polypyrrole electrodeposited on copper from an aqueous phosphate solution: Corrosion protection properties

Highly adherent and homogenous polypyrrole films were electrodeposited at copper from a dihydrogen phosphate solution. The polypyrrole films were electrosynthesized in the overoxidized state by cycling the copper electrode from -0.4 to 1.8 V (SCE) in a pyrrole-containing phosphate solution. The growth of the polypyrrole films was facilitated by the initial oxidation of the copper electrode in the phosphate solution to generate a mixed copper-phosphate, copper oxide or hydroxide layer. This layer was sufficiently protective to inhibit further dissolution of the copper electrode and sufficiently conductive to enable the electropolymerization of pyrrole at the interface, and the generation of an adherent polypyrrole film.Potentiodynamic polarization measurements, Tafel analyses and open-circuit potential data revealed that the polypyrrole coating effectively protects the copper substrate from corrosion in a chloride solution. However, the corrosion protection properties were reduced with longer immersion times.

“…The presence of Cu 2+ in CuO is characterized by the two high intensity shake-up satellites appearing at ca. 10 eV higher binding energies than the main Cu 2p 3/2 and 2p 1/2 lines (933.7 and 953.4 eV, respectively) [29][30][31]. After sputtering with 2 keV Ar + beam for 10 s, these satellite structures disappeared (Fig.…”

Inherently conducting polymers (ICPs) have found widespread application as electrode materials for energy conversion and storage. The use of electropolymerization to produce such materials and structures containing them has a number of advantages including the fact that localized polymerization onto electrode structures ensures • the ability to incorporate a wide range of dopants • intimate electrical connection • spatial control • ease of fabrication of microstructures • careful control over the polymer oxidation state • the ability to form copolymers • sequential deposition to produce layered structures.In this chapter, we examine the use of electropolymerization to produce ICPs for use in solar cells (an example of energy conversion) and for polymer electrodes used in batteries and supercapacitors (energy storage). ICPs prepared via electrodeposition have also found use in catalytic electrodes for fuel cells; however, this application is not covered here.It has been widely accepted that the physicochemical and electrochemical properties of ICPs depend strongly on many factors encountered during electrodeposition [1]. These include electrochemical technique, working electrode substrate, and electrolyte [2][3][4][5]. The following considers each of these variables in turn, before the discussion is shifted to consider the application of ICPs in energy conversion and storage.
