“…It is widely preferred because of its simplicity, and it can also be used as a one‐step method to form coatings on metal substrates. It allows efficient control of the chemical and physical properties of the coatings, and it can also be easily adapted to large‐scale production . The AA3004 is an essentially 96% pure aluminum alloy with minor additions for strength.…”

Poly(o‐anisidine) (POA) and poly(o‐anisidine)‐TiO2 (POA‐TiO2) nanocomposite coatings on aluminum alloy 3004 (AA3004) have been investigated by using the galvanostatic method. The electrosynthesized coatings were characterized by FT ‐ IR spectroscopy, XRD, SEM ‐ EDX and SEM. The corrosion protection performance of POA and POA‐TiO2 nanocomposite coatings was investigated in the 3.5% NaCl solution by using potentiodynamic polarization technique and electrochemical impedance spectroscopy. The results show that the corrosion rate of the nanocomposite coatings is about 900 times lower than the bare AA3004 under optimal conditions. Copyright © 2013 John Wiley & Sons, Ltd.

“…9 Electrochemical polymerisation is an attractive method for the fabrication of PPY films. 10 In this method, the pyrrole monomer, dissolved in a solvent containing anionic doping salt, is oxidised at the electrode surface by the applied anodic potential. The anion is incorporated into the polymer to ensure the electrical neutrality of the film.…”

Polypyrrole (PPY) films were electrochemically deposited on stainless steel substrates from aqueous pyrrole solutions containing p-toluene sulphonic acid and 4,5-dihydroxy-1,3-benzenedisulphonic acid disodium salt (tiron). The deposition potential of PPY in the solutions containing tiron was 0?2 V lower than that in the solutions containing p-toluene sulphonic acid. It was found that tiron can be used for the dispersion of multiwalled carbon nanotubes (MWCNTs) and fabrication of composite PPY-MWCNT films. The deposition yield was studied under galvanostatic conditions. The mechanism of PPY-MWCNTs deposition in the presence of tiron was discussed. The incorporation of MWCNTs into the PPY during electropolymerisation resulted in the formation of porous films. The films were investigated for the application in electrodes of electrochemical supercapacitors. Cyclic voltammetry data for the films tested in the 0?5M Na 2 SO 4 solutions showed a capacitive behaviour in a voltage window of 20?5 to z0?4 V versus a saturated calomel electrode. The composite PPY-MWCNT films showed improved capacitive behaviour and lower electrical resistance compared to the pure PPY films. A highest specific capacitance (SC) of 310 F g 21 was obtained at a scan rate of 2 mV s 21 for the composite films. The SC decreased with an increasing film thickness and scan rate. The cycling stability of the films was investigated. The results indicated that the PPY-MWCNT films deposited on the stainless steel substrates are promising electrode materials for electrochemical supercapacitors.

“…The widespread venture for finding different practical applications of intrinsically conducting polymers (ICPs) has discovered their use in the form of dispersion or solution as anticorrosive coatings 1–5. Among the ICPs, extensive study of the polyaniline (PAni) and its composites has been carried out because of their ease of preparation, novel properties, and potential applications 6–13.…”

Polyaniline (PAni) was synthesized by the miniemulsion polymerization and dispersed in a poly(epichlorohydrine-co-ethylene oxide) (ECO) solution. The rheological properties using an R/S Rheometer and the sheardependent electrical resistance using a homemade setup were measured. The addition of PAni particles to the ECO solution causes an increase in the shear stress and shear viscosity and the nature of flow changes from a dilatant to a Newtonian fluid. For both the ECO solution and ECOPAni mixture, the viscosity at any particular shear rate is higher during the increasing cycle of shear rate compared with the decreasing cycle of shear rate called hysteresis. The ECO-PAni mixture executes a step-like viscosity transition over the shear rate region 50-150 s À1, which is known as shear rate-induced phase transition. The resistance of ECO solution decreases with the increase in shear rate and reversibly increases with the decrease in shear rate, whereas the resistance of ECO-PAni mixture increases during both the increasing and decreasing cycles of the shear rate. The difference in resistance at zero shear rate before and after the end of shear cycle is termed as electrical set. The ECO solution and ECO-PAni mixture exhibit 4% and 79% electrical set in terms of decrease and increase of resistance, respectively. The settling process of PAni in the ECO-PAni mixture is slower compared with the pure ECO in solution. The settling time of PAni in the ECO-PAni mixture increases with the decrease in shear rate.
