“…SEM was used to probe the micromorphology of the sample, and the synchronous elemental analysis was also performed to gain the insight into the chemical element components, as shown in Figure . As expected, TsONa‐doped PPy formed as the irregular microspherical particles, with an average particle size of about 3 μm, as shown in Figure (a) . Clearly, such a scraggy surface may have endowed the sample with a large surface area.…”

In this study, p-toluene sulfonate (TsONa) doped polypyrrole (PPy) was synthesized for an anode in a lithium-ion battery via a one-step facile electropolymerization on Fe foil. The obtained TsONa-PPy-Fe composite electrode was investigated with scanning electron microscopy, energy-dispersive X-ray spectroscopy, Fourier transform infrared spectroscopy, and galvanostatic chargedischarge profiling. As expected, many irregular microspherical particles of TsONa-doped PPy formed and combined tightly with the surface of Fe foil. Furthermore, the obtained TsONa-PPy-Fe anode also delivered satisfactory electrochemical performances. For example, the reversible capacity was still about 105-115 mAh/g, even after at least 50 cycles. The high lithium storage activity of PPy and the high conductivity of the TsONa-doped PPy jointly contributed into the satisfactory electrochemical performances. V C 2017Wiley Periodicals, Inc. J.

“…Application of polypyrrole coatings as a corrosion protective layer has been investigated for various metals including steel, [5][6][7][8][9][10][11][12][13] magnesium, [14][15][16][17] and aluminum alloys. [18][19][20][21][22][23][24][25][26][27][28][29][30][31][32][33][34] The corrosion protection mechanism of polypyrrole coatings can be attributed to several phenomena including (i) passivation of the substrate by the conductive polymer as an oxidizer, and (ii) shifting the oxygen reduction site from the substrate/coating to the coating/electrolyte interface.…”

Effect of solution chemistry on the electropolymerization and the electrochemical properties of polypyrrole coatings on aluminum is studied by means of electrochemical techniques, scanning electron microscopy (SEM), and x-ray photoelectron spectroscopy. It is shown that the protection effect of the coating in long-term exposures and when exposed to more concentrated NaCl solutions depends on the chemistry of electropolymerization electrolyte. The results show that nitrate anions passivate the aluminum substrate during the electropolymerization process. The resulting coating is less prone to blistering in a NaCl solution and probably due to its higher electrochemical activity presents a higher anodic protection effect. The galvanic interaction of polypyrrole coating with aluminum in a NaCl solution is directly observed using focused ion beam-assisted SEM.

“…The use of polymers is one of the most important strategies to improve the corrosion resistance [255][256][257][258]. Surface irregularities and anomalies, such as roughness or pores, present a different surface energy that make them favorable polymerization centers [259,260].…”
