“…The PPy coated on AZ31 Mg exhibited the multiplet in the range of 1550-1600 cm −1 , this could be assigned to the existence of Mg-salicylate and the formation of PPy. The typical absorption peaks at 1375 and 1315 cm −1 corresponding to the characteristics peaks of PPy ring and C N stretching in MP-2 and MP-5 respectively [37,38]. The ATR-IR results further revealed the formation of PPy over AZ31 Mg alloy.…”

“…7). The signals at 1295, 1194 and 1039 cm À1 are attributed to polypyrrole [33,34]. The salicylate medium is the only one, of those studied in the present work, for which the presence of polypyrrole is demonstrated by IR spectroscopy at a potential as low as +0.8 V even after only one electrochemical sweep from À1 to +0.8 V. This could not have been anticipated by a simple visual examination, as the surface appears to be free of any deposit, as it appeared before being submitted to electrochemical polarization.…”

“…Meanwhile, the dense polymeric structure of PPy is also important for improving the selectivity of ions with different hydrated radii. The counterions introduced during the polymerization process can affect the growing morphology [15][16][17] as well as the redox property [8,9] of the PPy. Large organic counterions ensure homogeneous growth of PPy and the PPy membrane can be used to control cation transport.…”
