“…It was clearly seen that the monomer oxidation peak was observed at the high potential region for each scan. Consequently, the upper potential limit was significant for polymer film growth in neutral medium [22,23]. It could be seen that the film growth curve recorded for poly(o-anisidine) coating produced in sodium oxalate solution exhibited similar behavior to that of poly(aniline-co-o-anisidine) film as well as polyaniline film [23][24][25][26].…”

The electrochemical synthesis of poly(o-anisidine) (POA) was achieved on brass (CuZn) electrode by applying two scan rates (50 and 20 mVs −1 ). The synthesized polymer films were strongly adherent and homogeneous in both cases. Their corrosion performance was investigated by AC impedance spectroscopy (EIS) technique, anodic polarization plots and open circuit potential-time curves, in 3.5% NaCl solution. It was clearly seen that poly(o-anisidine) films provided a significant physical protection for longer exposure time. It was shown that polymer film coated at high scan rate (CuZn/POA-H) exhibited better barrier property against the attack of corrosive agents when compared with polymer film obtained at low scan rate (CuZn/POA-L). It was found out that poly(o-anisidine) film synthesized at high scan rate caused a significant increase in corrosion resistance by its catalytic behavior on formation of protective oxide layers on the surface in longer time.

“…Kinlen et al [17] used scanning reference electrode technique to show that passivation of steel in water occurred only for ES coatings. The conducting property of PANI was also stressed by many other authors for the passivation of iron/steel [10,18,19] or copper [8,9].…”

“…In previous work, we reported that an EB/epoxy resin (ER) coating containing only 1% EB on mild steel passed 2000 h salt spray test, whereas pure ER coating stood only 600 h [6]. There are relatively few reports on PANIs for corrosion prevention of nonferrous metals like copper [7][8][9][10]. Brusic et al [7] showed that spin-coated EB and its derivatives films reduced the corrosion rate of copper in water by a factor of at least 50.…”

“…The literature dealing with the synthesis of PANI by different methods like solution, emulsion, miniemulsion, microemulsion, inverse miniemulsion, electrochemical [26,27] and conduction mechanism [28,29] are very well studied. But the literature dealing with aniline and o-anthranilic acid copolymer is relatively less.…”

Copolymers of aniline and o-anthranilic acid (PANAA)/kaolinite clay composites were synthesized by 5:1 molar ratios of the respective monomers with different percentages of kaolinite clay particles via in situ chemical co-polymerization. The spectral characteristics of the resulting copolymers were investigated. The results were justified by measuring the UV-Vis absorption spectra, FT-IR for PANAA copolymer, and the in situ PANAA/kaolinite clay composite. The thermal gravimetric analysis for the isolated copolymer powder in absence and in presence of kaolinite clay was carried out. Moreover, the morphology of the polymer clay composites system was studied by the scanning electron microscope micrographs at different magnifications. X-ray diffraction was used to measure the nature of the copolymer and extent of crystallinity present in the neat copolymer and copolymer/kaolinite composite materials.
