“…[13][14][15][16][17][18][19] Mengoli et al 20 were the first to examine the protective behavior of polyaniline (PANI) on stainless steel, and then in 1985, DeBerry 21 showed that electrochemically synthesized PANI acts as a corrosion-protection layer on stainless steel in 1M H 2 SO 4 . Since then, several research groups [22][23][24][25][26] have systematically investigated the electrochemical syntheses of various conducting polymers on oxidizable metals for corrosion protection. The common feature of these investigations is that the electrochemical synthesis of conducting polymer coatings on oxidizable metals is preceded by the dissolution of the base metal at a potential lower than the oxidation potential of the monomer.…”

Strongly adherent poly(aniline-co-o-toluidine) coatings were synthesized on low-carbon-steel substrates by the electrochemical copolymerization of aniline with o-toluidine with sodium tartrate as the supporting electrolyte. These coatings were characterized with cyclic voltammetry, ultraviolet-visible absorption spectroscopy, Fourier transform infrared spectroscopy, nuclear magnetic resonance spectroscopy, and scanning electron microscopy. The formation of the copolymer with the mixture of monomers in the aqueous sodium tartrate solution was ascertained by a critical comparison of the results obtained from the polymerizations of the individual monomers, aniline and o-toluidine. The optical absorption spectrum of the copolymer was drastically different from the spectra of the respective homopolymers, polyaniline and poly(o-toluidine). The extent of the corrosion protection offered by poly(aniline-co-o-toluidine) coatings to low-carbon steel was investigated in aqueous 3% NaCl solutions by opencircuit-potential measurements and a potentiodynamic polarization technique. The results of the potentiodynamic polarization measurements showed that the poly(anilineco-o-toluidine) coatings provided more effective corrosion protection to low-carbon steel than the respective homopolymers. The corrosion rate depended on the feed ratio of o-toluidine used for the synthesis of the copolymer coatings.

“…Recently many attempts have been carried out to protect the aluminium and its alloy by organic base coating. Ogurtsov et al (2004) have reported the protection ability of pure undoped PANI (emeraldine base) and PANI doped with p-toluene-sulfonic (TSA), camphorsulfonic (CSA) and dodecylbenzenesulfonic (DBSA) acids coatings for Al 3003 alloy. As it can be seen from their results, Table 1, that the highest protecting ability factor was obtained for undoped PANI being equal to 12 and 4.4 in neutral and acidic media, respectively.…”

“…In the last four decades, conducting polymers (CPs) have gained a special status owing to wealth of applications [5][6][7][8]. shielding and microwave absorption properties of these polymers can be explained in terms of electrical conductivity and presence of bound/localized charges (polarons/bipolarons) leading to strong polarization and relaxation effects [9,10].…”

In this research (PANI/CNT) core/shell nanocomposite were synthesized via in situ chemical oxidative seeding polymerization‚ the results of SEM indicated the structure of synthesized nanocomposite. TEM‚ FTIR‚ UV-Vis‚ XRD analyses of samples showed that this nanocomposite is decorated with (Fe‚ Co) oxide nanoparticles. The VSM test of as prepared and annealed nanocomposite exhibited the saturated magnetization of 1.1 and 3.86 emu/g, respectively; the coercivity values were also − 350 and − 110 Oe, respectively. The reflection loss characteristics of (Fe‚ Co) oxide-Pani-CNT core/shell nanocomposite were also investigated with a vector network analyzer‚ in the 8.2-12.4 GHz range (X band). The maximum absorption increases with enhancement of the dispersed nanoparticles percent in polyurethane matrix from 1 to 10%. The value of the maximum reflection loss in the absorption samples with 1 and 10% of nanoparticles is − 2.14 dB at 9.33 GHz and − 7.32 dB at 11.97 GHZ, respectively.
