“…The third approach involves the use of copolymerization to prepare new polymers with inbuilt tailor-made properties suitable for the application. More recently, Bereket et al [25] reported the electrochemical synthesis of poly(aniline-co-2-anisidine) films on stainless steel in tetrabutylammonium perchlorate/acetonitrile solution containing perchloric acid. They investigated the corrosion properties of these copolymer coatings in 0.5 M hydrochloric acid solution by potentiodynamic technique, open circuit potential measurements and electrochemical impedance spectroscopy.…”

“…The use of conducting polymers as advanced coating materials for the corrosion protection of oxidizable metals has become one of the most exciting new research fields in recent times. [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.…”

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.

“…Conducting polymers such as polyaniline (PANI), polypyrrole (Ppy) and polythiophene (PTh) exhibit good electrochemical activity and constitute an important class of materials for pseudo-capacitors, rechargeable lithium batteries, sensor devices, flexible display panels, organic light emitting diodes, sensitive films for environment monitoring and corrosion protective coatings [1][2][3][4][5][6][7]. As compared to conventional conducting polymers, nanostructured conducting polymers display improved performance in technological applications.…”

The present work reports the synthesis and characterization of nanostructured poly (o-toluidine) (POT) reinforced epoxy-siloxane (ES) composite resins. The structural elucidation was carried out using FT-IR and UV-visible spectrometry. The FT-IR analysis confirmed the interaction between NH group of the POT and the OH group of ES via strong hydrogen bonding. The UV-visible spectra of POT/ES composites revealed a blue shift of 100 nm in the polaronic transition peak observed at 600 nm in pristine POT, which was attributed to the restriction in the delocalization of polarons in the POT chains due to electrostatic interaction via hydrogen bonding. The nanosize of POT and its dispersion in the ES matrix was confirmed by X-ray diffraction (XRD) and transmission electron microscopy studies. The particle size was found from 15-35 nm. The morphological studies confirmed the formation of a nanocomposite where POT appeared to act as reinforcing agent in the ES matrix. XRD showed the semi-crystalline nature of POT/ES nanocomposites. The conductivities of POT and its nanocomposites were 10 -3 -10 -4 S/cm at 30°C. The thermal stability increased with an increase in the loading of POT in ES. The nanocomposites revealed good physico-chemical and physicomechanical characteristics, which suggests their potential application as corrosion protective coatings.
