“…The resulting electronic system has in general either a quasi-one-or twodimensional character, resulting in a specific electronic conduction ranging from insulating semiconducting to a highly conducting phase. The multiplicity of intraand intermolecular vibrational modes in conjugated polymers are the key for the many exciting properties, leading to numerous technological applications, such as active electrode materials in energy storage [11], optoeletronic devices [12], display devices [13], corrosion inhibitors [14] or controller of electromagnetic radiation and electrostatic charge [15,16]. Conducting polymer composites have been developed with a wide range of exciting properties for applications in films, fibers and coatings.…”

A conducting composite of poly(o-anisidine), poly(o-toluidine) and poly(o-anisidine-co-o-toluidine) using incorporation of TiO 2 and SiO 2 was prepared by electrochemical polymerization. The films were electropolymerized in solution containing 0.1 M monomer(s), 1 M sulphuric acid as supporting electrolyte and 10 −5 M TiO 2 and SiO 2 by applying a sequential linear potential scan rate of 50 mV/s between −0.2 and 1.0 V versus an Ag/AgCl electrode. The characterization of the composites was done by cyclic voltametry, UV-Vis spectroscopy, electrical conductivity and thermogravimetric analysis. It is observed that the UV-Vis peaks appear in the region of the conducting emerladine salt (ES) phase. Overall, the polymers prepared using TiO 2 have higher conductivity than SiO 2 , with poly(o-toluidine)-TiO 2 conducting composite having the highest conductivivty. The composite does not lose its colour at higher temperature and, hence, can be utilized as conductive pigments required for anti-electrostatic applications.

“…The corrosion inhibition property of low molecular weight straight chain amines for steel corrosion has also been studied [20]. Recently, ortho-substituted anilines [21] and polyanilines [22,23] have also been studied. In this paper, the inhibition effect of diethanolamine on the corrosion of iron in 0.5 M H 2 SO 4 is discussed.…”

The inhibitory effect of diethanolamine (DEA) on corrosion of mild steel in 0.5 M H 2 SO 4 was investigated by various corrosion monitoring techniques. Galvanostatic polarization study revealed that this compound is a very good inhibitor. The inhibition efficiency (I%) varies in the range of 88.7% to 55.3 % for a concentration range of 10 -3 M to 10 -7 M at 303 K, respectively. A study of corrosion potential (E corr ) reveals that DEA is a mixed type inhibitor. DEA inhibited mild steel corrosion due to physical adsorption of the inhibitor on the metal surface. The study at higher temperatures indicates that the inhibition efficiency decreases with the increase in temperature. The adsorption of DEA on the mild steel surface in 0.5 M H 2 SO 4 follows the Frumkin's adsorption isotherm. The results of potentiostatic polarization study revealed that DEA is a strong passivating additive. The results of infra red (IR) spectroscopy, scanning electron microscopy (SEM) and quantum chemical study supplement the results of the electrochemical techniques.

“…In recent times, conducting polymers have received considerable attention as corrosion protective coatings for oxidizable metals. It is now well-known that electrochemical polymerization is an effortless and most suitable method for corrosion protection [13][14][15][16] . The present work deals with the electro polymerization of PICA coating on LN SS in 0.5 M H 2 SO 4 medium.…”

Poly(indole-5-carboxylic acid) (PICA) has been synthesized by electrochemical polymerization technique from different concentration of poly(indole-5-carboxylic acid) using lithium per chloride as oxidation agent at different scan rate. The as-synthesized PICA was characterized using Fourier transform infrared spectroscopy (FT-IR) and Proton nuclear magnetic resonance spectroscopy ( 1 H-NMR). Thermal analysis of the PICA was performed by Thermo gravimetric analysis (TGA). The corrosion protection performance of low nickel stainless steel (LN SS) specimens coated with 0.1 M concentration of PICA was investigated in 0.5 M H 2 SO 4 medium using potentiodynamic polarization and electrochemical impedance spectroscopic (EIS) methods. The morphological properties of the polymer were characterized by scanning electron microscopy (SEM). The as-synthesized PICA has been used in order to achieve adherent, as well as environmentally preferential good anti-corrosive coating. Electrochemical corrosion tests and surface analysis results evidently showed that PICA coating served as a stable mass matrix on LN SS against corrosion. It was also revealed that the coating of PICA at 0.1V scan rate with 0.1M indole-5-carboxylic acid exhibited the best corrosion resistance among all concentrations.
