Corrosion inhibition of mild steel in hydrochloric acid solutions using electropolymerized Poly 2-aminobenzothiazole, P(2ABT), was evaluated using weight loss, potentiodynamic polarization and electrochemical impedance spectroscopy measurements at different temperature. Results showed that the inhibition efficiency increases with increasing the concentration of P(2ABT) up to 12.7 9 10 -6 mol L -1 and decreases with raising the temperature. Polarization curves indicate that the studied compound acts as anodic inhibitor. Thermodynamic activation parameters for both dissolution and adsorption processes are calculated and discussed as well as the adsorption isotherms are calculated. Gibbs free energy value confirms the physical nature of the adsorption, also the mechanism of inhibition is discussed. Scanning electron microscopy is used to study the surface morphology of mild steel in hydrochloric acid solution in the absence and presence of 12.7 9 10 -6 mol L -1 P(2ABT). Data obtained from all techniques are in a good agreement with each other.

“…Many of organic compounds as electroactiveconducting polymers [7][8][9][10], carboxylic organic acids [11,12], fatty acids [13], dicyandiamide and some of its related compounds [14], hydrazine compounds [15], triazole and thiazole derivatives [16], were also found to inhibit the corrosion of aluminum. Sayyah et al [17,18] studied the inhibition effect of the series of the prepared monomeric surfactants and their analog polymers with different hydrophilic side chain length on the corrosion of aluminum in acid medium. Results indicate that the hydrophilic side chain has remarkable influence on the inhibition efficiency of the prepared surfactants and the inhibition efficiency increases in both monomeric and polymeric surfactants as the length of the side chain increases.…”

Inhibition effect of poly 3-dodecyloxy aniline polymeric surfactant (PC 12 H) on the corrosion of aluminum in 0.5 M HCl solution was investigated using potentiodynamic polarization technique under different experimental conditions. Inhibition efficiency and thermodynamic functions for dissolution and adsorption of PC 12 H are compared with Poly 3-(dodecyloxy sulfonic acid) aniline (PC 12 SO 3 H) to explain the effect of terminal side chain on the corrosion protection. Data show that the presence of-SO 3 H as a terminal group in PC 12 SO 3 H decreases the inhibition efficiency from 88.7%, in case of PC 12 H, to 55.1% in case of PC 12 SO 3 H. Quantum chemical calculations were performed on PC 12 H and PC 12 SO 3 H to investigate the relationship between the molecular structures and their inhibition efficiencies.

“…Umoren et al [71] elucidated the corrosion inhibition mechanism of aluminum in H 2 SO 4 solution by polyacrylic acid (PAA) in the absence and presence of iodide ions by using in-situ atomic force microscopy (AFM) technique. Results obtained indicated that PAA inhibited the corrosion of aluminum by adsorption onto the aluminum surface.…”

Abstract:The use of corrosion inhibitors is the one the most economical and practical means of controlling metallic corrosion in different corrosive media. Interest on the use of eco-friendly organic compounds as corrosion inhibitors has extended to the use of polymers to inhibit metallic corrosion. The use of polymers as corrosion inhibitors has attracted attention and has gained wide acceptance in recent times. This has been attributed to a number of factors namely: (i) they are low cost and stable to metallic materials in acid media, (ii) they possess multiple adsorption sites, (iii) through their functional groups, they form complexes with metal ions and on the metal surface these complexes occupy a large area, thereby blanketing the surface and protecting the metal from corrosive agents present in the solution. A number of synthetic and natural polymers as metallic corrosion inhibitors have been investigated and reported. As an update to previous review work on the use of polymers as corrosion inhibitors, the present review presents most of the contributions made to the literature on the use of polymers as corrosion inhibitors of diverse metals in different corrosive media in the last four (2010)(2011)(2012)(2013) years.
