“…The morphology of the carbon steel surface before and after 24 [29], and the Minimal Inhbitory Concentration value determined experimentally respectively. The literature CMC value was also chosen for its known corrosion inhibition efficiency [18].

“…In solutions with surfactant concentrations above the CMC, micelles are thermodynamically stable and equilibrium with monomers (Figure 1b.). The highest corrosion inhibiting efficiency is obtained at concentrations close to the CMC [17,18]. Initially, the surfactant molecules adsorb at the solution / metal interface, reducing the surface tension and forming a protective monolayer.…”

“…Gemini surfactants are now recognised as multifunctional compounds, because of their many applications: e.g. detergents, solubilisers, biocides, and disperser agents, and now more recently, corrosion inhibitors [14,[17][18][19][20][21]. Cationic surfactants are very efficient inhibitors because the positive charge causes strong attachment to metal surfaces [12,14,18,25].…”

Biocorrosion is an important type of corrosion which leads to economic losses across oli and gas industries, due to increased monitoring, maintenance, and a reduction in platform availability. Anaerobic sulfate reducing bacteria (SRB) are known to accelerate the rate of corrosion tenfold, by secreting specific enzymes. Mitigation strategies include: (i) cleaning procedures; (ii) addition of microbiocides; (iii) antifouling coatings and (iv) cathodic protection. Ideally, a chemical compound engineered to mitigate against biocorrosion would possess both antimicrobial properties, as well as efficient corrosion inhibition. Gemini surfactants have shown efficacy in both of these properties, however there still remains a lack of electrochemical information regarding biocorrosion inhibition. The inhibition of corrosion and biocorrosion, by cationic gemini surfactants, of carbon steel was investigated. The results showed that the inhibition efficiency of the gemini surfactants was high (consistently > 95 %), even at low concentrations, with the most efficient concentration being above the critical micelle concentration (CMC). Gemini surfactants also showed strong antimicrobial activity, with a minimum inhibitory concentration (0.018 mM). Corrosion inhibition was investigated by electrochemical impedance spectroscopy (EIS) and linear polarisation resistance (LPR), with biocorrosion experiments carried out in an anaerobic environment. Surface morphology was analysed using scanning electron microscopy (SEM).

“…They observed that the hydrophobicity of alkyl chains of m ‐E2‐ m molecules plays a crucial role in the steel protection. Kaczerewska et al investigated the effectiveness of O‐bridged cationic gemini surfactants ( n ‐O‐ n and n ‐MOH‐O‐MOH‐ n , n = 12, 18) for stainless steel protection in 3 M HCl.· Experimental and theoretical studies showed that the cationic gemini surfactants with longer alkyl chain possessed higher corrosion inhibition performance. These prominent works demonstrate that the corrosion inhibition efficiency also depends on the surfactant's alkyl chain length.…”

A new series of N‐alkyl‐N,N‐dimethyl‐N‐(3‐thienylmethylene)ammonium bromides (designated as NTA‐n, n = 8, 10, 12, 14, and 16) were synthesized. The electrochemical impedance spectroscopy (EIS) and potentiodynamic polarization showed that NTA‐n could protect availably X70 steel from attack of HCl with an inhibition efficiency of about 95%. And the inhibition ability follows the following sequence: NTA‐8 < NTA‐10 < NTA‐12 < NTA‐14 < NTA‐16, suggesting that prolonging alkyl chain may enhance the inhibition capacity of the molecules. Theoretical investigation backs up well the experiment results. The correlation of theoretical calculation with the experiment results illustrated clearly double logarithmic relations between the corrosion current and the computed quantum chemical parameters such as the highest occupied molecular orbital energy ( E HOMO), energy gap (ΔE), molecular volume ( ν), electronegativity ( χ), the total energy of iron crystal with the adsorbed inhibitor molecule ( E total), the interaction energy of Fe (1 0 0) surface and inhibitor molecules ( E inhibitor), while an equation resembling Hammet relation was existed between the corrosion currents and the fraction of electrons transfer (ΔN). These linear correlations suggest the relation of the inhibitor structure with its inhibition activity: long alkyl chain and electron donating groups in NTA‐n will enhance the corrosion efficiency.

“…In particular, cationic quaternary ammonium surfactants have been reported to play a significant role in preventing corrosion in iron and steel materials in acidic environments (9)(10)(11)(12). Therefore, there has been a growing number of studies on the synthesis of di-cationic surfactants containing more than one positive group and their use as corrosion inhibitors in the acidic medium (15)(16)(17)(18)(19)(20)(21).…”

In this study, three aromatic-structured di-cationic surfactants with different length carbon chains were synthesized and inhibition efficiencies against metal corrosion in 1.0 M HCl solution were investigated. Corrosion inhibition efficiencies of di-cationic surfactants that structurally illuminated by spectroscopic methods (FT-IR and NMR) were determined in acidic media by gravimetric method based on weight loss in metal coupons. Corrosion tests resulted in good inhibition efficiencies (90.40% - 96.85%) against metallic corrosion at different concentrations of inhibitors. By using the weight loss values, corrosion rates were also calculated in the inhibited and uninhibited medium. Finally, images of metal surfaces were obtained using scanning electron microscopy to support the obtained corrosion inhibition effect results.
