“…The charged inhibitors can be easily chelated with the positively charged steel surfaces to obtain promising protection. For instance, in some recent works, Sodium lignosulfonate [38], Polycarboxylates [39], Alcamines [40], Quaternium-32 [31], and Carboxylate derivatives [30] were applied to protect the steel from corrosion against concrete pore solution attacks. All studies tried to survey the mentioned inhibitors' performance via different electrochemical and morphological methods and they claimed reliable results.…”

Corrosion has caused significant annual costs for building construction and civil architectural designs. In this study, Monosodium glutamate (GLU) was proposed as a potential candidate for long-lasting corrosion inhibition to slow down the rate of corrosion in the concrete pore environment. In this regard, the electrochemical and morphological properties of the various GLU concentrated systems between 1 to 5 wt.% in the simulated concrete pore solution media were investigated. According to the EIS results, adding 4 wt.% of GLU could reduce the mild steel corrosion process by 86% through a mixed inhibition mechanism. Also, the polarization records represented that the samples' corrosion current density was diminished to 0.169 µA.cm-2 after the addition of 4 wt.% GLU into the harsh environment. Using the FE-SEM method, the growth of the GLU layer over the metal substrate was demonstrated. The results of spectroscopic methods, i.e., Raman and GIXRD, demonstrated that GLU molecules were successfully adsorbed over the surface of the metal. Contact angle test outcomes showed that by increasing the GLU concentration to its optimum level (4 wt.%), the surface hydrophobicity was dramatically raised to 62 degrees.

“…Equipment operating in such conditions is susceptible to metal corrosion, resulting in environmental pollution, economic losses, and potential safety hazards. To address the issues caused by corrosion damage, various approaches have been proposed, including the addition of corrosion inhibitors to concrete [5][6][7], the use of electrochemical protection methods [8], and the application of metal coating techniques [9,10]. The application of protective coatings stands out as an economically viable and effective anti-corrosion strategy.…”

Polyaniline (PANI) doped with hydrochloric acid and phytic acid are prepared as benzotriazole (BTA) inhibitor carriers, and their anticorrosion properties are studied on epoxy resin-coated Q235 steel. The structure and morphology of the prepared PANI materials are investigated by Fourier transform infrared spectroscopy (FTIR), X-ray diffraction (XRD) and scanning electron microscopy (SEM). The thermal stability of PANI and its release rate of corrosion inhibitor are measured, and the test results indicate that hydrochloric acid-doped PANI can accommodate a larger amount of corrosion inhibitor. The results of contact angle and water absorption tests show that the PANI loaded with BTA can improve the hydrophobicity and reduce the water absorption of the coating. The anticorrosion performances of epoxy coatings with 0.6 wt% PANI are investigated in 3.5 wt% NaCl solution using electrochemical tests. The experimental results reveal that PANI loaded with BTA shows a good anticorrosion effect in the epoxy coating. Particularly, phytic acid-doped PANI loaded with BTA has a better inhibition efficiency (93.6%), which is superior to hydrochloric acid-doped PANI loaded with BTA (86.4%).
