“…The structural groups for the repeating units of several polymer corrosion inhibitors are summarized in Figure 13. [225,226]. Unexpectedly, through stationary and transiency measurements, the inhibition efficiency of this new epoxy resin reached a value of 92% at only a concentration of 1 mM, and it was also observed that C38 steel surface morphology in the presence of inhibitor remained clean after immersion in 1.0 M HCl, which shows that this epoxy resin protected the C38 steel well against corrosion.…”

“…Structural groups of polymer inhibitors.Epoxy resin is defined as low-molecular-weight pre-polymers with two or more epoxy groups, which is the most common polymeric coating, but there are also examples of studies that investigate the possible use of epoxy resin as corrosion inhibitor for carbon steel in 1.0 M HCl media. In a recent study, Damej et al synthesized a new organic compound type epoxy resin, namely N, N, 1-tri(oxiran-2-ylmethoxy)-5-((oxiran-2ylmethoxy)thio)-1H-1,2,4-triazol-3-amine used as corrosion inhibitor for carbon steel C38 in 1.0 M HCl[225,226]. Unexpectedly, through stationary and transiency measurements, the inhibition efficiency of this new epoxy resin reached a value of 92% at only a concentration of 1 mM, and it was also observed that C38 steel surface morphology in the presence of inhibitor remained clean after immersion in 1.0 M HCl, which shows that this epoxy resin protected the C38 steel well against corrosion.Polyaniline and its derivatives are effective corrosion inhibitors of mild steel in acidic media, which have been well known for years by industry experts.…”

Most studies on the corrosion inhibition performance of organic molecules and (nano)materials were conducted within “carbon steel/1.0 M HCl” solution system using similar experimental and theoretical methods. As such, the numerous research findings in this system are sufficient to conduct comparative studies to select the best-suited inhibitor type that generally refers to a type of inhibitor with low concentration/high inhibition efficiency, nontoxic properties, and a simple and cost-economic synthesis process. Before data collection, to help readers have a clear understanding of some crucial elements for the evaluation of corrosion inhibition performance, we introduced the mainstay of corrosion inhibitors studies involved, including the corrosion and inhibition mechanism of carbon steel/HCl solution systems, evaluation methods of corrosion inhibition efficiency, adsorption isotherm models, adsorption thermodynamic parameters QC calculations, MD/MC simulations, and the main characterization techniques used. In the classification and statistical analysis section, organic compounds or (nano)materials as corrosion inhibitors were classified into six types according to their molecular structural characteristics, molecular size, and compound source, including drug molecules, ionic liquids, surfactants, plant extracts, polymers, and polymeric nanoparticles. We outlined the important conclusions obtained from recent literature and listed the evaluation methods, characterization techniques, and contrastable experimental data of these types of inhibitors when used for carbon steel corrosion in 1.0 M HCl solution. Finally, statistical analysis was only performed based on these data from carbon steel/1.0 M HCl solution system, from which some conclusions can contribute to reducing the workload of the acquisition of useful information and provide some reference directions for the development of new corrosion inhibitors.

“…According to the data displayed in Table 1 , careful analysis of the anodic and cathodic Tafel slopes suggests that, with the addition of the TGP prepolymer, both slopes were changed compared to the 1 M HCl solution alone [ 32 ]. Additionally, the reaction mechanisms, both anodic and cathodic, for the unprotected and protected by different concentrations of the epoxy prepolymer were confirmed to be constant as the shape of the polarization curves remained the same, showingthat the epoxy prepolymer synthesized adsorbed on the metallic area through blocking the active centers [ 6 , 20 ].…”

“…The introduction of organic inhibitors such as quinoxaline, quinoline, polymer composites and epoxy prepolymers has become one of the most effective approaches for retarding the corrosion of mild steel in different aggressive solutions [ 3 , 4 , 5 ]. Multifunctional epoxy prepolymer molecules possessing oxygen, sulfur and nitrogen heteroatoms and electronegative polar groups, as well as aldehydes, carboxyl, amino, oxirane groups have been used to display excellent protective abilities ascorrosion inhibitors by forming a chemical bond with the metallic surface [ 6 , 7 , 8 , 9 ]. Epoxy prepolymer molecules have π-electrons and unsaturated donating and are able to accept electrons in their low-energy empty orbitals [ 10 , 11 ].…”

“…The presence of an oxirane group, carbonyl compounds and oxygen heteroatoms enables it to cooperate with an iron surface, facilitating the adsorption of epoxy prepolymer on the metallic area and acting as a corrosion inhibitor [ 18 , 19 , 20 , 21 ]. Damej et al studied N,N-1-tri(oxiran-2-ylmethoxy)-5-((oxiran-2-ylmethoxy)thio)-1H-1,2,4-triazole-3-amine as a potential corrosion inhibitor for steel in 1 M HCl solution and found ahigh inhibitory efficiency of 92% at lower concentration (1mM) [ 6 ].…”

Synthesis Characterization and Highly Protective Efficiency of Tetraglycidyloxy Pentanal Epoxy Prepolymer as a Potential Corrosion Inhibitor for Mild Steel in 1 M HCl Medium

et al. 2022

View full text Add to dashboard Cite

Anticorrosive protection efficiency of novel tetrafunctional epoxy prepolymer, namely 2,3,4,5-tetraglycidyloxy pentanal (TGP), for mild steel in 1 M HCl medium was assessed through potentiodynamic polarization (PDP), electrochemical impedance spectroscopy (EIS), scanning electron microscope (SEM), energy dispersive X-ray spectroscopy (EDS), contact angle (CA), adsorption isotherm model, temperature effect and thermodynamic parameters. The synthesized TGP was characterized and confirmed by Fourier transform infrared (FTIR) spectroscopy and nuclear magnetic resonance (NMR). The inhibitory efficiencies found at lower concentration of the prepolymer TGP were85% (PDP) and 87.17% (EIS). PDP measurement illustrated that the TGP behaved as a mixed-type inhibitor in the realized solution. SEM and EDS analysis showeda significant decrease in the corrosion of the MS surface in the presence of the inhibitory prepolymer compared with the blank (1 M HCl). Langmuir adsorption isotherm is the most acceptable modelto describe the TGP epoxy prepolymer on the MS area.

N-CDs, as a novel and eco-friendly inhibitor, were synthesized easily by hydrothermal carbonization technique aiming to inhibit mild steel corrosion in 1 mol. L − 1 HCl. XRD, TEM, SEM, FTIR, UV-vis spectrophotometer and photoluminescence (PL) were utilized to characterize N-CDs. Potentiodynamic polarization and electrochemical impedance spectroscopy techniques along with the complementary surface studies were combined to investigate the corrosion inhibition capability of N-CDs for MS. N-CDs were found nanometer-sized (≈ 4 nm) with quasi-spherical morphology and high crystallinity. Inhibition e ciency, directly proportional to concentration but inversely with temperature, was measured as high as 96.73% (PDP) and 95.21% (EIS) at 200 mg. L − 1 . Inhibition mechanism refered mainly to adsorption process that good obeyed Langmuir adsorption isotherm. The surface studies, quantitatively veri ed by EDX, showed a smoother surface of MS in presence of the N-CDs. Furthermore, the UV-visible spectroscopy effectively revealed the complexations between iron and metal surfaces. IntroductionRecently, designing materials at nanoscale has acquired fundamental applications in many elds starting from everyday life to space innovation. Materials at the nanoscale have extraordinary physical, chemical, electrochemical, mechanical, thermal and biological properties due to their nanoscale size, surface and quantum impacts, that allow to manufacture stronger, harder, biocompatible, and highly corrosion-resistant materials with a wide range of applications in biomedicine, diagnosis, electronics, agriculture, food, pharmaceuticals, energy harvesting for self-powered nano systems, chip fabrication, batteries, fuel cells, corrosion protection of materials, aerospace materials, cosmetics, etc. [1] Among nanomaterials are carbon dots (C-Dots) which plays an important role in nanoscience and nanotechnology since its discovery in 2004 due to their exceptional properties like high uorescencence, water solubility and biocompatibility, low toxicity, and extra small sizes in the range 1-10 nm [2-4]. The subsequent extensive studies gradually revealed the potential applications of C-Dots including anti-counterfeiting [5], optoelectronics [6], uorescence imaging both in vitro & in vivo [7-9], solar cells [10], nanosensing both in vitro & in vivo [8, 11-13], light-emitting devices [14], photocatalysis [11], drug delivery [15], diagnosis of diseases [16], etc. Since 2017, the carbonization of either synthetic and natural organic compounds give rise to the carbon nanodots that revolutionized the eld of metals corrosion inhibition [17-21]. Next work deals with synthesis of C-Dots by the traditional, eco-friendly hydrothermal carbonization method. The properties exhibited by C-Dots depend on the C-sources and conditions used in the synthesis.Most industrial equipment like engineering vehicles, reaction vessels and packaging machineries made from metallic products are inclined to corrosion. One of the most e cient ways of relieving corrosion process is usin...
