Inhibition effect of monomeric/polymerized imidazole zwitterions as corrosion inhibitors for carbon steel in acid medium

Engineering a self-adaptive electric double layer on both electrodes for high-performance zinc metal batteries

“…5d, the Raman peaks at 1022 cm −1 arise from the vibration of the π–π conjugation imidazolium ring from the ImS additive, and its concentration at the interface rises gradually with the increase of deposition time, indicating the enrichment of the ImS under the electric field. 69,70 Similarly, the concentration of –SO 3 − from ImS also increased with the deposition time. In particular, the concentration of sulfate also slightly increases, while theoretically, the content of SO 4 2− at the interface should decrease due to the repulsion of the EDL.…”

“…The ImS additive with a p-p conjugation imidazolium cation provides a positively charged electrostatic layer, which leads to an even distribution of the Zn 2+ on the interface, and thus the uniform current density distribution. 70,74 Based on the simulated electric fields, the ion diffusion situation was further emulated to represent the distribution of the Zn 2+ concentration field as deposition progresses. At the transitional stage of plating, a large number of Zn 2+ ions rapidly gathered at the tips of the protrusions in the pure ZSO electrolyte, but the adjacent domains and bottom of the protrusion exhibited low Zn 2+ concentration.…”

Exploration of Sunflower Oil As a Renewable Biomass Source to Develop Scalable and Highly Effective Corrosion Inhibitors in a 15% HCl Medium at High Temperatures

“…The inhibition efficiency of the SFOCIs was calculated by using eq : where i corr ° and i corr I are, respectively, corrosion current densities without and with different concentrations of SFOCIs. In addition, the Stern–Geary eq was employed to calculate the polarization resistance ( R p ): One of the obvious results from Figures and Figure S2 is that the addition of SFOCIs to the acidic environment caused a change in the anodic and cathodic current densities especially at high temperatures as a result of the reduction of the anodic and cathodic corrosion reactions by a mixed inhibition mechanism …”

“…In addition, the Stern−Geary eq 3 was employed to calculate the polarization resistance (R p ): One of the obvious results from Figures 3 and Figure S2 is that the addition of SFOCIs to the acidic environment caused a change in the anodic and cathodic current densities especially at high temperatures as a result of the reduction of the anodic and cathodic corrosion reactions by a mixed inhibition mechanism. 50 Table 2 and Table S1 demonstrate that the presence of SFOCI 400 and 1000 in the 15% HCl solution affected the Tafel slopes values. Figure 3 and Table S2 also show that both anodic and cathodic slopes of Tafel were altered in the solution containing SFOCIs.…”

Temperature Effect on the Corrosion Inhibition of Carbon Steel by Polymeric Ionic Liquids in Acid Medium

“…Notwithstanding, despite the aforementioned properties, their application as CIs has not been studied enough. Wang et al [ 19 ] and Odewunmi et al [ 20 ] carried out an interesting comparison between the structure of ILs and their corresponding polymeric forms as PILs to be potentially used as CIs of steel in HCl and found that PILs displayed a better inhibiting effect than their related IL species alone due to a higher number of functional groups in their structure. Additionally, Odewunmi et al stated that PILs with halide anions provide an excess of electrons that allows for the attraction and adsorption of the polymeric cationic species.…”
