“…In contrast, quite sharp declines could be noticed, after 10 days, through applying 200 ppm as an inhibitor dose. This sharp drop could be attributed to the exhaustion of a quite increased number of the inhibitor particles by time passing (Al-Bghdadi et al 2019). Hence, the remained non-exhausted particles could not potentially provide efficient coverage to the steel surface.…”

Corrosion is one of the serious problems countered in different industries as it dramatically causes strong impacting on the infrastructures. As an attempt for sorting out such problem, this approach investigated an innovative strategy for synthesis of corrosion inhibitor for steel surfaces based on composite of polystyrene and zinc nanoparticles (ZnNPs@polystyrene composite). The successive immobilization of ZnNPs (size average of 4-50 nm) within polystyrene matrix (Mwt of 372.587 g/ mole and degree of polymerization equals 3582 repeat unit/ molecule) for clustering of the desirable ZnNPs@polystyrene composite (surface area of 33.62 m2/g, average pore diameter of 9 nm) was approved via several instrumental analyses of FT-IR, XRD, SEM, HRSEM, EDX, TEM and BET with estimation of total pore volume and average pore diameter for the prepared composite. Thermal stability of the prepared composite was affirmed via TGA analysis. Corrosion percentage via weight loss percent in three media of water, H2SO4 and diesel fuel was estimated to reach maximally to 25 % in case of H2SO4, while, corrosion inhibition efficiency (CIE) percentage estimated according to weight loss to reach 94.27, 88.18 and 85.05 % after 10 days of soaking the steel samples coated with the synthesized ZnNPs@polystyrene composite (800 ppm) at 25 ℃, while, elevation of temperature up to 45 ℃, resulted in non-significant effect on the estimated CIE to be diminished to 91.8, 85.2 and 81.1% after soaking in water, diesel fuel and sulfuric acid as corrosion media, respectively. CIE was estimated to be near 30% in case of coating steel samples with polystyrene polymer, to be significantly increased to near 80 % and formidably jumped to near 100% by coating with ZnNPs@polystyrene composite, with weight percent of 30 & 50% of ZnNPs, respectively. In addition to, Zeta potential was also detected to be - 9.67 in case of untreated steel samples, while, it became - 4.98 after coating of sample with ZnNPs@polystyrene composite. Eventually, from Arrhenius plots, activation energies and thermodynamic parameters of rate constant, enthalpy (ΔH) and entropy (ΔS) confirmed that the interaction is more taking place between the corrosion species and ZnNPs@polystyrene composite as corrosion inhibitor rather than with steel surface. Postulation of the reaction mechanism for the anticorrosive action of the synthesized ZnNPs@polystyrene composite was presented according to the illustrated instrumental analyses.

“…While inorganic inhibitors like chromates and phosphates have seen widespread use across industries, [19,20] mounting concerns regarding toxicity and environmental impacts have spurred increased interest in the development of organic alternatives. [21][22][23] Organic compounds enriched with nitrogen, sulfur, and oxygen atoms have garnered attention for their remarkable inhibitory capabilities, rooted in their capacity to form protective layers on metal surfaces. [24,25] The effectiveness of organic inhibitors hinges on a multitude of factors, including their chemical makeup, adsorption behavior, and electrochemical characteristics, leading to classifications such as azoles, imidazoles, quinolines, and amines based on their structural features.…”

The corrosion of mild steel in HCl solution remains a critical issue in various industrial applications. In the quest for effective corrosion inhibitors, 4‐(2‐Hydroxy‐3‐Methoxybenzylideneamino) antipyrine (HMBA) has emerged as a promising candidate. This study investigates the inhibitory properties of HMBA on mild steel corrosion in HCl solution through weight loss measurements, electrochemical impedance spectroscopy (EIS), and potentiodynamic polarization (PDP) techniques. The experiments spanned over various time periods, including 1, 5, 10, 24, and 48 h. The results reveal that HMBA exhibits exceptional inhibition efficiency (IE), with an impressive 94.7% inhibition rate. This outstanding performance underscores its potential as a corrosion inhibitor for mild steel in aggressive HCl environments. To elucidate the adsorption behavior of HMBA on the mild steel surface, Langmuir isotherm modeling was employed, demonstrating a strong correlation between the experimental data and the Langmuir adsorption isotherm model. Furthermore, the study employs density functional theory (DFT) to gain insight into the mechanism of HMBA inhibition. DFT calculations suggest that both physisorption and chemisorption mechanisms are involved in the interaction between HMBA and the mild steel surface. The calculated Gibbs free energy of adsorption () is found to be approximately , indicating a spontaneous and energetically favorable adsorption process. In conclusion, HMBA emerges as a highly effective corrosion inhibitor for mild steel in HCl solution, offering impressive IE over various time intervals. The combination of experimental techniques, such as WL, EIS, and PDP, along with computational insights from DFT calculations, provides an understanding of the inhibitory properties of HMBA. These findings hold great promise for the development of environmentally friendly corrosion inhibitors in industrial applications.
