“…They decreased until reaching the minimum values for F9 sample then start to increase in F10 and F11 coated steel. The shift of corrosion potential (E corr ) toward the positive direction for the samples coated with KPAn-loaded resins is due to the anodic protection of F8, F9, F10, and F11 samples [50]. This indicates the efficiency of PANI in KPAn to protect iron against corrosion by the formation of a passive layer on the surface of the MS [51].…”

Kaolinite/polyaniline nanocomposites (KPAns) were prepared by in situ chemical oxidative polymerization. The nanocomposites were synthesized with four different aniline to kaolinite weight percentage; 5, 10, 15, and 20% to produce KPAn5, KPAn10, KPAn15, and KPAn20, respectively. The structural, morphological and thermal properties of the nanocomposites were characterized using Fourier transform infrared, X‐ray diffraction, scanning electron microscope (SEM)–energy dispersive X‐ray analyzer, transmission electron microscope, and Thermogravimetric analysis. The results revealed a very slight increase in the d‐spacing of kaolinite XRD peaks. SEM images showed hexagonal platy sheets of kaolinite crystals that are indistinguishable in KPAn nanocomposites images, especially on using a high amount of polyaniline (PANI). The increase in the percentage of carbon and nitrogen elements in EDAX data proved the adsorption of PANI on the surface of kaolinite platelets. To investigate the anticorrosive performance of the synthesized nanocomposites, kaolinite and KPAn nanocomposites were loaded in various amounts (1, 5, and 9%) in a blend of chlorinated rubber/medium oil alkyd resin (CR/MA) to prepare different formulations that were applied and evaluated as protective coats on steel substrates. Visual corrosion test revealed that 5% KPAn‐loaded CR/MA coats exhibited the best protection against corrosion amongst other formulations as indicated by their lowest degree of rusting and blistering. Potentiodynamic polarization measurements confirmed the highest protection of 5% KPAn10‐loaded CR/MA coat as indicated by the quantitative corrosion rates obtained from Tafel extrapolation. POLYM.

The efficacy of Rumex Nervosus Vahl Leaves Ethanolic extract (RNVLE) to inhibit C38 steel corrosion in one molar hydrochloric acid medium was examined using electrochemical impedance spectroscopy (EIS) and potentiodynamic polarization. Polarization measurements revealed mixed-type inhibitor behavior. The inhibitory efficacy assessed by both polarization and (EIS) techniques was consistent, with an IE value of (96.0 %) and (95.5 %) at 2g/L of RNVLE, respectively. The RNVLE adsorption on the C38 metal surfaces in 1M HCl follows the Langmuir adsorption isotherm. The calculated free energy (G°ads equal to -16.1 KJ mol-1) explained that RNVLE controls the corrosion process by physisorption. The effect of immersion time was also investigated. This study demonstrated that RNVLE can be considered an excellent inhibitor up to 6 hours and after this time; it is considered a lower quality inhibitor although it still has sufficient inhibitory ability. SEM-EDX (Scanning Electron Microscopy and X-ray Energy Dispersive Spectroscopy) analysis revealed that the extract molecules adsorb on the metal's surface. These findings indicate that RNVLE can be used as an effective corrosion inhibitor for C38 steel in 1M HCl solution.
