“…As the results of acid solution used in pickling, cleaning, and descaling may lead to corrosion of steel 5–7 . Therefore, from this standpoint, the researchers in this field have tended to use inhibitors as one of the most effective ways to protect metals from corrosion in various acidic media 8–10 . Organic compounds containing heteroatoms such as (N, O, and S), as well as, Л‐ electrons in their molecular structure are considered effective corrosion inhibitor, which can form a protective layer on the metal surface that prevents corrosion 11–15 .…”

In the present work, the Curam drug was used as an eco-friendly corrosion inhibitor for the protection of stainless steel 304 (SS-304) in 2.0 M HCl solution. The inhibition efficiency was determined by mass loss (ML), Potentiodynamic polarization (PDP), and electrochemical impedance spectroscopy (EIS) measurements. The surface morphology analysis carried out using Fourier transform infrared spectroscopy (FT-IR) and atomic force microscopy (AFM). ML data prove that with an increase in the temperature, Curam still exhibits good anti-corrosion performance. The inhibition efficiency of Curam can still be maintained at about 72% at 318 K. The data of electrochemical measurements indicate that Curam is the mixed-type inhibitor. The adsorption process of Curam on the SS-304 surface obeys the Langmuir adsorption isotherm. FT-IR and AFM analysis showed the excellent inhibition performance of Curam for SS-304 dissolution in an acidic medium. The data obtained by chemical and electrochemical measurements are in good agreement with one another.

“…There is a significant interest in the development of high-performance anticorrosive coatings that are capable of combining the properties of the nanostructure and the polymeric matrix. Such composite systems based on graphene oxide have been studied and they include polymers such as benzoxazine, polyaniline, polyurea, polyurethane, and epoxy resin, which is the most used and effective polymeric material in the coatings industry [78][79][80][81][82]. Polymeric materials tend to form a high adhesive barrier due to the fact that they can chemically interact by covalent bonding to different substrates.…”

The present review outlines the most recent advance in the field of anticorrosive coatings based on graphene oxide nanostructures as active filler. This carbonaceous material was extensively used in the last few years due to its remarkable assets and proved to have a significant contribution to composite materials. Concerning the graphene-based coatings, the synthesis methods, protective function, anticorrosion mechanism, feasible problems, and some methods to improve the overall properties were highlighted. Regarding the contribution of the nanostructure used to improve the capability of the material, several modification strategies for graphene oxide along with the synergistic effect exhibited when functionalized with other compounds were mainly discussed.

“…15 Research activities have focused on the synthesis and distinctive applications of aniline oligomer-based polymers. Yeh et al reported that electroactive epoxy thermoset (EET) coatings with an amine-capped aniline trimer (ACAT) in the main chain 16 or AP in the side chain 17 exhibit significantly enhanced anticorrosion performance for cold-rolled steel (CRS) electrodes as compared to neat non-electroactive epoxy coatings. The EET has enhanced corrosion resistance due to the electrocatalytic ability of aniline oligomers to form a densely passivated metal oxide layer on the CRS electrode to protect the underlying metal substrate, which was consistent with the results with PANI reported by Wessling.…”

Zinc-rich epoxy coating plays a major role in current heavy-duty corrosion protection solutions, yet high loading of zinc dust (ZD) weakens the coating flexibility and adhesion capability of the overall coating. This work demonstrated the successful incorporation of small amounts of rGO and aniline pentamer (AP)-based diamine into zinc-rich non-electroactive epoxy thermoset (NEET) as a novel heavy-duty anticorrosion coating composite. This coating composite promoted its wear resistance without sacrificing anticorrosion performance and adhesion ability while effectively reducing the loading of ZD. Based on a series of electrochemical measurements, an electroactive epoxy thermoset (EET) containing 5 wt % electroactive APbased diamine (DAAP) and 0.5 wt % rGO can replace 70 wt % ZD and shows equivalent anticorrosion performance under an accelerated salt-spray assay and electrochemical corrosion measurements. Furthermore, coatings containing DAAP and rGO exhibited improved wear resistance and good adhesion capability.
