“…This indicates that a chemical reaction occurred after treating the filler with EP, resulting in the chemical bond breaking. In addition, the stretching vibration of the epoxy ring located at 912 cm −1 did not appear in the spectra of CeO 2 -F/EP, implying that epoxy ring was involved in the chemical reaction and the unreacted E-44 has been eliminated (Dong et al , 2023). Based on the above discussion, E-44 has undergone a chemical ring opening reaction with CeO 2 -f.…”

Purpose The study aims to investigate the anticorrosion performance of epoxy coatings using modified cerium oxide (CeO2) by terephthalic acid (CeO2-t) and fumaric acid (CeO2-f) as corrosion inhibitors. Design/methodology/approach The chemical state of CeO2-t, and CeO2-f were analyzed by infrared radiation (IR) and X-ray diffraction (XRD). The effect of different inhibitors on the coating properties was analyzed by neutral salt spray tests (NSST) and electrochemical impedance spectroscopy (EIS). Findings The results of IR and XRD illustrate that the modification of CeO2 was successful, and fumaric acid underwent a ring-opening reaction with epoxy resin (EP) in the coatings. The results of NSST and EIS showed that the coatings containing CeO2-f exhibited the best anticorrosion performance. Originality/value CeO2 is an effective inhibitor of the organic coatings. When surface modified, it is chemically bonded to EP, enhancing the anticorrosion performance of EP.

“…CeO 2 and cerium salts are effective metal corrosion inhibitors and are frequently used by researchers to modify PANI fillers (Dong et al, 2023a;Dong et al, 2023b;Tavandashti et al, 2016a). The protection of PANI/CeO 2 epoxy coatings was accessed by Lei et al (2020), and results from LEIS have demonstrated the exceptional improvement of corrosion protection performance provided by the PANI/ CeO 2 /epoxy coatings.…”

Purpose Polyaniline (PANI) has garnered attention for its potential applications in anticorrosion fields because of its unique properties. Satisfactory outcomes have been achieved when using PANI as a functional filler in organic coatings. More recently, research has extensively explored PANI-based organic coatings with self-healing properties. The purpose of this paper is to provide a summary of the active agents, methods and mechanisms involved in the self-healing of organic coatings. Design/methodology/approach This study uses specific doped acids and metal corrosion inhibitors as active and self-healing agents to modify PANI using the methods of oxidation polymerization, template synthesis, nanosheet carrier and nanocontainer loading methods. The anticorrosion performance of the coatings is evaluated using EIS, LEIS and salt spray tests. Findings Specific doped acids and metal corrosion inhibitors are used as active agents to modify PANI and confer self-healing properties to the coatings. The coatings’ active protection mechanism encompasses PANI’s own passivation ability, the adsorption of active agents and the creation of insoluble compounds or complexes. Originality/value This paper summarizes the active agents used to modify PANI, the procedures used for modification and the self-healing mechanism of the composite coatings. It also proposes future directions for developing PANI organic coatings with self-healing capabilities. The summaries and proposals presented may facilitate large-scale production of the PANI organic coatings, which exhibit outstanding anticorrosion competence and self-healing properties.

“…For the first approach, various organic and inorganic inhibitors were added into the epoxy coating formulations (De Lima-Neto et al , 2008; Morozov et al , 2019; Toorani et al , 2021; Sanaei et al , 2017; Bahrani et al , 2018; Xavier, 2018; Nguyen et al , 2022b; Dong et al , 2023a; Dong et al , 2023b). These inhibitors were added into coating ingredients through various coating layers, such as pretreatment/primer coat/topcoat.…”

Purpose This study aims to explore the synergistic effect of oxide nanoparticles (ZnO, Fe2O3, SiO2) and cerium nitrate inhibitor on anti-corrosion performance of epoxy coating. First, cerium nitrate inhibitors are absorbed on the surface of various oxide nanoparticles. Thereafter, epoxy nanocomposite coatings have been fabricated on carbon steel substrate using these oxide@Ce nanoparticles as both nano-fillers and nano-inhibitors. Design/methodology/approach To evaluate the impact of oxides@Ce nanoparticles on mechanical properties of epoxy coating, the abrasion resistance and impact resistance of epoxy coatings have been examined. To study the impact of oxides@Ce nanoparticles on anti-corrosion performance of epoxy coating for steel, the electrochemical impedance spectroscopy has been carried out in 3% NaCl solution. Findings ZnO@Ce3+ and SiO2@Ce3+ nanoparticles provide more enhancement in the epoxy pore network than modification of the epoxy/steel interface. Whereas, Fe2O3@Ce3+ nanoparticles have more to do with modification of the epoxy/steel interface than to change the epoxy pore network. Originality/value Incorporation of both oxide nanoparticles and inorganic inhibitor into the epoxy resin is a promising approach for enhancing the anti-corrosion performance of carbon steel.
