Polymer-Based Coating for Steel Protection, Highlighting Metal–Organic Framework as Functional Actives: A Review

Abstract: Polymer-based coatings are a long-established category of protective coatings for metals and alloys regarding corrosion inhibition. The polymer films can degrade, and when coated on metallic substrates, the degradation facilitates moisture and oxygen penetration, reducing the polymer film’s adhesion to the metallic substrate and exposing the substrate to extreme conditions capable of corrosion. For this reason, pigments, inhibitors, and other compatible blends are added to the polymer coating formulations to e… Show more

“…Polyurethane, polyimides, and silicone polymer coatings provide good protection at low cost (Brady, 1999; Guo et al, 2018; Ramezanzadeh et al, 2015). However, microbes can degrade the polymer coatings, reducing polymer adhesion (Ulaeto et al, 2023). The effectiveness of polymer coatings in preventing microbial corrosion can be improved with the incorporation of copper or silver to release toxic metal ions as the polymer is degraded, but this approach suffers from the limitations of toxic metal ions discussed above (Little et al, 2020).…”

“…First, the barrier mechanism of thin films is made up of a mixture of PAO, polyisobutylene and AL stearate to prevent corrosive agents from penetrating and impacting metal surfaces. Next, the nanofluid effect helps the DF(MgO-20) penetrate deeply into the crevices and pores on the metal substrates, which helps to remove the water layer on the metal surfaces [31]. This effect facilitates the anti-corrosion additives for ferrous metals (barium sulfonate) and non-ferrous metals (benzotriazol) to come into good contact with the metal substrate in order to create a polar covalent bond and adsorption of anti-corrosion additives on metal [32,33].…”

“…Corrosion is a major issue in most industrial fields, and there continues to be extensive research into functional coatings that can minimize its effects. Coatings containing nitrogen, sulfur, and oxygen functionalities have been reported to be inhibitors, with those possessing unsaturated bond networks exhibiting higher efficiency [97]. More recently, attention has turned to the use of conducting polymers, wherein there is extensive delocalization of pi electrons.…”
