“…Xu et al prepared zeolitic imidazolate framework-8 (ZIF-8) in situ on the surface of Zn–Al LDHs and then loaded the corrosion inhibitor 1 H -benzotriazole (BTA) PVB/(LDH/ZIF-8@BTA). 123 LDH/ZIF-8@BTA were filled in the polyvinyl butyral (PVB) coatings to effectively enhance the passive and active anti-corrosion performance of the composite coatings for metal substrates. LDH-conductive polymer composites can also achieve synergistic anti-corrosion effects.…”

“…While pristine LDHs can provide corrosion-protective properties, their performance can be enhanced considerably by the addition of corrosion inhibitors and additives that can alter the diffusion pathway. As illustrated in Table 1, some of the lowest corrosion currents and/or highest resistance values are seen with added corrosion inhibitors [142], graphene [143] and metal organic frameworks (MOFs) [144]. In addition, LDHs can be combined with oxidized Al substrates, where the Al substrate is first oxidized through a plasma electrolytic oxidation (PEO) process [126,127].…”

Metals and alloys are essential in modern society, and are used in our daily activities. However, they are prone to corrosion, with the conversion of the metal/alloy to its more thermodynamically-favored oxide/hydroxide phase. These undesirable corrosion reactions can lead to the failure of metallic components. Consequently, corrosion-protective technologies are now more important than ever, as it is essential to reduce the waste of valuable resources. In this review, we consider the role of emerging 2D materials and layered materials in the development of a corrosion protection strategy. In particular, we focus on the materials beyond graphene, and consider the role of transition metal dichalcogenides, such as MoS2, MXenes, layered double hydroxides, hexagonal boron nitride and graphitic carbon nitride in the formulation of effective and protective films and coatings. Following a short introduction to the synthesis and exfoliation of the layered materials, their role in corrosion protection is described and discussed. Finally, we discuss the future applications of these 2D materials in corrosion protection.

“…34 The second method for corrosion inhibitor encapsulation is to grow a porous structure covering the layered materials and use their cavities as containers for capturing corrosion inhibitors. Metal−organic frameworks (MOFs), which were grown on graphene oxide 35,36 and LDHs, 37 were used for encapsulating corrosion inhibitors and then were hybridized with polymers. However, corrosion inhibitors were loaded or encapsulated in the containers by electrostatic interactions or were infiltrated into the pores of containers.…”

Two-dimensional materials have been introduced in polymer coatings to increase the lifetime of metallic materials by providing barrier properties against corrosive species. Corrosion inhibitors can be inserted into a 2D filler to mitigate the corrosion of metallic materials caused by corrosive species. Current drawbacks of this approach include a poorly controlled release of the inhibitor and the incompatibility of the filler and polymer. To achieve long-term anticorrosion performance, a layered silicate (octosilicate) is modified by surface-graft polymerization with a monomer functionalized with a corrosion inhibitor, 8hydroxyquinoline. A pH-responsive polymer-inhibitor conjugate, poly(methyl methacrylate-co-8-quinolinyl acrylate), is covalently attached to the silicate and then provides a sustainable release of the corrosion inhibitor upon acidification. The corrosion current density of aluminum alloy substrates (AA2024) coated with poly(methyl methacrylate-co-butyl acrylate) embedding the octosilicate containers is decreased due to a synergistic effect of barrier properties provided by the 2D filler and the pH-responsive release of corrosion inhibitor. This conceptual design can be potentially applied to release molecules such as drugs, fertilizers, or pesticides.
