Abstract: Layered double hydroxide (LDH) has been widely studied by researchers due to their corrosion inhibitor container function, anion-exchange effect, and two-dimensional layered structure, which has great potential for application in anti-corrosion coatings. LDH can absorb chloride ions and release corrosion inhibitor ions through anion-exchange effect, reducing the attacking intensity of chloride ions on the substrate while releasing corrosion inhibitors to repair the corroded area, and make the system have a self-healing effect. However, LDH is prone to form aggregates in coatings and has poor compatibility with coatings, which limits its multifunctional properties in coatings. In this study, the work carried out by researchers in improving the compatibility between LDH and coatings is summarized, and the outlooks in this field is put forward.
