摘要	The adsorption of infiltrated chloride ions by layered double hydroxide (LDH) is expected to improve the corrosion resistance of organic coatings. Mg/Al layered double hydroxide (LDH) with a Mg/Al molar ratio of 4:1 was prepared using the co-precipitation method. The calcined layered double hydroxide (CLDH) was placed in NaCl solution to investigate its effect upon the adsorption of Cl-, then, the product was added to a two-component epoxy coating, to study its effect upon corrosion resistance. The CLDH powder product was characterized using XRD and FT-IR, and the corrosion resistance of the coatings was investigated by EIS and NSS tests. The experimental results show that CLDH can effectively adsorb Cl- from a NaCl solution via its memory effect, and the corrosion resistance of the epoxy coating can be improved by adding 1.0-2.0 wt. % CLDH.
