“…In the HT case, there is a broad absorption peak around 3480 cm −1 , ascribing to the stretching vibration of OH; as well as that in the PA‐HT case. The peaks at 500–700 cm −1 are ascribed to the MO, MOM and OMO bonds 38 . In HT case, the peak at 1366 cm −1 is ascribed to the vibration of NO 3− in the lamellar spacing of HT.…”

“…The peaks at 500-700 cm À1 are ascribed to the M O, M O M and O M O bonds. 38 In HT case, the peak at 1366 cm À1 is ascribed to the vibration of NO 3À in the lamellar spacing of HT. In PA-HT case, the characteristic peak of NO 3À disappeared and the peak at 1038 cm À1 appeared ascribing to the P O bond, which demonstrates that PA has been successfully interlaminated into HT fillers.…”

Epoxy resin has been widely applied in coating preparation, due to its excellent properties. The anti‐corrosion performance improvement of epoxy‐based coatings has attracted much attention. The synergistic effect of the barrier function of two‐dimensional fillers and the slow release of inhibiter has been proven to be an effective way to improve the anti‐corrosion of coatings. In this work, the phytic acid (PA) intercalated hydrotalcite (HT) was fabricated by a one‐pot method. First, HT was synthesized by magnesium nitrate hexahydrate (Mg(NO3)2·6H2O) and aluminum nitrate nonahydrate (Al(NO3)3·9H2O) in the water solution. Subsequently, PA was added to the dispersion to obtain PA intercalated HT fillers (PA‐HT). The obtained PA‐HT fillers were incorporated into the epoxy resin (EP) to prepare the anti‐corrosion coating (PA‐HT/EP). The prepared PA‐HT/EP coating exhibits excellent anti‐corrosion properties at 1 wt% filler loading that the impedance modulus maintains above 109 Ω cm2 after 30 days of soaking in 3.5 wt% NaCl solution. Moreover, the anti‐corrosion mechanism of the synergy of the physical barrier of two‐dimensional fillers and the release slow of inhibitors was thoroughly discussed, particularly the formation and anti‐corrosion mechanism of the passivation protection film constituted by PA.
