文摘

Zn-Al- layered double hydroxides were successfully doped with phosphate ions. Phosphate loaded nanocontainers showed better inhibition effect than nitrate one and formed passive film on steel surface. Silane film including Zn-Al-PO43− nanocontainer significantly reduced cathodic delamination of epoxy coating on steel. The improvement of self-healing ability of the coatings loaded with Zn-Al-PO43− was much higher than Zn-Al-NO3−.
