Magnesium-based engineering materials are increasingly considered for transport applications due to their exceptional strength to weight ratios. [1] However, effective corrosion protection strategies are required due to the high chemical reactivity of magnesium (Mg). A promising approach to achieve the desired active corrosion protection are layered double hydroxides (LDHs) and that can act as nanocontainers for corrosion inhibitors. [2, 3] The key step for the active corrosion protection is the release of the intercalated inhibitors from the LDHs nanocontainers and the simultaneous uptake of aggressive anions (e.g. chloride, which initiate corrosion of Mg-based materials) through an anion-exchange mechanism. [2, 4].
