1. A method for depositing a nanocomposite anticorrosion coating on a corrodible metal, comprising
depositing at least one bilayer on a surface of the corrodible metal, the bilayer comprising a layer of a functionalized cross-linkable polymer and a layer of dispersed and aligned platelet particles, wherein the functionalized cross-linkable polymer comprises a polymeric amine that is partially reacted with an epoxy resin to a specified conversion state; and
cross-linking the functionalized cross-linkable polymer by self-curing, thermal heat curing, or light curing subsequent to depositing the at least one bilayer.
