Abstract
Nanocomposite anticorrosion coating can be achieved by depositing alternating, multilayers of a cross-linkable polymer and dispersed and aligned inorganic platelets followed by cross-linking of the cross-linkable polymer. The cross-linkable polymer can be an externally cross-linkable polymer that is cross-linked by diffusing a cross-linking agent into the deposited multilayer coating. Alternately, the cross-linkable polymer can be a functionalized cross-linkable polymer that is cross-linked by self-curing, thermal heat curing, or light (e.g., UV) following deposition of the multilayer coating.
Claims9
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.
