Corrosion inhibiting pigment comprising nanoreservoirs of corrosion inhibitor

摘要

The invention provides a corrosion inhibiting pigment comprising nanoscale reservoirs (nanoreservoirs) of corrosion inhibitor for active corrosion protection of metallic products and structures, wherein the nanoreservoirs comprise a polymer or polyelectrolyte shell which is sensitive to a specific trigger and capable to release said inhibitor after action of said trigger. Also provided by the present invention are an anti-corrosive coating with self-healing properties comprising said pigment, methods for preparing said pigment, in particular by layer-by-layer deposition, as well as methods of use of said pigment.
