摘要:
A corrosion inhibiting pigment includes nanoscale reservoirs (nanoreservoirs) of corrosion inhibitor for active corrosion protection of metallic products and structures, wherein the nanoreservoirs include a polymer or polyelectrolyte shell which is sensitive to a specific trigger and capable of releasing the inhibitor after action of the trigger. An anti-corrosive coating with self-healing properties includes the pigment, methods for preparing the pigment, in particular by layer-by-layer deposition, as well as methods of use of the pigment.
