Abstract
The present invention includes compositions and methods of supplying a corrosion inhibitor including placing a corrosion inhibitor attached to a nanostructure carrier, placing the nanostructure carrier containing the corrosion inhibitor at a location and the nanostructure carrier is capable of releasing the corrosion inhibitor.
Claims30
A method of supplying a corrosion inhibitor to a metal, comprising:
- placing a corrosion inhibitor/nanostructure carrier combination in the vicinity of a metal;
- wherein the corrosion inhibitor/nanostructure carrier combination is capable of releasing the corrosion inhibitor.
A composition for inhibiting corrosion, comprising:
- a nanostructure carrier having a corrosion inhibitor attached forming a corrosion inhibitor/nanostructure carrier combination.
A method of preventing corrosion, comprising:
- combining a corrosion inhibitor with a nanostructure carrier;
- containing the corrosion inhibitor and nanostructure carrier within an elastomer;
- and
- placing the elastomer containing the corrosion inhibitor in the vicinity of a surface subject to corrosion;
- wherein the elastomer is permeable to the corrosion inhibitor and capable of releasing the corrosion inhibitor from the elastomer.
