Abstract

Coatings and methods of using and producing the same are provided. In an exemplary embodiment, a coating includes a first ligand and a second ligand different than the first ligand. The first ligand includes a first carboxylic moiety, a first aromatic moiety, and a first linking moiety connecting the first carboxylic moiety to the first aromatic moiety. the first linking moiety includes an alkene. The second ligand includes a second carboxylic moiety. The coating includes a metal that is a lanthanoid metal, and the coating includes a coating resin.

First claim

What is claimed is:

1. A coating comprising:
a first ligand, wherein the first ligand comprises a first carboxylic moiety, a first aromatic moiety, and a first linking moiety connecting the first carboxylic moiety to the first aromatic moiety, wherein the first linking moiety comprises an alkene;
a second ligand different than the first ligand, wherein the second ligand comprises a second carboxylic moiety;
a lanthanoid metal; and
a coating resin.

2. The coating of claim 1 wherein:
the first aromatic moiety comprises a benzene ring and one or more hydroxyl groups connected to the benzene ring.

3. The coating of claim 2 wherein the one or more hydroxyl groups is connected to the number 3, 4, or 5 carbon of the benzene ring, and wherein the first linking moiety is connected to the number 1 carbon of the benzene ring.

4. The coating of claim 1 wherein:
the first aromatic moiety comprises a benzene ring and one or more ether groups connected to the benzene ring.

5. The coating of claim 4 wherein the one or more ether groups is connected to the number 3, 4, or 5 carbon of the benzene ring, and wherein the first linking moiety is connected to the number 1 carbon of the benzene ring.

6. The coating of claim 1 wherein the first carboxylic moiety comprises a carbonyl carbon and two oxygen atoms.

7. The coating of claim 1 wherein a lanthanoid metal/ligand salt is present in the coating at from about 10 to about 25 weight percent, based on a total solids weight of the coating.

8. The coating of claim 1 wherein the first linking moiety comprises a total of two carbon atoms that are connected by a double bond.

9. The coating of claim 1 wherein the first ligand is conjugated, where a double bond between an oxygen atom and a carbonyl carbon of the first carboxylic moiety is separated from a double bond in the first linking moiety by one single bond, and wherein the double bond of the first linking moiety is separated from a benzene ring structure of the first aromatic moiety by one single bond.

10. The coating of claim 1 wherein the first linking moiety comprises more than one double bond, and wherein every double bond of the first linking moiety is separated from every other double bond of the first linking moiety by at least a single bond.

11. The coating of claim 1 wherein the second ligand further comprises a second aromatic moiety.

12. The coating of claim 11 wherein the second ligand further comprises a second linking moiety, wherein the second linking moiety is connected to the second aromatic moiety and the second linking moiety is connected to the second carboxylic moiety.

13. The coating of claim 12 wherein the second linking moiety is an alkyne.

14. The coating of claim 1 wherein the first ligand is selected from ferulate, coumarate, or a combination thereof.

15. The coating of claim 14 wherein the second ligand is phenylpropiolate.

16. The coating of claim 1 wherein the lanthanoid metal is lanthanum.

17. The coating of claim 1 wherein the lanthanoid metal is cerium.

18. The coating of claim 1 wherein the lanthanoid metal is selected from lanthanum, cerium, or a combination thereof.

19. A method of producing a coating comprising:
combining components, where the components comprise;
(a) a first ligand, wherein the first ligand comprises a first carboxylic moiety, a first aromatic moiety, and a first linking moiety connecting the first carboxylic moiety to the first aromatic moiety, wherein the first linking moiety comprises an alkene;
(b) a second ligand different than the first ligand, wherein the second ligand comprises a second carboxylic moiety;
(c) a lanthanoid metal; and
(d) a coating resin; and

mixing the components to produce the coating.

20. A method of using a coating comprising:
applying a coating over an article, wherein the coating comprises a first ligand, a second ligand different than the first ligand, a lanthanoid metal, and a coating resin, wherein the first ligand comprises a first carboxylic moiety, a first aromatic moiety, and a first linking moiety connecting the first carboxylic moiety to the first aromatic moiety, wherein the first linking moiety comprises an alkene, and wherein the second ligand comprises a second carboxylic moiety; and
curing the coating.
