Abstract

An anti-icing coating can include an amphiphilic copolymer on a surface of an article.

Claims (19)

1. An anti-icing article comprising a coating including polymer film composition including a matrix polymer blended with an amphiphilic copolymer on a surface of the article such that the polymer film serves as a matrix reservoir for replenishing amphiphilic copolymer molecules from a surface.

2. The article of claim 1 , wherein the matrix polymer includes a polydimethylsiloxane elastomer, an epoxy, a polyurethane or a fluorinated polyurethane.

3. The article of claim 1 , wherein the amphiphilic copolymer includes a polyethylene glycol copolymer.

4. The article of claim 3 , wherein the polymer composition includes less than 10% of the polyethylene glycol copolymer.

5. The article of claim 3 , wherein the polymer composition includes less than 5% of the polyethylene glycol copolymer.

6. The article of claim 3 , wherein the polymer composition includes less than 3% of the polyethylene glycol copolymer.

7. The article of claim 3 , wherein the polymer composition includes about 1% of the polyethylene glycol copolymer.

8. The article of claim 3 , wherein the polyethylene glycol copolymer includes a polysiloxane-polyethylene glycol copolymer.

9. The article of claim 8 , wherein the matrix polymer includes polydimethylsiloxane.

10. A method of forming an anti-icing coating a surface of an article, comprising

depositing a polymer film composition including a matrix polymer blended with an amphiphilic copolymer on a surface such that the polymer film serves as a matrix reservoir for replenishing amphiphilic copolymer molecules from a surface.

11. The method of claim 10 , wherein the matrix polymer includes a polydimethylsiloxane elastomer, an epoxy, a polyurethane or a fluorinated polyurethane.

12. The method of claim 10 , wherein the amphiphilic copolymer includes a polyethylene glycol copolymer.

13. The method of claim 12 , wherein the polymer composition includes less than 10% of the polyethylene glycol copolymer.

14. The method of claim 12 , wherein the polymer composition includes less than 5% of the polyethylene glycol copolymer.

15. The method of claim 12 , wherein the polymer composition includes less than 3% of the polyethylene glycol copolymer.

16. The method of claim 12 , wherein the polymer composition includes about 1% of the polyethylene glycol copolymer.

17. The method of claim 12 , wherein the polyethylene glycol copolymer includes a polysiloxane-polyethylene glycol copolymer.

18. The method of claim 17 , wherein the matrix polymer includes polydimethylsiloxane.
