Abstract
Described herein are articles coated with one or more polyelectrolyte complexes. The polyelectrolyte complexes have a high glass transition temperature when the coating is contacted with an aqueous medium. In one aspect, the coating has a glass transition temperature of at least 45° C. when in contact with an aqueous medium, which makes the coatings described herein as “glassy.” The coating compositions described herein are effective in reducing adhesion of organisms on the surface of the coated article, which makes the coatings an effective antifouling coating.
Claims20
An article comprising a coating for reducing fouling on a surface of an article, wherein the coating comprises a polyelectrolyte complex comprising at least one negatively charged polyelectrolyte polymer, at least one positively charged polyelectrolyte polymer, and wherein the coating has a glass transition temperature of at least 45° C. when in contact with an aqueous medium.
An article comprising a coating for reducing fouling on a surface of an article, wherein the coating is produced by the method comprising applying to the surface of the article a coating comprising a polyelectrolyte complex, the method comprising applying to the surface a composition comprising at least one negatively charged polyelectrolyte polymer, at least one positively charged polyelectrolyte polymer, and a solvent, and wherein the coating has a glass transition temperature of at least 45° C. when in contact with an aqueous media.
An article comprising a coating for reducing fouling on a surface of an article, wherein the coating is produced by the method comprising sequentially applying to the surface of the article at least one negatively charged polyelectrolyte polymer composition and at least one positively charged polyelectrolyte polymer composition, and wherein the coating has a glass transition temperature of at least 45° C. when in contact with an aqueous media.
