Abstract
Paints and coatings that change the coated surface from hydrophobic to a hydrophilic, self-cleaning surface when exposed to atmosphere are described. The compositions include a plurality of boronic acid functionalized polymers, and a blocking agent contacting at least one of the plurality of boronic acid, wherein the blocking agent is configured to be removed by a stimulus to provide a renewable hydrophilic, self-cleaning polymer coating.
Claims34
A coating composition comprising:
- a plurality of boronic acid functionalized polymers;
- and
- a blocking agent contacting at least one of the plurality of boronic acid,
- wherein the blocking agent is configured to be removed by a stimulus to provide a renewable hydrophilic, self-cleaning polymer coating.
(canceled)
7-9. (canceled)
A method for preparing a renewable hydrophilic coating composition, the method comprising:
- contacting at least one boronic acid with at least one blocking agent to form a blocked boronic acid moiety;
- contacting the blocked boronic acid moiety with an organic halide to form an ester;
- and
- polymerizing the ester to form the coating composition.
18-19. (canceled)
A method of coating a substrate, the method comprising:
- applying a coating composition to the substrate, wherein the coating composition comprises a plurality of boronic acid functionalized polymers, and
- a blocking agent contacting at least one of the plurality of boronic acid,
- wherein the blocking agent is configured to be removed by a stimulus to provide a renewable hydrophilic, self-cleaning polymer coating.
29-32. (canceled)
(canceled)
An article of manufacture comprising:
- a coating covering at least a portion of the article, wherein the coating comprises a plurality of boronic acid functionalized polymers;
- and
- a blocking agent contacting at least one of the plurality of boronic acid;
- wherein the blocking agent is configured to be removed by a stimulus to provide a renewable hydrophilic, self- cleaning polymer coating.
