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.
Claims19
A coating composition comprising:
- a pigment;
- a coalescing agent;
- a polymer with a plurality of boronic acid functional groups;
- and
- a blocking agent contacting at least one of the plurality of boronic acid functional groups,
- wherein the blocking agent is configured to be removed by a stimulus to provide a renewable hydrophilic, self-cleaning polymer coating.

A method of coating a substrate, the method comprising:
- applying a coating composition to the substrate, wherein the coating composition comprises a pigment, a coalescing agent, a polymer with a plurality of boronic acid functional groups, and a blocking agent contacting at least one of the plurality of boronic acid functional groups;
- and
- removing the blocking agent by a stimulus to provide a renewable hydrophilic, self-cleaning polymer coating.
An article of manufacture comprising:
- a coating covering at least a portion of the article, wherein the coating comprises a pigment, a coalescing agent, a polymer with a plurality of boronic acid functional groups;
- and
- a blocking agent contacting at least one of the plurality of boronic acid functional groups;
- wherein the blocking agent is configured to be removed by a stimulus to provide a renewable hydrophilic, self- cleaning polymer coating.
