Abstract
Hydrophilic coating compositions and methods to make and use the compositions are disclosed. The compositions include a polymer comprising one or more cyanate groups and a blocking agent contacting at least one of one or more cyanate groups. When exposed to atmospheric water, the blocked cyanate moieties at the surface may hydrolyze to expose hydrophilic groups. Thus, the hydrophobic polymeric surface may change to a hydrophilic surface upon reacting with atmospheric water and moisture.
