COMPOSITION OF HYDROPHILIC PAINTED SURFACE

摘要

Paint configured to provide a hydrophilic paint surface comprising a paint base and a texture imprinting additive (TIA) that provides sacrificial particles upon drying of the paint. Loss of the sacrificial particles increases roughness and reduces the contact angle with water, providing a hydrophilic surface that is wettable and hence self-cleaning. Also described are specific types of TIA, methods of making the paint, methods of making a hydrophilic surface, and kits.

主权项

1. A paint, which is configured to provide a hydrophilic painted surface, comprising:
a paint base; a texture imprinting additive (TIA), wherein the TIA is configured to provide sacrificial particles upon drying of the paint; wherein the TIA comprises one or more of a water soluble solid, a photodegrading material, an oxygen-degrading material, or a combination thereof; wherein the water soluble solid comprises at least one of a sugar, an organic salt, an inorganic salt, or a combination thereof; wherein the TIA has an average particle size in a range from about 0.001 μm to about 200 μm.
