Spill Resistant Surfaces Having Hydrophobic and Oleophobic Borders

摘要

Described herein are methods for creating spill-proof or spill-resistant surfaces through the use of hydrophobic or oleophobic (H-SH) edges, borders and/or boundaries that contain the water and other liquids within the inside edges, borders and/or boundaries. Also described herein are spill-proof/spill-resistant surfaces. Liquid (e.g., water and other aqueous solutions/suspensions) heights of 3-6 mm on a level planar surface can be sustained by such edges, borders and/or boundaries. The H-SH borders can be created on glass, metal, wood, plastic, and concrete surfaces.

1. A method for forming a spill-resistant border on a refrigeration shelf surface comprising activating a portion of the surface by etching or abrading it to form a roughened area on the surface and applying a composition to at least a portion of the roughened area on the surface that increases the hydrophobicity and oleophobicity of at least a portion of the roughened area on the surface that forms the spill-resistant border,
wherein said spill-resistant border forms a perimeter around at least one area that has a lower hydrophobicity and lower oleophobicity than the spill-resistant border; and wherein the composition comprises a silanizing agent that covalently binds the roughened area.
