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

主权项

1. A refrigerator shelf having a surface comprising a spill-resistant border that resists spills of water and of a mixture comprising oil and water, wherein the spill-resistant border comprises a roughened area treated with a composition comprising a silane that increases the hydrophobicity and oleophobicity of the roughened area, which will serve as 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 border, and wherein when the surface is level the spill-resistant border retains up to 5.9 mm of water, up to 5.2 mm of an oil and water mixture, or up to 4.7 mm of milk.
