Abstract
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.
