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 surface of a refrigerator shelf comprising: (a) roughening a portion of the surface that will serve as the spill-resistant border on the shelf; and(b) applying a silane or fluorosilane silanizing agent to the portion of the surface that will serv
1. A method for forming a spill-resistant border on a surface of a refrigerator shelf comprising: (a) roughening a portion of the surface that will serve as the spill-resistant border on the shelf; and(b) applying a silane or fluorosilane silanizing agent to the portion of the surface that will serve as the spill-resistant border on the shelf, thereby increasing the hydrophobicity and oleophobicity of said portion of the surface that will serve as the spill-resistant border,wherein said spill-resistant border is visible and forms a perimeter around at least one area that has a lower hydrophobicity than the border, andwherein, 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. 2. The method of claim 1, further comprising activating at least one part of said portion of said surface that will serve as a border prior to said applying the silane or fluorosilane, wherein the activating comprises etching with a chemical agent or abrading the surface. 3. The method of claim 2, further comprising applying a mask to said surface before said activating, before said applying the silane or fluorosilane, or before both said activating and said applying the silane or fluorosilane. 4. The method of claim 3, wherein said activating comprises etching the surface with a chemical agent or treating it with abrasive particles. 5. The method of claim 1, wherein said surface is glass. 6. The method of claim 1, wherein said spill-resistant border provides a retention of ≧3.0 mm of water or an oil and water mixture. 7. The method of claim 1, wherein said silane or fluorosilane silanizing agent comprises a fluoroalkyl group. 8. The method of claim 7, wherein said silane is tridecafluoro-1,1,2,2-tetrahydrooctyl trichlorosilane. 9. The method of claim 1, wherein the roughening a portion of the surface is conducted by etching or sandblasting. 10. The method of claim 1, wherein said silane is tridecafluoro-1,1,2,2-tetrahydrooctyl trichlorosilane. 11. A method for forming a hydrophobic and oleophobic spill-resistant border on a surface of a refrigerator shelf comprising binding particles to regions on the refrigerator shelf that will serve as the border to form bound particles; wherein the bound particles are treated with a silane or fluorosilane silanizing agent and said border forms a perimeter around at least one area of the surface that has a lower hydrophobicity and lower oleophobicity than the border; andwherein the spill-resistant border is visible and retains up to 3.1 mm of water, up to 3.6 mm of an oil and water mixture, or up to 2.3 mm of milk when the surface is level. 12. The method of claim 11, wherein the shelf is comprised of glass. 13. The method of claim 11, wherein the particles of the hydrophobic and oleophobic regions comprise particles treated with a silanizing agent. 14. The method of claim 11, wherein the particles bound to the hydrophobic and oleophobic regions comprise particles treated with a fluorosilane. 15. The method of claim 14, where the fluorosilane is tridecafluoro-1,1,2,2-tetrahydrooctyl trichlorosilane. 16. The method of claim 14, wherein the height of water retained by the border is at least 3.0 mm. 17. The method of claim 15, wherein the height of water retained by the border is at least 3.0 mm. 18. The method of claim 2, wherein said silane or fluorosilane is tridecafluoro-1,1,2,2-tetrahydrooctyl trichlorosilane. 19. The method of claim 11, wherein said silane or fluorosilane is tridecafluoro-1,1,2,2-tetrahydrooctyl trichlorosilane. 20. The method of claim 11, wherein said silane is tridecafluoro-1,1,2,2-tetrahydrooctyl trichlorosilane. 21. The method of claim 13, wherein said silane is tridecafluoro-1,1,2,2-tetrahydrooctyl trichlorosilane.
