Abstract
Lubricant infused surfaces (LIS) can be uncoated high-surface-energy solids, thereby eliminating the need for unreliable low-surface-energy coatings and resulting in LIS repelling the lowest surface tension impinging fluid (butane, γ≈13 mN/m) reported to date.
Claims13
A method of preparing a lubricant infused surface for droplet formation comprising:
- providing a solid surface;
- selecting a lubricant;
- and
- exposing the solid surface to the selected lubricant by directly applying to the solid surface to form the lubricant infused surface without applying a low-surface-energy coating to the surface, wherein the lubricant infused surface repels fluids with a surface tension of less than 17 mN/m.
1 more element
A method of droplet formation comprising:
- exposing a lubricant infused surface to a vapor, and
- wherein the lubricant infused surface is formed by directly applying the lubricant to a solid surface without applying a low-surface-energy coating to the solid surface, wherein the lubricant infused surface repels fluids with a surface tension of less than 17 mN/m.
A lubricant infused surface comprising:
- a surface and a lubricant infused into the surface,
- the lubricant infused surface having the lubricant directly on the surface,
- wherein the lubricant infused surface repels fluids with a surface tension of less than 17 mN/m.
