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.
Claims17
A method of preparing a lubricant infused surface for droplet formation comprising:
- providing a surface;
- selecting a lubricant suitable for the surface based on surface energy criteria that the lubricant has an affinity towards the surface;
- and
- exposing the surface to the selected lubricant to form the lubricant infused surface.
1 more element
A method of droplet formation comprising:
- exposing a lubricant infused surface to a vapor, the lubricant infused surface being selected as suitable for the surface based on surface energy criteria that the lubricant has an affinity towards the surface.
A lubricant infused surface comprising:
- a surface and a lubricant infused into the surface, the surface being selected based on surface energy criteria that the lubricant has an affinity towards the surface.
