Omniphobic Lubricant-Infused Surfaces for Improved Surface Smoothness
This patent pending technology involves a fabrication process where an omniphobic liquid-infused surface (OLIS) is used to manufacture smoother topographical surfaces. This process can be used when casting a liquid material (either molten or in solution) onto a solid substrate containing a rough surface. A liquid lubricant is placed onto the mold, covering the roughness of the solid mold and acts as a smooth interface between the mold and the foreign liquid material. Upon hardening of liquid material by a physical change or a chemical reaction, the solid material exhibits smoother surface topography, in comparison to that of the original mold. This manufacturing process can be adopted in inject molding of plastics and polymers, or the casting of metals, or ceramics, where the master mold has been fabricated with pores or roughness due to their fabrication processe
