Controlling Droplet Impact Dynamics by Nanopatterning Surfaces
Invention type: Technology
/
Case number: #14716
This invention relates generally to an article that includes a non-wetting surface having a dynamic contact angle of at least about 90°. The surface is patterned with macro-scale features configured to induce controlled asymmetry in a liquid film produced by impingement of a droplet onto the surface, thereby reducing time of contact between the droplet and the surface.
