Microtexture Supported Ionic Liquid Films Showing Excellent Dynamic Omniphobicity Under Harsh Conditions

摘要

The development of self-cleaning, highly water and oil repellant surfaces (dynamically omniphobic) has been the subject of intense study. Smooth, "liquid-like" or liquid-infused surfaces2 easily repel contaminant liquids due to their very low contact angle hysteresis. Here, an ionic liquid (IL) film supported by a microtextured, porous surface has excellent dynamic omniphobicity and retains this capability after exposure to several harsh conditions.
