Surfaces with special wettability have been amply studied due to their implications in various disciplines. The existing theory requires both surface chemistry and surface roughness to generate super liquid-repellency. Through another project on micro rotary stage, we have learned that the detailed geometries of roughness might dictate the surface wettability. Such recognition has instigated our development of a structure-based super-repellent surface free from any surface chemistry. By decoding the secret of liquid-repellency on structured surfaces from the details of the liquid- solid-air interface, and creating a novel 3-D micro- and nano-fabrication (Figure), we have successfully repelled ALL liquids, including those with the lowest known surface tension and completely wet even the most hydrophobic material such as Teflon . This not only revises the current understanding by freeing one from the necessity of hydrophobic materials but also opens up a host of versatile new applications. For example, since our surface is free of any hydrophobic coating, it withstands extremely high temperatures (>1000°C) and resists biofouling.
