Abstract

We report on our recent endeavor in developing superlyophobic surfaces, on which both water and hexadecane demonstrate contact angles greater than 150 degrees and, even more importantly, roll-off angles for 20-µl droplets of less than 10 degrees. Our superlyophobic surfaces are based on a multilength-scale structure, either froma raspberry-like topography or from paricle-containing woven fabrics. The multilength-scale roughness plays a major role in rendering te surfaces superoleophobic (the liquid droplets are in the Cassie wetting state), especially in terms of obtaining low hexadecane roll-off angles. In addition, surface perfluorination has proven to be essential in achieving superoleophobicity.
