Superomniphobic surfaces, characterized by contact angles &gt;150° and low contact angle hysteresis (“stickiness”) for both low and high surface tension liquids, have many potential applications, from stain-resistant clothing, to anti-corrosive components, to improved condensing surfaces. One particular application of interest related to environmental chemistry is the use of superomniphobic surfaces/coatings to impart scaling and fouling resistance to membrane distillation membranes used to extract water from concentrated brines. In this presentation we give an overview of recent advances in the state of the art of using nanotechnology to enable superomniphobic membranes, as well as highlight the most pressing challenges to be overcome, particularly for application in membrane distillation of concentrated brines.
