Recent years have seen significant advances in the understanding of super-repellent surfaces, i.e., surfaces with extreme repellency to liquids. Surfaces with extreme repellency to high surface tension liquids like water are considered to be superhydrophobic. Surfaces with extreme repellency to low surface tension liquids like oils and alcohols are considered to be superoleophobic. Surfaces that are both superhydrophobic and superoleophobic are considered superomniphobic, i.e., extremely repellent to virtually any liquid.

In this presentation, the fundamental chemical and physical principles of designing super-repellent surfaces will be discussed. Based on these fundamental principles, applications of super-repellent surfaces in minimization of food waste, condensation heat transfer, chemical shielding, enhanced hemocompatibility, inexpensive diagnostics, and rewritable liquid patterns and liquid-liquid separations will be discussed.


Prof. Arun K. Kota received a B.S. in Chemical Engineering from Andhra University in 2001, M.S. in Chemical Engineering from Clarkson University in 2003, and Ph.D. in Mechanical Engineering from the University of Maryland in 2008. Prior to joining Colorado State University in 2013, he was a Postdoctoral Fellow in Materials Science and Engineering at the University of Michigan. His work has so far resulted in 6 patents and about 40 publications, which are cited 2300+ times. His work was highlighted by Bloomberg TV, NBC News, Wall Street Journal, Washington Times, Forbes and several other prestigious newspapers, magazines and websites. He received the NSF Career Award (2018), the Summer Faculty Fellowship from Air Force Office of Scientific Research (2016), the Teaching Excellence Award from Colorado State University (2016) and the Best Science Paper Award from the Institution of Civil Engineers (2014).
