SUMMARY:Towards Durable Hydrophobicity and Omniphobicity  - Nenad Miljkovi

DESCRIPTION:Micro and nanoengineered functional surfaces have recently rec
 eived significant attention due to their ability to enhance the efficiency
  and performance of a variety of applications. Although demonstrated on th
 e lab scale\, the successful integration of these surfaces into systems ha
 s been slow due mainly to issues related to poor longevity\, unproven scal
 ability\, and inability to handle working fluids having low surface tensio
 ns. Furthermore\, the utilization of these surfaces in thermal domains has
  been even tougher due to the need to keep coatings ultra-thin to avoid ad
 ding parasitic thermal resistances. In this talk\, I will discuss fundamen
 tal studies of hydrophobic and omniphobic surface durability during both w
 ater vapor condensation and a variety of fluid-surface interactions. Our s
 tudies provide key insights related to the design of smooth and rough func
 tional surfaces and help pinpoint future breakthroughs needed to improve t
 he robustness and implementation of hydrophobic and omniphobic coatings.
