Abstract

Superhydrophobic surfaces have received significant interest for dropwise condensation to increase the efficiency of energy applications such as heat exchangers, power plants, and solar thermal energy conversion systems. While superhydrophobic surfaces can be fabricated using silane self-assembled coatings (SAC) on oxide structures, significant heat transfer enhancements require high nucleation densities that are difficult to achieve due to the high energy barrier for nuclei formation. In this work, we demonstrated that by infusing microstructured surfaces with low-surface tension oil, nucleation densities can be increased by over an order of magnitude while maintaining low droplet adhesion. This work offers a simple and scalable approach to create surfaces that can be tailored for enhanced heat transfer.
