Droplet evaporation on superhydrophobic surfaces

Over the last decades, a fabulous variety of synthetic superhydrophobic surfaces have been created, offering unique anti-wetting properties. A significant focus for these has on their stay-dry and self-cleaning However, unless in saturated environment, water droplets lose mass through evaporation this itself is field interest, which illustrated by flood recent studies surface contamination potential transmission infection evaporating sessile during Covid-19 pandemic. Superhydrophobic alter droplet's contact with substrate surrounding thus changing pinning heat transfer The droplet shape also alters space into vapor can diffuse. Despite many excellent reviews surfaces, there does not appear to overlap droplets. Here, we address gap outlining diffusion-limited theory, applications patterned effect evaporative cooling drop rates, practical such as nanoparticle assembly, biomedical assay, analytical chemistry, crystallization applications. Finally, provide our personal views possible future directions overlapping areas.
