Retarded condensate freezing propagation on superhydrophobic surfaces patterned with micropillars

Retarded condensate freezing propagation on superhydrophobic surfaces patterned with micropillars

Previous studies have shown ice delay on nano-structured or hierarchical surfaces with nanoscale roughness. Here we report retarded condensate freezing on superhydrophobic silicon substrates fabricated with patterned micropillars of small aspect ratio. We further investigated the pillar size effects...
