Abstract

On a hierarchical polymer surface consisting of microposts and nanopillar arrays, water droplets are nucleated and grown selectively in the grooves between the microposts as the vapor pressure increases, whereas water droplets are randomly nucleated on a flat surface and surfaces consisting of microposts or nanopillars only.
