title: Wetting behavior on hexagonally close-packed polystyrene bead arrays with different topographies.
abstract: Herein, we investigated the wetting behavior of hexagonally close-packed polystyrene bead arrays with different bead diameters and surface flatness. The contact angle was found to be influenced by the surface roughness as well as the contact area of the polystyrene bead array with a water droplet.
