Sliding of Water Droplets on Microstructured Hydrophobic Surfaces
TL;DR: The observation that the onset of water droplets sliding under gravity on inclined micropillar-structured hydrophobic surfaces always starts with detachment of the rear contact lines of the droplets from the pillar tops is reported.
Journal ArticleDOI
Condensation and jumping relay of droplets on lotus leaf
TL;DR: In this paper, the dynamic behavior of micro water droplet condensed on a lotus leaf with two-tier roughness is studied under laboratory environment, the contact angle of the micro droplet on single micro papilla increases smoothly from 80 deg to 160 deg during the growth of condensed water.

Condensation and jumping relay of droplets on lotus leaf
TL;DR: In this article, the dynamic behavior of micro water droplet condensed on a lotus leaf with two-tier roughness is studied under laboratory environment, the contact angle of the micro droplet on single micro papilla increases smoothly from 80° to 160° during the growth of condensed water.
Journal ArticleDOI
Dewetting Transitions of Dropwise Condensation on Nanotexture-Enhanced Superhydrophobic Surfaces.
TL;DR: An in situ spontaneous dewetting transition of condensed droplets occurring on pillared surfaces with two-tier roughness, from the valleys to the tops of the pillars, owing to the nanotexture-enhanced superhydrophobicity, as well as the topology of the micropillars.
Journal ArticleDOI
Drop impact upon superhydrophobic surfaces with regular and hierarchical roughness
TL;DR: In this article, the authors investigate drop impact dynamics on three types of superhydrophobic surfaces, consisting of regular micropillars, two-tier textures with nano/micro-scale roughness and hierarchical textures with random roughness, and show that the contact time is controlled by the Weber number and the roughness of the surface.
