Condensation and Wetting Behavior on Surfaces With Micro-Structures: Super-Hydrophobic and Super-Hydrophilic
Recently it has become possible to achieve radical manipulation of surface wettability, and wettability is known to play a key role in the retention of condensate and frost melt on heat exchanger surfaces. In this paper we present a review of methods to produce such surfaces, and we describe a super-hydrophobic surface, with a contact angle of 148°, created in our lab. We describe surfaces with...
متن کاملRemodeling of Super-hydrophobic Surfaces.
An experimental study on the underlying mechanisms of structured super-hydrophobic surfaces was recently published [ Butt, H.-J.; et al. How Water Advances on Superhydrophobic Surfaces. Phys. Rev. Lett. 2016, 116, 096101 . DOI: 10.1103/PhysRevLett.116.096101 ]. After depositing small drops of water, Butt's group inclined their surfaces to initiate movement. They examined the contact between the...
متن کاملHierarchical micro/nano structures for super-hydrophobic surfaces and super-lyophobic surface against liquid metal
Non-wetting super-hydrophobic or super-lyophobic surfaces are of great interest in a variety of applications. Natural water repelling surfaces show micro-/nanocombined hierarchical structure which shows extremely low wettability and self-cleaning characteristics. Inspired by such natural wonders, there have been tremendous efforts to create artificial non-wetting super-hydrophobic or super-lyop...
متن کاملBounds on Contact Angle Hysteresis of Textured Super-hydrophobic Surfaces
This paper presents the fabrication of rough super-hydrophobic surfaces, dynamic measurements of sliding angles of water droplets, and a modeling approach to estimate bounds on contact angle hysteresis—the major dissipative mechanism in droplet based microfluidic systems. We investigate the dependence of hysteresis on texture parameters, evaluate the current model, propose a modification, and s...
متن کاملThe Study of Super Hydrophobic Surfaces Using High Speed Shadowgraphy
The aim of this article is the measurement of the basic characteristic of superhydrophobic surfaces using high speed shadowgraphy. Here we describe the novel patented system for the industrial production of superhydrophobic surfaces. These surfaces were investigated with two optically based measurement methods: impinging drop and inclined wall. The results of the visualization and analysis help...
