2 results about "Dewetting" patented technology

In fluid mechanics, dewetting is one of the processes that can occur at a solid–liquid, solid-solid or liquid–liquid interface. Generally, dewetting describes the process of retraction of a fluid from a non-wettable surface it was forced to cover. The opposite process—spreading of a liquid on a substrate—is called wetting. The factor determining the spontaneous spreading and dewetting for a drop of liquid placed on a solid substrate with ambient gas, is the so-called spreading coefficient S: S =γSG-γSL-γLG where γSG is the solid-gas surface tension, γSL is the solid-liquid surface tension and γLG is the liquid-gas surface tension (measured for the mediums before they are brought in contact with each other).
