| The effect on static and dynamic contact angles of Langmuir-Blodgett films deposited on a solid substrate was investigated. Langmuir-Blodgett films are highly ordered and compact ultra-thin films, one molecule thick with outstanding physical and chemical properties. Langmuir-Blodgett films are manufactured in a Langmuir trough where amphiphilic molecules are deposited at the air/water interface and subsequently transferred onto a solid substrate by immersing and removing the solid substrate through the air/water interface.; Dynamic wetting, the flow of a liquid over a solid surface originally in contact with air, strongly depends on molecular interactions between the bulk phases and the solid-liquid and air-liquid interfaces. Wetting phenomena are ubiquitous in many natural and industrial processes. The dynamics of wetting and moving three-phase contact lines has been recognized as a main factor in boiling and condensation phenomena. (Abstract shortened by UMI.)... |
