Premetered Coating Methods

This book compares premetered methods to self-metered processes and addresses general properties of premetered methods. It presents specific properties of slot, slide, and curtain coating. The book is divided in three parts: Part I compares premetered methods to self-metered processes. It explains the term “premetered,” which is an expression of the law of mass conservation, and discusses the physical fluid properties that are relevant for premetered processes. Furthermore, it presents in detail the various basic flow fields that make up premetered coating methods. Lastly, it introduces the concepts of wall shear stress, residence time, and hydrodynamic assist to dynamic wetting. Part II addresses general properties of premetered methods, such as the fluid conditioning and delivery systems, the nominal film thickness, and the film thickness uniformity, both in machine and cross-web directions (die design). It lists the attractive features of simultaneous multilayer applications, including an explanation of how mixing of adjacent layers can be prevented. This section concludes by revisiting examples of economic considerations. Part III presents specific properties of slot, slide, and curtain coating. It examines various topics, such as coating equipment and coating configurations, coating modes, details of the various flow fields, operating window and process limitations, and process optimization.

Eine in sich geschlossene, umfassende Einführung in die Grundlagen der Grenzflächenphänomene und ihrer Anwendung auf Prozesse und Produktdesign - geschrieben für Ingenieure aus Chemie, Elektronik und Biomedizin. Zwischenmolekulare Wechselwirkungen an der Grenzfläche werden ausführlich behandelt; Eigenschaften, Verarbeitung und Verhalten fluider Grenzflächen werden ebenso diskutiert wie Ober- und Grenzflächenmerkmale fester Stoffe. Dieses Buch ist relevant für den Praktiker in der Industrie, stellt aber gleichzeitig eine wertvolle Hilfe für Lehrkräfte ingenieurwissenschaftlicher Fachrichtungen bei der Ausbildungsplanung dar.

Organic light emitting diodes (OLEDs) have attracted enormous attention in the recent years because of their potential for flat panel displays and solid state lighting. This potential lies in the amazing flexibility offered by the synthesis of new organic compounds and by low-cost fabrication techniques, making these devices very promising for the market. The idea that flexible devices will replace standard objects such as television screens and lighting sources opens, indeed, a new scenario, where the research is very exciting and multidisciplinary. The aim of the present book is to give a comprehensive and up-to-date collection of contributions from leading experts in OLEDs. The subjects cover fields ranging from molecular and nanomaterials, used to increase the efficiency of the devices, to new technological perspectives in the realization of structures for high contrast organic displays and low-cost organic white light sources. The volume therefore presents a wide survey on the status and relevant trends in OLEDs research, thus being of interest to anyone active in this field. In addition, the present volume could also be used as a state-of-the-art introduction for young scientists.

A single-volume resource featuring state-of-the art reviews of key elements of the roll-to-roll manufacturing processing methodology Roll-to-roll (R2R) manufacturing is an important manufacturing technology platform used extensively for mass-producing a host of film-type products in several traditional industries such as printing, silver-halide photography, and paper. Over the last two decades, some of the methodologies and know-how of R2R manufacturing have been extended and adapted in many new technology areas, including microelectronics, display, photovoltaics, and microfluidics. This comprehensive book presents the state-of-the-art unit operations of the R2R manufacturing technology, providing a practical resource for scientists, engineers, and practitioners not familiar with the fundamentals of R2R technology. Roll-to-Roll Manufacturing: Process Elements and Recent Advances reviews new developments in areas such as flexible glass, display, and photovoltaics and covers a number of process innovations implemented recently to extend and improve the capabilities of traditional R2R lines. It covers such topics as: coating and solidification processes, in-line vacuum deposition, drying, web handling and winding, polymer film substrates, novel hybrid composite films, flexible solar cells and more. Additionally, this book: Examines key elements (unit operations) of the R2R technology, and discusses how these elements are utilized and integrated to achieve desired process efficiencies in a host of applications. Illustrates several established and novel application areas where R2R processing is utilized in current or future products. Discusses process design methodology and key advantages of R2R manufacturing technology over batch or sheet-to-sheet operations. Roll-to-Roll Manufacturing: Process Elements and Recent Advances is an ideal book for undergraduate and graduate students in various science and engineering disciplines, as well as for scientists, engineers, and technical and business leaders associated in any way with the development, commercialization, and manufacture of a variety of film products.
