Polymer Surface Characterization
This fully updated edition provides a broad approach to the surface analysis of polymers being of high technological interest. Modern analytical techniques, potential applications and recent advances in instrumental apparatus are discussed. The self-consistent chapters are devoted to techniques from photoelectron spectroscopy to electron microscopies and wettability.
Ellipsometry of Functional Organic Surfaces and Films
This new edition provides a state-of-the-art survey of ellipsometric methods used to study organic films and surfaces, from laboratory to synchrotron applications, with a special focus on in-situ use in processing environments and at solid-liquid interfaces. Thanks to the development of functional organic, meta- and hybrid materials for new optical, electronic, sensing and biotechnological devices, the ellipsometric analysis of optical and material properties has made tremendous strides over the past few years. The second edition has been updated to reflect the latest advances in ellipsometric methods. The new content focuses on the study of anisotropic materials, conjugated polymers, polarons, self-assembled monolayers, industrial membranes, adsorption of proteins, enzymes and RGD-peptides, as well as the correlation of ellipsometric spectra to structure and molecular interactions.
Polymer Sorption Phenomena
This book contains contributions of the 7th Dresden Polymer Discussion held in Mei?en near Dresden from April 19 to 22, 1999. The conference was dedicated to the field 'Characterization of polymer sorption phenomena: From solution to the surface'. Research in the area of modification and characterization of surfaces and interfaces of solids has been booming in the last few years, due to its enormous importance and potential for the development of novel technologies in materials research and engineering. Therefore the 7th Dresden Polymer Discussion, held from April 19 to 22, 1999, was dedicated to the field 'Characterization of polymer sorption phenomena: from solution to the surface'. The publication of the proceedings in this book may contribute to further progress in this field.
Spectroscopy of Rubbers and Rubbery Materials
This book deals with the application of spectroscopic techniques for characterisation of chemical and physical structures in viscoelastic materials, such as unvulcanised elastomers and their vulcanisates, various rubbery materials and some plastics, which when blended with particular additives (plasticisers) behave like rubbers. Analysis of the rubbery materials is complicated by the fact that rubbery products, such as tyres, tubes, seals, V-belts and hoses, contain in the rubbery matrix a significant amount of various compounds, i.e., fillers, vulcanising agents, antioxidants and plasticisers. Due to the complex composition, no single technique can provide a good understanding of the effect...
Funktionalisierte Blockcopolymere zur Herstellung reaktiver strukturierbarer Filme
Die Erzeugung kleinster Oberflachenstrukturen im Nanometerbereich ist durch Ausnutzung der Selbstorganisationseigenschaften von speziellen Blockcopolymeren realisierbar. Im Focus dieser Arbeit steht die Anwendung phasenstrukturierter Polymerfilme als reaktive Nanotemplate fur eine ortsaufgeloste Molekulimmobilisierung. Hierzu werden Filme entwickelt, die eine definierte Phasenstruktur aufweisen und zudem mit reaktiven Oberflachenfunktionen ausgestattet sind. Ausgehend von der Synthese von funktionalisierten Blockcopolymeren mit ausgepragter Phasenseparation wird die Herstellung und Charakterisierung von reaktiven nanostrukturierten Filmen beschrieben. Dabei stehen insbesondere Untersuchungen zur Beschaffenheit der Oberflachenmorphologie und die genaue Analyse der Grenzflachenzusammensetzung im Vordergrund. Zur Erhohung der Strukturkomplexitat ist ausserdem die Nutzung komplementarer Strukturierungsverfahren von grosser Bedeutung. In diesem Zusammenhang wird eine Strategie vorgestellt, die die Kombination von konventionellen photolithographischen Methoden mit der Strukturgebung durch Selbstorganisation ermoglicht (Hybridstrukturierung).
Correlating structure and function in small molecule organic solar cells by means of scanning probe and electron microscopy
In this work nanoscale properties in active layers of small molecule organic solar cells are studied regarding their impact on device performance. For this, the effect of variations in stack design and process conditions is examined both electrically and with high resolution imaging techniques. Two topics are addressed: (i) the visualization of charge extraction/injection properties of solar cell contacts and (ii) the tailoring of structural properties of co-evaporated material blends for bulk heterojunction (BHJ) organic solar cells. (i) We study the impact of controlled contact manipulation on the internal electric potential distribution of fluorinated zincphtalocyanine (F4ZnPc)/fullerene ...

This book helps the researchers and students in expanding their knowledge in this field.
Die glasartige Dynamik von Polymeren mit spezieller Architektur in eingeschränkter Geometrie dünner Filme
Die glasartige Dynamik in nanoskaligen Polymergeometrien ist ein hochaktuelles Forschungsgebiet, dessen Komplexitat durch zahlreiche kontroverse Ergebnisse in der Fachliteratur unterstrichen wird. Die vorliegende Dissertation liefert zu dieser Thematik einen fundierten experimentellen Beitrag, indem erstmals an emph {identisch praparierten Polymerfilmen mittels Kombination emph {unterschiedlicher Analysemethoden (Ellipsometrie, Breitband Dielektrischer Spektroskopie, Rontgenreflektometrie) die Glasubergangstemperatur (T_g) in begrenzter Geometrie dunner Filme bestimmt wurde. Folgende Aspekte, die zum Verstandnis der glasartigen Dynamik in dunnen Filmen dienen, werden in dieser Arbeit aufgegriffen: I) Welchen Einfluss haben attraktive, repulsive Grenzflachenwechselwirkungen zwischen Polymer und Substrat; II) Welche Rolle spielt die Polymerarchitektur (linear, verzweigt, hochverzweigt); III) Zeigen unterschiedliche Analysemethoden vergleichbare Ergebnisse und IV) In welcher Weise beeinflussen praparative und experimentelle Faktoren den Glasubergang in dunnen Filmen.
Ellipsometry of Functional Organic Surfaces and Films
Ellipsometry is the method of choice to determine the properties of surfaces and thin films. It provides comprehensive and sensitive characterization in contactless and non-invasive measurements. This book gives a state-of-the-art survey of ellipsometric investigations of organic films and surfaces, from laboratory to synchrotron applications, with a special focus on in-situ use in processing environments and at solid-liquid interfaces. In conjunction with the development of functional organic, meta- and hybrid materials for new optical, electronic, sensing and biotechnological devices and fabrication advances, the ellipsometric analysis of their optical and material properties has progressed rapidly in the recent years.
