Book Description
Very thin film materials have emerged as a highly interesting and useful quasi 2D-state functionality. They have given rise to numerous applications ranging from protective and smart coatings to electronics, sensors and display technology as well as serving biological, analytical and medical purposes. The tailoring of polymer film properties and functions has become a major research field. As opposed to the traditional treatise on polymer and resin-based coatings, this one-stop reference is the first to give readers a comprehensive view of the latest macromolecular and supramolecular film-based nanotechnology. Bringing together all the important facets and state-of-the-art research, the two well-structured volumes cover film assembly and depostion, functionality and patterning, and analysis and characterization. The result is an in-depth understanding of the phenomena, ordering, scale effects, fabrication, and analysis of polymer ultrathin films. This book will be a valuable addition for Materials Scientists, Polymer Chemists, Surface Scientists, Bioengineers, Coatings Specialists, Chemical Engineers, and Scientists working in this important research field and industry.

Book Description
Polymers have been used in thin film coatings as a way to produce tailor made surfaces. These thin films have been explored for use in a variety of applications to produce antifouling coatings, corrosion resistant coatings, biocompatible surfaces, and biomedical devices. Polymer brushes, polymer chains tethered to a substrate or surface, synthesized by surface-initiated polymerization have gained significant attention in recent years. As brushes offer a new pathway towards the preparation of functional surfaces and offer long term stability, even in adverse environments, they are attractive for use as high-tech coatings. Patterned polymer thin films have also seen growing interest for various applications. This dissertation will focus on the top-down direct patterning of polymer brushes and the bottom-up self-assembly of block copolymer thin films. A new approach to creating patterned polymer brushes is highlighted, which is a simpler approach than what is conventionally done. Various polymer brushes were patterned directly using electron beam lithography to create high resolution patterned polymer brushes in a single step. This method was then used to demonstrate the unique ability to create sub-surface patterns within the brush. Additionally, direct patterning was used to create high resolution patterned binary polymer brushes of PMMA and PEGMA. With this binary patterned surface, a surface that responds to its local environment was created. This thesis also details characterization techniques used in probing polymer thin films to better understand how to improve block copolymer self-assembly. By using a powerful technique called grazing incidence small angle X-ray scattering (GISAXS) on solvent vapor annealed block copolymer thin films while monitoring the solvent vapor swollen film thickness and controlling the film swelling with a nitrogen counterflow, the work presented demonstrates how to accurately determine the processing conditions necessary for the annealing process to take place. This process also provides information as to what changes are occurring during the annealing process. Another characterization technique known as near edge X-ray absorption fine structure (NEXAFS) is also highlighted. A more exact calculation of the electron escape depth (EED) for NEXAFS is done using polymer brushes as the calibration sample. With this information, we can do composition depth profiling on our polymer thin films to identify what is at the surface.

Book Description
"Polyaniline (PAni), an inherently conducting polymer, was synthesized with different intrinsic oxidation states from emeraldine salt (ES) and emeraldine base (EB) to leucoemeraldine base (LM). Free-standing membranes and thin film bi-layers of metal-polyaniline were fabricated by magnetron sputter deposition of aluminum, copper, titanium and iron onto the polyaniline films. Metal-polyaniline samples were analyzed by scanning electron microscopy (SEM) and transmission electron microscopy (TEM) to investigate the microstructures of specimens. Auger electron spectroscopy (AES) and X-ray photoelectron spectroscopy (XPS) were employed to study the chemical bonding and interactions between depsoited metals and polyaniline at the interfaces. Acoustic transmission properties of metal-polyaniline membranes were characterized by measuring the insertion loss as a function of acoustic frequencies and membrane geometry in various testing environments. Results indicated that the type of metal and the intrinsic oxidation state of the polyaniline influenced the structures and chemistry of the metal-polyaniline interfaces and membranes"--Abstract, leaf iii.

Book Description
Contains papers from an April 1997 symposium held in San Francisco, California. Contributions are divided into sections with initial emphasis on structures (monolayers, supramolecular assemblies, and nanostructures) followed by applications (photonics, microlithography, and microelectronics packaging). Specific topics include polymer- supported biomembrane models, glass transition in ultrathin polymer films, mechanistic studies of chemically amplified resists, and polymeric organic-inorganic hybrid nanocomposites.
