Multi-layer ultrathin polymer films have been deposited on the surfaces of nanoparticles of alumina using a plasma polymerization treatment. The nanoparticles ranged from 10-150 nm in spherical shapes. High-resolution transmission electron microscopy (HRTEM) experiments showed that an extremely thin film of the pyrrole layer (10-20 A) was uniformly deposited on the surfaces of the nanoparticles. in particular, the particles of all sizes (10-150 nm) exhibited equally uniform ultrathin films indicating well-dispersed nanoparticles in the fluidized bed during the plasma treatment. After single layer coating, hexamethyldisiloxane (HMDSO) was coated again as a second layer onto the surface of pyrrole. Subsequently, a third layer of pyrrole was coated on the top of HMDSO film completing the multi-layer coating process. Time-of-Flight Secondary ion mass spectroscopy (TOFSIMS) experiments confirmed the deposition of these multi-layer thin films on the nanoparticles. The deposition mechanisms and the effects of plasma treatment parameters are discussed.

Interest in research on nanoscale materials is steadily increasing: nano-structured magnetic materials exhibit new and interesting physical properties, which cannot be found in the bulk. Many of these unique properties have great potential for technical applications in magneto-sensors, bio-sensors, magneto-electronics, data storage, magnetic heads of computer hard disks, single-electron devises, microwave electronic devices, etc. Current research concentrates on device design, synthesis and the characterization of nanostructured materials. The contributions to this book concentrate on magnetic properties of nanoscale magnetic materials, especially on fabrication and characterization, and the physics underlying the unique properties of these structures and devices.

There has been an increasing need and great interest in both fundamental science and cutting-edge technology to modify the surfaces of nanoparticles. Such a surface modification must be within a nanoscale in terms of structure, composition, and uniformity. The great challenge therefore lies critically on the deposition of a film on the order of a few nanometers on the surfaces of the nanoparticles. In this thesis, the uniform deposition of ultrathin polymer films of 2 nm on the surfaces of alumina nanoparticles by plasma polymerization was demonstrated. The deposited film can also be tailored to multi-layers. One layer to three layers has been tried in the experiments. Scanning Electron Microscopy (SEM), High Resolution Electron Microscopy (HREM), Time-of-flight Secondary Ion Mass Spectroscopy (TOF-SIMS), X-ray Diffraction (XRD) and Micro hardness were used to confirm the pyrrole coating on the nanoparticle surfaces, the surface morphology and the mechanical properties. Using such a nanocoating, it opens a window to alter the intrinsic properties of materials that cannot be achieved by conventional methods and materials.

Materials scientists are often faced with the problem of modifying surfaces of objects, yet keeping their shape and properties. This book provides a detailed survey on the new technology of adsorption from solution for the fabrication of molecularly ordered multicomposite films in order to replace and expand on the well known Langmuir-Blodgett technology and to open the field of molecular self-assembly to materials and biosciences. The book is aimed at scientists who want to integrate several different functional entities in a single device. To this audience it presents the technique of layer-by-layer assembly as today's most powerful key technology, which is low cost, solution based and very robust. It is already beginning to make the transition from academic research into industrial mass production.

There has been an increasing need and great interest in both the fundamental science and the cutting-edge technology to modify the surfaces of nanoparticles. Such a surface modification must be done at the nanoscale in terms of structure, composition, and uniformity. The great challenge therefore lies critically on the deposition of a film on the order of a few nanometers on the surfaces of the nanoparticles. In this thesis, the uniform deposition of ultrathin polymer films of 2-10 nm on the surfaces of nanoparticles and nanotubes by plasma polymerization was demonstrated. The deposited film can also be tailored to different compositions. High Resolution Electron Microscopy (HREM), Time-of-flight Secondary Ion Mass Spectroscopy (TOF-SIMS), Infrared Spectroscopy (IR) and other tests were used to confirm the polymer coating on the nanoparticle surfaces. Other tests, such as Contact Angle and ion exchange, were used to test the surface properties of the modified nanoparticles.

This study is focused on the fabrication of plasma polymerized ultrathin films and the elucidation of their unique properties with an emphasis on the solvent-less, dry polymerization process to introduce post-deposition functionality, robustness, and shape preservation. Two major classes of materials are the subject of this study: biological monomers, specifically the amino acids tyrosine and histidine and synthetic organic and inorganic monomers including acrylonitrile, 2-hydroxyethyl methacrylate, N-isopropylacrylamide, titanium isopropoxide and ferrocene. The unique chemical and physical properties of highly cross-linked ultrathin plasma polymerized amino acid and synthetic polymer films are demonstrated along with their functional response and robustness on both planar and complex surface structures. The work emphasizes the facile ability of plasma polymerization to create unique, tailored ultrathin coatings. Chemical functionality retention (OH, NH2) of the tyrosine and histidine amino acids is demonstrated by the subsequent mineralization of gold or titania nanoparticles on the plasma polymerized ultrathin films using a wet chemical approach. Inorganic nanoparticle mineralization is further investigated as a method to modify the optical properties of composite nanocoatings. Plasma co-polymerization of tyrosine and synthetic monomers is used to create nanocomposite coatings with unique surface functionalities, responsive behavior, optical characteristics and a high level of integration between monomers. The fabrication of novel plasma polymerized Janus microspheres, micropatterned substrates and free-standing films also demonstrate numerous plasma polymerized materials which exhibit unique structural properties. Overall, facile plasma polymerization of novel, functional ultrathin films and complex topological coatings having potential biocompatible and optical applications is established.
