| Materials are central to much science and engineering for all of society, from highest tech companies to the citizens' concerns about hazardous waste. Traditionally, the Materials Science and Engineering community was driven from the inner recesses of fundamental science outwards to applications engineering, technology, and a compliant public. In the new millennium all science must do an about face and be pulled by applications, the marketplace, and ultimately the public's needs. Traditional measures of performance will be replaced increasingly by "cheaper, greener, and faster" as the important criteria for much materials research. | |||

| There is currently a great deal of interest in controlling the structure and composition of materials and surfaces at the nanoscale level. This is particularly true for optically and electronically active polymers where it is anticipated that the unique properties of these materials can be successfully tailored at the molecular level if suitable techniques are developed to manipulate and control the manner in which they organize in the solid state and on surfaces. We have recently developed a new layer-by-layer molecular self-assembly process that can be used to fabricate multilayer thin films of polymers. This very simple approach, which involves the sequential adsorption of polyions from dilute aqueous solutions, can be used to coat a wide variety of polymeric and nonpolymeoic substrates with many different functionally active polymers. Since the polymer film is fabricated one molecular level at a time, it is also possible to build heterostructure thin films with complex molecular architectures and thickness that are controllable at the molecular level. It will be demonstrated that this new nanoscale approach to the processing of polymers into thin films can be used to fabricate a wide variety of electronically active thin films including light emitting devices, transparent-electrically conductive thin films, and photovoltaic devices. In addition, this approach can be used to systematically control the surface properties of materials via a simple molecular level blending process. The fabrication and properties of nano composites based on polymer/inorganic nanocrystallite multilayer thin films will also be discussed. | |||
