"Synthesis, Processing, and Mechanical Behavior of Nanocomposite Thin Films"

A nanocomposite can be defined as a multiphase material with a characteristic microstructural length scale that is less than or of order 100 nm. This length scale can be, for example, the layer thickness in a multilayered material or the diameter of a second phase particle in a particle-reinforced composite. Thin film deposition methods can be used to produce a wide variety of nanocomposites in a highly controlled manner. Because of their unique microstructure, nanocomposite thin films display unusual and often enhanced properties relative to bulk materials. As an example, nanocomposites often possess unique mechanical behaviors that have potential technological applications as structural materials and hard coatings. The synthesis and processing of nanocomposite thin films by novel sputtering and electrochemical deposition techniques will be presented. The mechanical behavior of these materials, as investigated using nanoindentation, internal fraction, and fatigue testing methods, will also be discussed. Finally, a new method for manipulating and patterning in solution nanowires obtained electrochemically produced polymer-matrix composites will be presented.
