Nanostructures And Functionalization Of Three-dimensional Assemblies

The research of self-assembled multilayer films has attracted attention of scientists from all areas in recent years. Numerous materials, including charged and uncharged materials have been incorporated into multilayers by exploiting various techniques. In general, self-assembled multilayer films exist at the interfaces of gas/liquid or liquid/solid and are easy to achieve by self-assembly techniques. In 1991, G. Decher developed a way to fabricate multilayer structures which makes full use of the electrostatic interaction between cationic and anionic groups as driving force. This technique has been proven to be a rapid and experimentally very simple way to produce complex layered structures with precise control of layer composition and thickness. It has been regarded as an important milestone for the research of multilayer films. One of the most important goals in the research of multilayer film is to understand the structure-function relationship and ultimately integrate nano-architecture and functions in one self-assembling system. Some basic problems remaining in thin film research should attract the attention of researchers: (a) monolayer and multilayer architecture, including composite films, (b) diffusion controlled interfaces, (c) control over the monolayer thickness, (d) patterning formation, (e) phase transition, (f) charge and energy transfer between layers, (g) stability, etc. The research work of this dissertation mainly focuses on three aspects: (1) to fabricate multilayer films composing of cationic poly(4-vinylpyridine) complex...
