Polyelectrolyte Coatings with Internal Hierarchy

The results presented in this thesis are focused on the surface modification by polyelectrolytes and polyelectrolyte copolymers. The internal structural hierarchy originate thereby from the self-assembly processes at different length scales. To generate different levels of hierarchy, the coatings were constructed by using either the layer-by-layer (LbL) deposition method (lateral chemical structure), the adsorption of supramolecular aggregates (lateral topographycal structure), or the combination of both. Using these techniques, one can control the properties of the coatings by varying the chemical structure of the polyelectrolytes, for instance, their charge density, thus providing a convenient way for their functionalization and the ability to tune properties of the surface. Therefore, we were working with systems which have variable charge densities. With this approach, we were able to produce thin and ultrathin nanostructured films with tunable properties and functionality.
