1. Polyelectrolytes on Surfaces and their Complexes with Surfactants, Thermodynamics versus kinetics
Abstract : The interfacial properties of polyelectrolytes, mainly cationic with various content of amphiphilic groups, and their complexes with an oppositely charged surfactant, sodium dodecyl sulfate (SDS), have been investigated using time-resolved ellipsometry. This thesis focuses on the kinetics and reversibility aspects of polymer adsorption and the control of the adsorption by regulating the electrostatic interactions. READ MORE

2. Adsorption of biopolymers and their layer-by-layer assemblies on hydrophilic surfaces
Abstract : It is widely known that surfaces play an important role in numerous biological processes and technological applications. Thus, being able to modify surface properties provides an opportunity to control many phenomena occurring at interfaces. READ MORE

3. Nanostructured surfaces created by the interactions of dendrimers and oppositely charged amphiphiles
Abstract : The research described in this thesis aims to understand the interactions between cationic poly(amidoamine) (PAMAM) dendrimers and small oppositely charged amphiphiles at the solid-liquid and air-liquid interfaces in relation to the bulk solution behavior. There is high interest in PAMAM dendrimers because they are well-defined polymers with a hierarchical architecture which makes them promising materials as nanocapsules and gene vectors. READ MORE

4. Structure-Property Relationships of Surfactants at Interfaces and Polyelectrolyte-Surfactant Aggregates
Abstract : The first part of this thesis is concerned with thestructure-property relationships in nonionic surfactantsystems. The main aim was to investigate how the surfactantstructure influences the adsorption at interfaces andinteractions between surfactant coated interfaces. READ MORE
