1. Surface force studies of association phenomena at solid-liquid interfaces
Abstract : The main topics of this thesis, association phenomena inbulk and at solid-liquid interfaces in polar and non-polarmedia, were studied by a range of methods. Direct forcemeasurements employing the interferometric surface forceapparatus (SFA) was the chief technique. READ MORE

2. 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

3. 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

4. Dynamic interactions of interfacial polymers
Abstract : The relationship between the amount and conformation of apolymer at the solid-liquid interface, and the resultinginteraction forces between two such surfaces has beeninvestigated. With a degree of control of the polymerconformation, by varying the temperature, solvent quality,polymer charge density etc, it has been possible to measure andinterpret the resulting changes in the surface interactions.
