1. Polyelectrolyte complexes : their preparation, adsorption behaviour and effect on paper properties
Abstract : In this work, the formation of polyelectrolyte complexes (PECs) has been studied using a jet mixing method not previously used for mixing polyelectrolytes. The PECs were formed from two weak polyelectrolytes, i.e. READ MORE

2. Polyelectrolyte complexes : Preparation, characterization, and use for control of wet and dry adhesion between surfaces
Abstract : This thesis examines polyelectrolyte complex (PEC) preparation, adsorption behaviour, and potential use for control of wet and dry adhesion between surfaces. PEC formation was studied using a jet-mixing method not previously used for mixing polyelectrolytes. READ MORE

3. Controlling Structure and Water Miscibility of Polyion - Surfactant Ion Complex Salts
Abstract : The interaction between poylions and oppositely charged surfactant ions has been investigated. This has been done by using the pure complex salt (polyion + surfactant ion) as a point of departure. Different parameters of the complex salt have been varied in a systematic way and the effect on structure and water miscibility has been investigated. READ MORE

4. Phase Equilibria and Structures of Oppositely Charged Polymers and Surfactants in Water
Abstract : A new approach to the study of aqueous mixtures of oppositely charged polymers and surfactants has been introduced. Pure polyion-surfactant ion complex salts have been synthesized and used as the point of departure. The elimination of the simple ions reduces the number of components in the mixtures, thus greatly simplifying the system. READ MORE

5. Properties of Protein and Polymer Systems
Abstract : Interactions of proteins with other proteins, with polymers and with surfaces are of great practical importance within for instance protein purification, drug delivery, and food technology. The aim of this work is to increase the understanding of protein-protein, protein-polyelectrolyte, and protein-surface interactions, particularly concerning the role of electrostatic interactions in these systems.
