6. Structures of Polyelectrolyte Multilayers and Preasorbed Mucin : The Influence of Counterions
Sammanfattning : The focus in this thesis has been to gain a fundamental understanding of how different type of salts affect preadsorbed polyelectrolytes, both natural and synthetic. The knowledge from the fundamental work is then applied on a commercial system to investigate if the efficiency can be enhanced. LÄS MER
7. Interaction between thin interfacial layers : the influence of polyelectrolyte multilayers on paper strength

8. On the Adhesion Between Substrates Covered with Polyelectrolyte Multilayers
Sammanfattning : This thesis examines the formation of Polyelectrolyte Multilayers (PEM) on cellulose fibres as a new way of influencing the fibre surface and the adhesion between wood fibres. The aim of the study was to enhance the fundamental understanding of the adsorption mechanisms behind the formation of Polyelectrolyte Multilayers on cellulose fibres; to study how the properties of the layers can be influenced and to show how the properties of the layers influence the adhesion between the fibres and the strength of paper sheets made from the PEM treated fibres.

9. Development of New Bacteria-Reducing Surfaces
Sammanfattning : In recent years, antibacterial surfaces have been a subject of increased interest. Especiallyinteresting are non-leaching, contact-active surfaces that physically disrupts the bacterialcell using immobilised cationic polymers. Thus the risks of bacterial resistance and discharge of hazardous biocides is minimised. LÄS MER
10. The creation of antibacterial fibres through physical adsorption of polyelectrolytes
Sammanfattning : Contact-active antibacterial surfaces with irreversibly attached antibacterial com-pounds are a sustainable alternative to traditional biocides. No chemicals are released into nature and the antibacterial mechanism reduces the risk of the evolution of re-sistant bacteria. LÄS MER
