1. On the interactions in cellulose systems : surface forces and adsorption
Abstract : In this thesis the interactions in cellulose systems havebeen studied with emphasis on surface forces and adsorptionphenomenon. The study was limited to surfaces and polymers ofinterest for papermaking. READ MORE

2. Design of Cellulose-based Materials by Supramolecular Assemblies
Abstract : Due to climate change and plastic pollution, there is an increasing demand for bio-based materials with similar properties to those of common plastics yet biodegradable. In this respect, cellulose is a strong candidate that is already being refined on a large industrial scale, but the properties differ significantly from those of common plastics in terms of shapeability and water-resilience.

3. Specific ion effects in carboxymethyl cellulose adsorption on cellulose: A step towards modification of fibers in fiber line
Abstract : The increasing global demands for paper products have fuelled the research in developing new fibers from existing industrial processes. The adsorption of carboxymethyl cellulose (CMC) has been shown to improve the tensile properties of the paper significantly. READ MORE

4. Polyelectrolyte adsorption on oppositely charged surfaces - Conformation and adsorption kinetics
Abstract : Denna avhandling presenterar experimentella studier av polyelektrolytadsorption på motsatt laddade ytor, där substrat av både kiseloxid och blekt barrsulfatmassa har använts. Ett huvudsakligt syfte med denna forskning var att karaktärisera konformationen hos adsorberade skikt av katjonisk polyakrylamid (CPAM) i jämförelse med katjonisk dextran (Cdextran) och relatera denna information till inbindningskapaciteten av kolloidal kiselsyra.

5. Nanolatexes: a versatile toolbox for cellulose modification
Abstract : Cellulosic materials are widely used in our everyday lives, ranging from paperand packaging to biomedical applications. However, in most applications, cellulose must coexist with hydrophobic polymers which can be challenging due to its hydrophilic character. This has encouraged the exploration of chemical and physical modifications of cellulose. READ MORE
