1. Polysaccharide thin film studies - Adsorption of oxidized xylan on cellulose
Sammanfattning : Wood xylans are renewable natural materials that have potential for future use in bio-based products. However, their high price and low production capacity restrict their industrial use and current applications. This research aimed to explore the potential of wood xylans for film applications.

2. Theoretical and Experimental Studies of Polymer Adsorption and Polymer Mediated Interactions
Sammanfattning : Polyelectrolyte adsorption and polymer mediated interactions in different colloidal polymer systems have been studied in this work. Theoretical methods and experimental techniques are combined, in order to obtain more general reliable results, as well as a deep understanding of the molecular mechanisms that are responsible for the observed behaviors.

3. Towards compatibilization of cellulose nanofibrils in polymer matrices : Polymer design for mediating the nanofibril–matrix interface
Sammanfattning : Magnifying the nanostructure of wood reveals the features of an extraordinary nanocomposite material. In this nanocomposite, long fibrils of semicrystalline cellulose, with a cross-section in the nanometer range and length up to several micrometers, are embedded in an amorphous matrix made of other polymeric components.

4. Chemical Modification of Electrospun Cellulose Nanofibers
Sammanfattning : The forest industry is a large part of the Swedish economy and the export of pulp, paper and wood products constitutes 11% of the total Swedish export of goods. The main product of a pulp mill is purified cellulose, which has many great properties like biodegradability and non-toxicity. LÄS MER
5. Surface Modification of Cellulose by Covalent Grafting and Physical Adsorption
Sammanfattning : The interest in new environmentally friendly cellulose‐based productshas increased tremendously over the last years. At the same time theSwedish forest industry faces new challenges in its strive to increase the utilization of cellulose fibers in high‐value end‐products. LÄS MER
