6. Exploring Biopolymer-Clay Nanocomposite Materials by Molecular Modelling
Sammanfattning : In this thesis, bio-nanocomposites made from two alternative biopolymers and montmorillonite (Mnt) clay have been investigated by molecular modelling. These biopolymers are xyloglucan (XG) and chitosan (CHS), both of which are abundant, renewable, and cost-effective. LÄS MER
7. Corrosion protection and nanomechanical properties of waterborne acrylate-based coating with and without nanocellulose on carbon steel
Sammanfattning : Corrosion protection is commonly achieved by applying a thin polymer coating on metal surfaces. In this doctoral thesis, a waterborne hydroxyacrylate-melamine copolymer coating was used for this purpose. The first step was to find the optimal curing conditions. LÄS MER
8. 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.

9. Processing and properties of nanocomposites based on polylactic acid, chitin and cellulose
Sammanfattning : The production of bio-based and biodegradable nanocomposites has gained attention during recent years for environmental reasons; however, the large-scale production of these nanocomposites still poses challenges. The objective of this work has been to prepare bio-based and biodegradable nanocomposites via liquid-assisted extrusion and to gain a deeper understanding of the process and the relationship between the process, composition, structure and properties.

10. Compression-moulded and multifunctional cellulose network materials
Sammanfattning : Cellulose-based materials are widely used in a number of important applications (e.g. paper, wood, textiles). Additional developments are suggested by the growing interest for natural fibre-based composite and nanocomposite materials. LÄS MER
