1. Cellulose derived carbon dots : From synthesis to evaluation as multifunctional building blocks in biomedical scaffolds
Sammanfattning : The implementation of biobased and biodegradable polymeric materials in biomedical applications is often coupled with issues related to their insufficient mechanical properties or limited bioactivity. In this thesis, a perspective on valorization of biomass is presented, demonstrating the transformation of cellulose into biobased carbon nanomaterials with the potential to serve as multifunctional property enhancers in polycaprolactone (PCL) scaffold materials for tissue engineering.

2. Ring-opening polymerization from cellulose for biocomposite applications
Sammanfattning : There is an emerging interest in the development of sustainable materials with high performance. Cellulose is promising in this regard as it is a renewablere source with high specific properties, which can be utilized as strong reinforcements in novel biocomposites. LÄS MER
3. Innate Confinement Effects in PCL Oligomers as a Route to Confined Space Crystallisation
Sammanfattning : In this work, an in-depth analysis of crystalline characteristics has been performed for a unique set of strictly monodisperse poly-ε-caprolactone (PCL) oligomers. The molecules have different sets of end groups with various degrees of bulkiness and hydrogen bonding potential, affecting their aptitude to pack in ordered crystal structures. LÄS MER
4. Lignocellulose Biocomposites– A Comparison of Wood Fibers and Microfibrillated Lignocellulose
Sammanfattning : All-lignocellulose composites, meaning densified fiber or fibril materials without added binder, show interesting mechanical properties and can be eco-friendly. Composites based on hot-pressed microfibrillated lignocellulose (MFLC) and lignocellulosic wood fiber (WF) reinforcements are compared with respect to processing, structure, mechanical properties, and eco-indicators.

5. Surface Modification of Nanocellulose towards Composite Applications
Sammanfattning : Nanocelluloses have attracted great interest during recent decades owing to their renewability, abundancy and remarkable physical and mechanical properties. The aim of this work was to investigate new strategies for surface modification and functionalization of nanocelluloses and their subsequent incorporation in polymer-host matrices. LÄS MER
