1. Cellulose-based Nanocomposites – The Relationship between Structure and Properties
Sammanfattning : Nanocellulose materials extracted from various types of biomass have recently attracted significant attention. Due to their remarkable mechanical properties, large surface area and biodegradability, they can be promising reinforcements in nanocomposites. LÄS MER
2. 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.

3. Improving properties of poly(lactic acid) biopolymer for use in food packaging
Sammanfattning : The petroleum-based plastics are widely used for food packaging applications because of their low cost, easy processability, and tunable properties to meet the specific needs of food packaging. However, these polymers are non-biodegradable, leading to a substantial amount of plastic waste in both land and marine ecosystems. LÄS MER
4. The effect of wood properties on oxidative isolation of cellulose nanofibrils and characterization of networks
Sammanfattning : Wood is a natural resource that has been an integral part of society for as long as humans have been on Earth. From serving as fuel for fire and construction material the applications of wood has been developed in modern times and only surged as a consequence of societal strive for sustainability and usage of green resources.

5. From bio-based residues to nanofibers using mechanical fibrillation for functional biomaterials
Sammanfattning : Bio-based resource utilization in different forms has been driven by societal, industrial and academic research interests towards the development of “green”, sustainable materials from renewable sources. Within this context, exploiting biomass from different industrial residues is further advantageous from an environmental and economic point of view, leading to minimization of residues by means of waste treatment and to the development of high-addedvalue- products.
