1. Properties of poly(lactic acid) in presence of cellulose and chitin nanocrystals
Sammanfattning : Plastic based materials are widely used for industrial and domestic packaging application. However, disposal of such petroleum-based materials e.g. polyethylene (PE), polypropylene (PP), and polyethyleneterephthalate (PET) has become a huge threat to the environment. LÄS MER
2. Multifunctional Glyconanomaterials : Applications in Biorecognition and Drug Delivery
Sammanfattning : This thesis consists of three parts, which revolve around the fabrication of multifunctional glyconanomaterials (cellulose nanocrystals, chitin nanocrystals, mesoporous silica nanoparticles) and the development of their applications in biorecognition and nanomedicine.Part one presents a detailed introduction to glyconanomaterials, focusing on cellulose nanocrystals, chitin nanocrystals and mesoporous silica nanoparticles, including their general preparations, properties and applications.

3. 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.

4. Tailoring Cellulose Nanofibrils for Advanced Materials
Sammanfattning : Cellulose nanofibrils (CNFs) are nanoscale fibers of high aspect ratio that can be isolated from a wide variety of cellulosic sources, including wood and bacterial cellulose. With high strength despite of their low density, CNFs are a promising renewable building block for the preparation of nanostructured materials and composites. LÄS MER
5. 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
