During the last decade there has been a large focus on using wood-based fibres in new materials and there has also been an overwhelming development of the use of nanocelluloses (NCs) in new types of composites where the properties of the Cellulose NanoFibrils (CNFs) or Cellulose NanoCrystals (CNCs) are utilized to create unique material properties.

The project has the following purpose and aims: (a) Novel wet-stable, low density networks of cellulose nanofibrils (CNF) with a tailored 3D structure; (b) Tailored structures through controlled freeze-linking of the CNF followed by a formation of interpenetrated polymeric networks inside the cellulose network for controlled liquid spreading and liquid holding capacity; (c) Tailored 3D
This project is dedicated to understanding the properties of polymeric networks and composites thereof. Cellulose nanofibres and other fillers are included in polymeric matrices to enhance specific properties such as adhesive, mechanical or biological. The final goal is to generate next generation tissue adhesives in which bio-based materials are used to a larger extend. The
Unbleached Kraft fibers have been used to prepare lignin-containing CNF with interesting characteristics. The fibers and fibrils will be used in thermoplastic biocomposites, and structure-property relationships will be investigated.

Holmen is a major Swedish producer of paper and board products. Most of these products are based on softwood fibres. During converting of the products, they are plastically deformed in folding, creasing or embossing operations. This deformation occurs both in a macro and microscale. It is therefore important to understand the influence of the raw

The fundamental facet of this project is to design and fabricate functional composite filaments based on CNF and polymers. The aim is to prepare filaments with superior mechanical properties and/or advanced functions. In this project, we are going to control the interaction between individual CNFs during flow assisted assembly using different heterofunctional polymers. The project is

The project work focuses on the development of functional nanostructured carbon material with large specific surface area and derived from sustainable materials, mainly lignin. Approaches such as electrospinning, freeze-casting as well as 3D printing can be involved. The possible applications of the carbon material can be electrodes in high-performance energy storage devices, for example, supercapacitors.
Den vanligaste metoden att framställa papper görs genom den så kallade Kraft-processen. I denna process tas olika komponenter bort från träet för att möjliggöra vidare framställning av högkvalitativ cellulosa och papper. En viktig del i Kraft-processen är den så kallade avlignifieringen. Under denna process öppnas cellulosaväggen och porer av storleken från 20 till 50 nanometer

I mark och hav ansamlas på grund av mänsklig aktivitet stora mängder plaster, ofta från påsaroch förpackningar. I värsta fall tar det flera hundra år för naturen att bryta ner dessa plaster.För att åtgärda denna miljöförstöring räcker det alltså inte bara att vi blir bättre på att återvinnaoch slänga vårt plastskräp på rätt sätt, utan
