Transparenta, cellulosabaserade förpackningsmaterial med goda barriäregenskaper

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 […]

Nanocellulose based filaments for advanced applications. In situ SAXS studies of wood delignification.

To develop and characterize filaments for advanced applications, i.e. green smart textiles or conductive fibers. Use a flow-focusing setup and cellulose nanofibers as a main material for preparation of filaments with high mechanical performance. To understand  the fundamentals behind alignment and particle organization. To study impact of hydrolysis and delignification of wood chips on their structure

KAW Biocomposites

Technical objective The project is focused on materials design of biocomposites which are semi-structural, recyclable and/or biodegradable. The term “semi-structural” needs to be defined. If 30wt% glass fiber/polypropylene is selected as the reference material for substitution, it would mean that the modulus should be > 6 GPa and the tensile strength > 85 MPa. In

Lignin nanoparticles

The project is aimed for development and functionalization of nanoparticles (NPs) based on technical lignins. Due to natural origin of lignin and good biocompatibility, lignin NPs (LigNPs) can find application as targeted drug delivery vehicles for future implementation in biomedicine. Within the scope of this project, we aim to develop novel multifunctional lignin nanoparticles from

The effect of compaction parameters on the properties of high-deformable paper

This project addresses the challenges of producing high-deformable paper for 3D forming applications using the in-plane compaction process. Enabling 3D forming of advanced paper structures paves the way for complete elimination of plastic based packaging or partial replacement of plastic in multi-material packages, which aligns with current international strategies for a sustainable development of the

Karakterisering och kvantifiering av deformations- och skademekanismer i kartong under komplexa belastningsfall

Projektets mål är karakterisering och kvantifiering av deformations- och skademekanismer i kartong under komplexa belastningsfall. Sådana är praktiskta viktiga vid konvertering av kartong i allmänhet, men speciellt betydelsefulla vid 3D-formning av geometriskt avancerade strukturer. För att nå målet ska experimentella 4D datortomografiundersökningar kombineras med matematisk modellering.

Pre-project ForMAX beamline

This project is focused on SAXS measurements to study structuring of fibrilar systems under flow, such as 3D printing, electro spinning and fibre spinning. The project is in the framework of the feasibility study on the ForMAX beamline at MAX IV. Controlled alignment of for example cellulose nanofibrils is of high interest, since their mechanical

Develop contact-active antibacterial approaches on bio-based materials using LbL technique and their antibacterial mechanisms

Layer-by-layer coating technique has been shown their considerable advantages including fast and mild process, flexibility and easy to scale up comes to the surface functionalizations. One of the most pronounced functionalities is the antimicrobial approach. We are aiming at developing non-complicated methods for antibacterial properties on different substrates mainly cellulose-based materials using alternative cationic polyelectrolytes,

Novel Lignin Based Thermoset Resins

The project focuses on synthetic pathways to modify lignin to introduce chemical groups suitable for cross-linking reactions and elaboration on the mechanical properties of the formed materials. The main focus is allylation, introducing an allyl ether functionallity selectively on phenols, and thiol-ene reactions for cross-linking of the thermoset resin. This is performed on technical lignin
