All wood cellulose films from flow
The project is on composites that comprise dominantly wood-based components. Fundamental endeavors are on orientation of cellulose nanomaterials and fibers in films. This is mediated via flow and shear. Cellulose body interactions are tuned by tuning particle surface characteristics. Rheology, crystallinity, strength and barrier performance are used to assess the products and the process. (part […]
Multiscale modelling and testing of biocomposites for equestrian sports
The aim of the project is to advance both the understanding and modelling of the mechanical response of biocomposites. In particular, we target biopolymers reinforced with cellulose fibres, the latter which is an important resource from the Swedish forest industry. The idea is to link advanced in-situ experimental testing (microscopy under mechanical loading) and numerical […]
Oxidized hemicelluloses for films and gels
The project investigates properties and utilization of oxidized hemicelluloses.
Turning the cold NaOH(aq) into a powerful processing system for cellulose by utilizing its abundance of CO2 – a step towards sustainable textile processes
Today, there is an urge to meet the increased textile consumption by wood- and recycled cellulose textiles, based on new sustainable dissolution concepts for cellulose. Still, there are only few solvents capable of dissolving the intricate cellulose structure while being environmentally friendly and industrially viable. One of them, experiencing a renewed interest is undoubtedly cold […]
Melt and film properties of modified Arabinoxylans
In this project, “Melt and film properties of modified arabinoxylans” will be explored. We have in a previous project developed a route (via chemical modification) to obtain meltable arabinoxylans. In this Project we will examine the rheological properties of the melt and correlate these to the physico-chemical structure of the modified AX. In parallell we […]
Investigation of membrane fouling during microfiltration of wood components
Development of efficient separation processes are crucial for the realisation of the biorefinery concept, which is important to enable the substitution of fossil raw materials for production of materials and chemicals. Membrane filtration as a pressure driven operation has the potential of being a very energy efficient separation method in this application. However one of […]
