Large-scale extrusion of protein superabsorbents with cellulose fibres for hygiene applications
The project focus on producing sustainable superabsorbents (SAP) by utilizing fully integrated natural-based and biodegradable raw materials, combined with highly scalable polymer processing techniques. Extrusion of proteins combined with cellulose fibres, as a hygroscopic carrier for a water in-situ foaming process, is going to be implemented. The addition of blowing agents and reagents are going […]
Functional materials derived from wood and CNF
Functional composite materials derived from wood or CNF and studying their structure property relationship for energy harvesting, sensing and other applications.
Material properties of wooden material: scale effect
The use of wood as a building material because of its efficiency, sustainability, and durability is increasing. Wood is a renewable resource, it has low carbon impact and low embodied energy. The amount of energy needed for producing wood products is much less than comparable products made from other materials. In spite of its common […]
Controlling product characteristics on board machine utilization process data
Quality on any board and paper products is dependent on being able to maintain low variability within product characteristics. A common problem is that these characteristics are measured cannot be measured online in the production, and is the time resolution will therefor be very low. The product characteristics will be dependent on the process characteristics, where […]
Forest-based materials for optoelectronic devices
We explore the use and development of forest-based materials in organic and hybrid organic optoelectronic devices. We carry out fundamental materials studies combined with device design, fabrication and characterization.
Native cellulose’s interplay in materials and dispersions (CELLO)
This project supported by the Swedish Research Council (Vetenskapsrådet) focus on native cellulose´s interplay in materials and dispersions. The overall aim is to study and explain the intra- and intermolecular interactions of cellulose which occur during dissolution, in dispersions and in the regeneration of novel nanobiocomposite materials.
Novel use of native cellulose in dispersions and functional biocomposites
This project supported by the FORMAS and Interreg Sverige-Norge specifically focuses on design and preparation of cellulose-based nanocomposites with added functionalities such as e.g. barrier, antimicrobial, catalytic and electronic properties, starting from water-based solutions of wood cellulose.
Cellulose fibre/fibre interactions within molded fibre composites
This project aims to model cellulose fibre/fibre interactions using assembled CNF filaments produced by co-axial extrusion. These long, uniform filaments provide an excellent platform to investigate the impact of chemical and physical modification on joint strength. The findings of this work can then be used to a develop a better understanding of the interactions within […]

The aim of this […]
New specific chemical modifications for fibre functionalization including topo-selective modifications and advanced structure and chemical characterization
Identify robust modification strategies that unfolds a new generation of deliginified wet wood fibres with customizable properties. The scientific question that need to be addressed is strongly coupled to the apparent pore size of deliginified wet wood fibres and thereof the diffusion aspects of molecular/macromolecular/nanoparticle probes to homogenously bind to the exterior and interior of […]
Composite soft actuators derived from ionic polymers and cellulose nanofibrils
This project is to build up new soft actuators derived from polymers and cellulose nanofibrils via ionic interactions and supramolecular interactions. Both membrane actuators and fiber actuators are targetted. The applications of these suft actuators in sensing and soft robotics will be investigated.
Wood hemicelluloses: molecular structure and interactions in plant cell walls
Wood is a formidable composite material with unique biological functions (as secondary plant cell wall) and outstanding properties to be exploited in material applications. Hemicelluloses act as the molecular connection, interacting with cellulose microfibrils and lignins, contributing to wood integrity (biological function) but also to recalcitrance (technical challenge). The dynamics of hemicelluloses in hydrated form […]
