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 […]
Expandable cellulose-based capsules
The development of expandable capsules holds a great promise for various advanced engineering applications. Preparation of such materials using renewable and sustainable resources is particularly attractive, where the development is driven by an increased global interest in new generations of green products that can meet the demands of the modern society. 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 […]
Study of the multiscale networks of hemicellulose hydrogels by scattering techniques
The aim of the project is to develop multifunctional soft materials (hydrogels) from hemicelluloses for biomedical and food applications. We combine chemo-enzymatic methods to modify the molecular structure of the hemicelluloses and to tailor their assembly and rheological properties. In this project we want to understand the assembly mechanisms that drive the gel formation upon […]
Design for Circularity: Lignocellulosic based Thermoplastics – FibRe
Global warming is one of the largest threats ever to our planet which can completely alter our living conditions. Human contributions to emissions of green-house gases must decrease, and a drastically decreased use of fossil resources is a key step to achieve this. Daunting 320 million tons of plastics are annually produced in the world, […]
Processability of modified fibres for complex shaped parts
There is a drive towards the use of single-component materials in different applications, for example in opening and closure of packaging products and in single use plastics (SUP). This opens up the possible use of cellulose-based products, but increases the demand for new modification strategies for fibres. Modifications aiming at improving their processability and final […]
Multifunctional fibres for different end-use applications
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.
