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 […]

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

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

Surface characterization of polymeric composites and their interaction with biological tissue

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

Cavitation Fibrillation of Cellulose Fibres (CaFiCeFi)

The project is of explorative nature and aims on mapping the destructive nature of cavitation on cellulose fibres. Neither cavitation nor the dispersion of cellulose fibres in its constituents (cellulose fibrils for dissolving pulp fibres) is fully understood. The project objective is to guide whether cavitation is a mean for efficient and dedicated fibrillation at

Flow assisted assembly of biocomposite filaments based on Cellulose Nanofibrills (CNF)

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

Enzyme discovery and enzyme application on wood

Our project aims to identify enzymes that have the ability to increase the efficiency of the biorefinery process, designed for the production of biofuels, -chemicals, and -materials. Specifically, this project aims to find, characterize, and utilize, enzyme that attack specific bonds in the complex biomass structure, to increase the saccharification efficiency of cellulolytic enzyme cocktails

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

Conducting cellulose fibres and yarns for circular electronic textiles

Conducting fibres and yarns are essential components of the next generation of wearable electronics that seamlessly integrate electronic function into one of the most versatile and most widely used form of materials: textiles. Necessary requirements are a high degree of wash and wear resistance. Traditionally, colouring of cotton, viscose and lyocell fibres is done with
