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 […]
Recyclable and Creep Resistant Polyethylene – through Transient Cellulose Networks
Plastics enhance almost every aspect of human life from food consumption to medical care and even energy production. However, the often superficial use of plastics means that a large fraction of this versatile class of materials is not recycled but, instead, burned for energy recovery, buried as waste in landfills, or worst case simply discarded […]
Development of advanced methods for investigation and counteracting of membrane fouling during recovery of extracted wood components in biorefinery applications
This project aims to develop and use advanced characterisation methods to investigate how process parameters can be utilised to decrease the effect of surface fouling during separation for recovery of high molecule weight hemicelluloses in biorefinery applications. Characteristics of formed fouling layers that are difficult to measure: thickness as well as cohesive and adhesive strength, […]
Scale-up of sustainable production of dialdehyde cellulose and dialcohol cellulose
The project is a collaboration between Chalmers, KTH, BillerudKorsnäs and TetraPak. The aim of the project is to develop a closed or semi-closed techno-economical feasible process for production of Dialdehyde cellulose, DAC and its derivatives with a target to replace plastic materials in different applications such as thermoforming, extrusion and moulding. The project will have […]
Biocomposites from fibres and nanocellulose
The project is a post-doc project within WWSC 2.0 The engineering aim brought forward in the project is to produce composities by using chemically modified fibres and nanocellulose and use these as reinforcing-structural elements in a polymer matrix. The resulting composites material must be manufactured with conventional, possible slightly modified, polymer processing techniques in order […]
Injection moulded polymers – imaging of composites with x-ray techniques
Investigation of the structure induced by processing of traditional polymers for packaging application (such as LDPE or HDPE) as well as new cellulose and ligno-cellulose based materials. Characterization include SAXS/WAXS imaging, birefringence, STXM, and CT.
Adsorption av funktionella polymerer tillcellulosa i blekningssteget – ett sätt att utöka fibrernas egenskaper
The purpose of this proposed project is to suggest new pathways for the adsorption reactions to cellulose fibers in the bleaching step in the kraft pulp process. The long-term aim is to develop a flexible knowledge platform that can be used for designing functionalized surfaces of the cellulose fibers in the bleaching step, using by […]
Production of new high-performance CNF biocomposites (Cellulose nano-composites)
The aim is to develop new methods for large-scale melt processing of thermoplastic composites reinforced with high content of cellulose nano-fibrils. The goal is a thermoplastic process capable of mixing and shaping thermoplastic compositions reinforced with 30 % or more nano-cellulose, obtaining a functional composite stiffness at least 10 times of the polymer matrix. Alternatively, […]
Processing & Mechanics – Bio-based Polymer Composite Materials
With this project, we aim to advance the understanding, synthesis, manufacturing and modelling of biocomposites. In particular, we target polymers reinforced with cellulose fibers that have been grafted with cellulose nano crystals, the wood-based cellulose fibers and nano crystals are an important resource from the Swedish forest industry. The idea is to scale up a […]
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 […]
All wood composites
Lightweight structural composites are a great way to reduce overall weight. Bio-based composites are used to replace fossil-based materials in non-structural applications. This project will develop new lightweight structural materials that are comprised of bio-based constituents. One of the most important aspects to understand when developing new composites is the interface functionalization chemistry and its impact on rheological […]
Polysaccharide films – formation and properties
Turning wood-based polymers and particles into films is vital for majority of their utilization (packaging, support materials) and for fundamental analytics (model surfaces for adsorption, interaction studies, strength characterization). Cellulose, hemicelluloses and lignins have distinct (from one another) intrinsic film formation behavior and properties that span from solubility, molecular weight and flexibility, and polarity. Main […]
