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

Lignosulfonate composited with electronic polymers for large scale energy storage applications

A renewable resource from existing forest industry is the black liquor that mainly goes to combustion. The dominating biopolymer in black liquor is a derivative of lignin. At LiU we have shown how lignin and lignosulfonate (LS) can be used to store charge into biopolymer electrodes, and built supercapacitors/supercabatteries of such electrodes. In these electrodes,

Karakterisering och kvantifiering av deformations- och skademekanismer i kartong under komplexa belastningsfall

Projektets mål är karakterisering och kvantifiering av deformations- och skademekanismer i kartong under komplexa belastningsfall. Sådana är praktiskta viktiga vid konvertering av kartong i allmänhet, men speciellt betydelsefulla vid 3D-formning av geometriskt avancerade strukturer. För att nå målet ska experimentella 4D datortomografiundersökningar kombineras med matematisk modellering.

Porous, optical and IR-absorbing cellulose for solar evaporators

This project aims at investigating how conducting polymers interact with forest-based materials to form hierarchically nanostructured aerogels. We will develop protocols for fine tuning the structural and mechanical properties of cellulose-base conducting aerogels, and to control the penetration of solar absorbers (i.e. conducting polymers) in the nanostructured forest-based aerogels. We will study how energy is

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

Soft cellulose-based robotics

The project is focused on the development of novel concepts for soft electromechanical actuators and robotics based on nanocellulose composites. Nanocellulose foams are light weight and compressible, making them ideal for functionalization for actuators. Magnetic and electronic functional composites will be developed and fabricated into novel device concepts. The project is part of WWSC.

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

Develop contact-active antibacterial approaches on bio-based materials using LbL technique and their antibacterial mechanisms

Layer-by-layer coating technique has been shown their considerable advantages including fast and mild process, flexibility and easy to scale up comes to the surface functionalizations. One of the most pronounced functionalities is the antimicrobial approach. We are aiming at developing non-complicated methods for antibacterial properties on different substrates mainly cellulose-based materials using alternative cationic polyelectrolytes,

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

Novel Lignin Based Thermoset Resins

The project focuses on synthetic pathways to modify lignin to introduce chemical groups suitable for cross-linking reactions and elaboration on the mechanical properties of the formed materials. The main focus is allylation, introducing an allyl ether functionallity selectively on phenols, and thiol-ene reactions for cross-linking of the thermoset resin. This is performed on technical lignin
