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.

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
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,
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

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

Rheometry explores the relationship between forces and motion through (continuum) constitutive relations and suitably defined material functionsi. Rheometry is important for soft matter from two main reasonsii: (i) to investigate correlations between molecular structure and material behavior and (ii) to attempt the prediction of flow behavior in complex situations using material parameters determined in simple,

The possibility of producing three-dimensional advanced paper structures create the conditions for replacing plastic-based solutions or plastic details in packaging with multi-material and contributes in an essential way to strategies for a sustainable social development . Within this context, the project deals with the challenge of producing highly stretchable paper for 3D forming applications through in-plane

The objective of this research project is to develop a deeper understanding on how chemicals can influence the dry strength of biocomposites, in our case board and tissue. The following parameters will be considered: -Influence of chemistry (mainly polyelectrolytes, PE) on bond and network strength -Influence of PE configuration and loading (charge) on bond and
