Fibers, and the polymers they’re made of, are the building blocks of all textile materials. Therefor at CTSE we focus on developing new polymers, modifying existing polymers and create new types of fibers and fiber structures. Approaching this research from a ‘molecule to filament’ viewpoint offers many possibilities to tune the final materials to the demands of the applications in terms of energy-use, mechanical performance, unique properties and so on. One key research area is that of electrospinning of nanofibers and nanofibrous membranes. They can be thought of as a novel class of materials consisting of very thin fibres with typical diameters below 500 nm. As a comparison, classical “textile” fibres have diameters between 50 and 200 µm. The small diameter gives nanofibrous membranes interesting characteristics such as a large surface area, a high porosity (> 90%) and improved mechanical properties compared to the bulk polymer. These materials possess a lot of potential for a broad field of applications such as in wound dressings, advanced composites, filter technology, batteries, sensors and much more. A glossary of some of our current research topics is given below.
Model-based design for polymeric material applications
Applying multi-dimensional simulation tools to support polymer technology.
Small fibers, big warnings: how tiny threads visualize threats.
Built from a combination of polymers and stimuli-sensitive dyes, colorimetric nanofibrous sensors warn us against conditions that threaten our health or safety via a color change.
As over 60% of all orally taken drugs suffer from being poorly water soluble, our research shows that incorporating the drug inside nanofibers can increase the solubility tremendously.
Thermoresponsive polymers for environmentally friendly electrospinning
How we can make the future of electrospinning greener
Thanks to their solubility in non-toxic solvents, thermoresponsive polymers help in making electrospinning a more eco-friendly production process for crosslinked or non-crosslinked nanofibers with varying affinity for aqueous media.
