Sustainable textiles
Our research team continues the development of the Ioncell® process. The focus is on textile recycling and sustainable dyeing processes.
Biopolymer Chemistry and Engineering
The Biopolymer Chemistry and Engineering group is led by Prof. Michael Hummel. The group explores the structural features and thermochemical behavior of biopolymer solutions and suspensions to produce value-added products. Fundamental studies are directed towards the modification of biopolymers following the principles of green chemistry and enhancing the understanding of the visco-elastic properties of biopolymer solutions and suspension.
The application focus of the group is on sustainable textiles and biobased carbon materials.
The application focus of the group is on sustainable textiles and biobased carbon materials.
Research areas:
Biobased carbon materials
We investigate the use of wood-derived polymers and other biopolymers as bio-based alternative precursor material for various applications.
Carbohydrate chemistry
Our research is aiming at introducing additional functionality to biopolymers with a special focus on textile applications and to develop suitable analytical tools
Cellulose films
Our research focuses on the use of the Ioncell® technology to produce high-strength films through continuous extrusion.
Rheological behavior of biopolymer solutions and suspensions
Traditional and novel solvent systems are explored to dissolve various biopolymers and non-polymeric constituents. The solutions or suspensions are characterized by a comprehensive set of rheological tools (shear, capillary and extensional rheometers).
Analytical tools
Analytical chemistry is needed throughout the modification and/or manufacturing process of biomaterials. Knowledge on the chemical composition and molar mass of biopolymers is essential and thus we aim to develop new strategies for detailed biopolymer characterization.
Michael HummelA thoughtful use of biopolymers can help us to create a more sustainable society.
