DTNW is an ideal partner for your ideas. We conduct goal-oriented research on your behalf. Our scientists accompany you from the first conception to the implementation in a new technology.
With four research groups, DTNW has an extensive range of topics and a lot of experience. If you have any questions about contract research, please contact the managing director Prof. Dr. Jochen Gutmann or the heads of the respective working groups.
Working Group Environmental Technology and Catalysis
- Development of catalytically active textiles: immobilization of enzymes and organocatalysts for improved syntheses and processes in the fields of fine chemistry, pharmaceuticals, food and textile technology.
- Development of innovative adsorber textiles for valuable metal recovery and environmental protection: raw material efficiency, recovery of secondary raw materials (“textile mining”), groundwater and soil remediation.
- Replacement of conventional chemical processes by alternative processes and materials: use of enzymes, supercritical media and ionic liquids, biopolymers, polylactide fibers, etc..
- Development of electrically conductive textiles: textile-based heating elements, textile-based solar cells, photovoltaics.

Working group Interfacial Phenomena and Physical Technology Group
Physical methods for the functionalization of polymer surfaces are used to develop the basis for new filter materials, composite systems, products for textile construction and the automotive industry.
- Polymer physics: polymers from renewable raw materials (polylactide), fiber physics, aging and degradation of textile fiber materials
- Volatile surfactants: development of methods for the analysis and application of volatile amphiphiles (fragrances) in interfacial processes (e.g. coating, printing, emulsification, spraying, cleaning)
- Wetting and transport processes in heterogeneous media: air and liquid filtration, oil-water separation, heterogeneous surfaces
- Surface modification: fluorine-free / low-fluorine hydrophobic coatings, underwater oleophilicity, photo-induced deposition of functional coatings
- Sustainable dyeing, digital printing on textiles
