The main research topic of the nanocomposites group is the production of polymer compounds using nanoscale additives to adjust the electrical, mechanical or thermal properties of thermoplastic polymers. Beside a research focus on the properties of the compounds, work is also carried out on processing techniques for the manufacture of the compounds, and on the development of analytical methods to measure the nanostructure of the materials.

The introduction of nano-scale additives into polymer matrices is an extremely effective method of adjusting the properties of the composite. The electrical, mechanical and thermal properties can be adjusted and additional functionalities (such as sensorics) can be integrated.

Processing techniques for the production of nanocomposites

The research aim is the development of new compounding techniques and the adjustment of conventional methods in order to optimize the dispersion of the nanoparticles in the polymer matrix. Supercritical fluids, high-performance ultrasound and low-viscosity nano-suspensions are used.


Analysis techniques for the investigation of nanocomposites

Offline measurement methods developed at the Fraunhofer ICT enable the rapid and cost-effective analysis of nanocomposites. Emphasis is also placed on inline measurement technologies for process-integrated quality control.



Photocatalysts can be used to generate antibacterial properties on surfaces on exposure to light, without the use of chemical agents. The effect is based on the oxidation potential of the photocatalysts when irradiated with light of short wavelengths. The oxidation of the organic matter of bacteria leads to their inactivation.
