Membranes and Functional Films


The research activities in the Membranes and Functional Films department are oriented towards resource-efficient processes for producing membranes and films. In the case of membranes, this ranges from hollow fibers to flat membranes for gas separation, nanofiltration of organic solvents and fuel cells. The work on films focuses on refining the surfaces of existing systems, for example, by applying functional coatings. The majority of the films are used by end consumers and are subject to a constantly changing, socially defined requirement profile. This includes low contaminant permeation, enhanced biodegradability and the ability to completely empty residual  contents. The development of proteinogenic materials is another key focus of the research carried out in the department.
