Membranes

Technical membranes can be used wherever mixtures of substances need to be separated. The core competencies at the IGB lie in the shaping and functional coating of membranes. In the innovation field, we develop both hollow fiber and flat membranes via phase inversion processes and can manufacture them from laboratory to pilot scale. In addition, we have established a wide range of roll-to-roll coating processes (wet chemical, plasma processes) to optimize the separation or fouling properties of membranes.

For the development of new membranes, we also have extensive know-how in material synthesis (polymers, ceramics) and the characterization of materials, surfaces and membranes. With our own test rigs, we carry out application studies for our partners in the fields of topic listed below.

 

Moisture management

Humidifier membranes for water management in mobile fuel cell systems

 

Gas separation

O2 separation at high temperatures with ceramic hollow fiber membranes

 

Micropollutants

Membrane adsorbers for the separation of micropollutants from drinking water

 

Hydrogen technologies

Ionomer mixed-matrix membranes for electrolysis and fuel cells

 

Water purification

Forward osmosis membranes for gentle processing of complex mixtures

 

Green membranes

New filtration membranes via phase inversion processes with green solvents

Development of membranes from different materials

Polymer materials offer convincing advantages such as low costs, good processability and a wide range of possible applications. We work with commercially available polymers as well as with their modifications and, for example, (block-co)polymers produced in-house by means of radical polymerization.

Polymer membranes can be further optimized: Tailor-made mixed-matrix membranes can be created by adding particle inserts.

If the application requires more extreme conditions, for example regarding temperature, we work with fully ceramic membranes.

Production of different geometries

Fraunhofer IGB uses different processes for the production of various types of membranes up to pilot scale.

Hollow fibers, which are characterized by a high specific surface area, are produced by wet spinning with different diameters and from different materials; asymmetric structures are also possible.

In the case of flat membranes, we manufacture both dense and porous structures; one focus is on mixed-matrix systems.

Coating of membranes

To further improve the separation properties of membranes, they can be modified by various coating techniques, such as wet chemical coating, plasma treatment, interfacial polymerization, sol-gel process or electroless deposition. We have the equipment for continuous roll-to-roll coating for both hollow fiber and flat membranes.
