Polymeric membrane materials
Membranes derived from synthetic polymers are widely used in for separation processes in medical and technical application. Main fields of application are hemodialysis, drinking water and waste water treatment, beverage and food industry (clarification) or pharmaceutical industry (sterile filtration). Micro-, ultra- and nanofiltration as well as reverse osmosis are well established membrane based separation techniques.
Despite world-wide intensive research activities fouling is still the major challenge in membrane technology.
Due to the growing demand for sustainable energy supply and the advantages over conventional energy generation systems (e.g. combustion engines), the fuel cell technology and Li-ion batteries have received much attention in the last decades. The main disadvantage of today's fuel cell systems is their lack of CO tolerance, inadequate conductivities at low and moderate temperatures (100-130 ° C; MTPEM) over a wide humidity range and the undesired fuel passage (especially in DMFC). The expansion of renewable energy generation systems (wind power and photovoltaic), forced research activities in the field of energy storage systems like redox flow batteries.
The research in the group polymeric membrane materials at the IPF is focused on three main topics:
- Membranes (MF, UF, NF/RO) with reduced fouling tendency and chlorine resistance (NF/RO)
- Development of new ion conductive membrane materials (cation exchange and anion exchange materials) for electrochemical applications (eg. fuel cells and energy storage systems)
- Preparation of membranes using solvent-free processes
